Customized web/desktop hybrid apps with EarthBrowser and AIR 1.5

Adobe AIR 1.5 is being released. It uses the SquirrelFish Javascript accelerator which is really cool. With the upcoming EarthBrowser Javascript API, having a fast Javascript engine will make it much easier to create not only customizable web applications with the EarthBrowser virtual globe embedded, but also a customizable desktop app using your same code base with the ability to work offline and have hooks into an embedded database.

What the? Creating your own AJAX style web app with the EarthBrowser API will be just a small step away from creating your own desktop application with your geo-content.

More on this later.

Live blogging Adobe MAX show

For some reason I'm off the Adobe feed aggregator, which is a bit of a bummer but I'll post about what's going on anyway.

Adobe Flash Catalyst? Don't know what it is yet but it's just been announced alongside Flash and Flex Builder.

Announcing an association with U2's Red initiative called Red Wire. Five bucks a month seems like a lot, at least for me, for an online news magazine. Goes to a very good cause though.

So far my favorite part was getting the high score on the free Asteroids machine in the lobby (19,710). Old School.

Showing off EarthBrowser Web Plugin at MAX

EarthBrowser was chosen as one of the finalists for Adobe Rich Internet Application of the year, I am very honored by the selection.

Please vote for EarthBrowser for the People's Choice Award (near the bottom):
http://adobemax08.com/na/experience/#?s=5&p=3

I've been working very hard to get the EarthBrowser Javascript API ready to show off at Adobe MAX next week. The API is nearly done and it is much more powerful than I first imagined it. With it you can put EarthBrowser directly on your website and control every aspect of the user interface, globe, camera, clock from a HTML script tag. It understands KML, JSON, XML, AMF and even Shapefiles with projected coordinates (I ported the proj.4 library to Actionscript). There is also the ability to smoothly animate features based on time coordinates for which I gave a Google "tech talk" about in July.

I've put up a small with the demo that I plan on showing off at MAX.
Please take a look here

All of that demo is written in Javascript in a couple of days. I'll be releasing the API documents and a free non-commercial license keys in the next few weeks when I've put the final polish on it.

Special thanks to Lucian Plesea for the help with the OnEarth WMS layer help and a big thanks to Peter Minton for his great work on the island shapefile dataset.

EarthBrowser at the Adobe MAX awards

EarthBrowser has been selected as a finalist in the Rich Internet Application category of the Adobe MAX awards.


If you are going to be at MAX, please stop by and say hello. I believe I'll be showing off the latest version of EarthBrowser from 6:30 - 8:30pm in the Moscone center on Monday Nov 17th.

I have to say that I'm pretty excited to be attending Adobe MAX this year. Flash/AIR is a very impressive platform for applications development, I'm pretty sure that I'll never go back to doing a GUI application in C++. The coding team for Flash Player and AIR have my highest respect for enabling such a powerful tool.

I hope to have the EarthBrowser website plugin API finalized and ready for the public by the time MAX starts. With it you will be able to create your own customized and self-branded virtual globe on your own website. Several companies have already contacted me about developing solutions for their geospatial offerings based on EarthBrowser. I also just finished a project for Autodesk to have EarthBrowser running on a kiosk with a 40 foot projection wall in their new San Francisco Customer Care Center. I hope to drop by and check it out when I'm down there, but the MAX show is keeping me pretty busy...

EarthBrowser and Amazon cloud computing

First a quick note: EarthBrowser has been named a semi-finalist for the Adobe MAX awards. It would be great to get to the finals but I'm just honored to have EarthBrowser be recognized by Adobe as a great use of their amazing Flash technology.

As you may already know, EarthBrowser is a virtual globe that runs on the desktop but that is only half of the story. The other half of the EarthBrowser service is running on a set of servers that manage the website, licenses and data services. Data ingest, processing and management is a pretty big task, but is perhaps one of the most fun tasks that I do and is also the best way to create great content for EarthBrowser. EarthBrowser can read most KML files but unfortunately there aren't many great dynamic KML datasets out there. Perhaps because KML was designed for static content.

My favorite dataset in EarthBrowser is the precipitation forecast model, especially when paired with the tropical storms dataset. It gives a really interesting idea of the extent of the storm and also what is going on inside of it.


Richard Stallman of GNU fame believes that cloud computing is a "trap" but he is using a very narrow definition of the term. Cloud computing seems to be thrown out there to describe anything from web based applications to software as a service, the differences are obscure but important. At least for me, what cloud computing means is that it takes what was once a very time consuming administrative task and turns it into a programming problem.

Managing the software stack, configuration and uptime of these servers is cumbersome task to say the least. Designing an algorithm that can launch and maintain a fault-tolerant clustered server setup with no user interaction is an extremely attractive business advantage and also a very cool programming problem. I have been doing some extensive investigation of Amazon Web Services and am now planning on deploying my entire server side infrastructure on the AWS platform. I have been using the Amazon S3 storage service for quite some time because it is simple and just makes so much sense. With the recent release of the Elastic Block Store and Elastic IP Addresses, Amazon has a complete and very powerful solution for self-configuring web services that can also easily save and restore state in the event of a system crash.

So now in addition to EarthBrowser, I am working on a side project, I'm calling it FireAnt, that will create a server setup that can scale from one small instance to a full blown cluster of servers. It will scale up by adding new servers and as the load increases and scale back down as it decreases saving you money in the process. The base server is running a modified version of GeoDjango with Apache and PostGIS. Pound is used for web server proxying when scaling up and each server can take over for any of the others in the event of a system failure. I may release the code as open source, but I am a little worried about the time it would take me to manage an open source project. There is Scalr which is an open source project that will do something similar but it has a minimum of 4 server instances and it is based on PHP. Yuck.

EarthBrowser web plugin satellite example

Good news! The US Space Command has just granted my request to redistribute satellite orbit data. Expect to see satellites coming to EarthBrowser soon.

Here's the first public example of the EarthBrowser plugin, it requires Flash 9. it shows the current position of the International Space Station. Use your mouse wheel if you have one, or click the globe and use arrow keys to zoom out and see the Hubble Space Telescope and the TOPEX/Poseidon satellites.



This is a simple example with no extra datasets or interface elements and limited zooming. I hope to have the Javascript API available sometime next month.

Imagine a zero-install, completely programmable virtual globe that understands KML on your website.

My iTunes Pirate Album

My alter-ego has been revealed...



I'm the drummer first mate on the pirate rock band HuckleScary Finn captained by my best friend Kevin Hendrickson. I'm afraid that I can't take credit for the huge resurgence in pirate themed activities here in the Portland area, but I'd like to think I got in on the ground floor.

Notable Portland Oregon Pirate links:
• Portland Pirate Festival
• Captain Bogg & Salty (best pirate band in the world).
• International talk like a pirate day
• Captain Henry's Pirate Store (a pirate merchandise only store)

What's in the EarthBrowser pipeline?

If you aren't interested in wading through my sleep inducing 30 minute Google presentation, I'm planning on detailing much of what I said in a series of blog posts.

Contrary to almost every bit of advice I've been given I'm going to lay most of my cards out on the table about the future of EarthBrowser. For a single guy trying to go up against multi-billion dollar corporations, I need as much attention as I can get. However I'm not going to reveal everything, I've got some pretty cool things under wraps for release later this year.

Flash 10: I'm very excited about Flash 10 and believe that it will open the door for real-time 3D in the web browser. For me the most important aspects of F10 are native matrix operations, hardware accelerated rendering and a shading language. This will enable EarthBrowser to have true 3D navigable terrain with mountains, valleys and even underwater exploration, right in your web browser or in the desktop authoring app. I am hoping to get a 50-100% increase in rendering speed and be able to do really pretty things like normal mapping and atmospheric scattering.

3D Collada models: I'm not really a big fan of the obsession by Google and MS to put accurate 3D buildings on the earth, but if you have the data it isn't really hard to do. I've got more interesting uses for 3D models which will become more apparent in future versions.

GPS track importing: A very easy feature to add for people to edit and share.

iPhone version: I still hold out hope for Apple and Adobe to get Flash running on the iPhone so I haven't allocated much of my bandwith to this project yet. However after some exploration of the problem space, I estimate it will be relatively simple to port from my current codebase due to the nicely abstracted rendering backend.

My next blog post will detail the geometry / time coordinate extension that I hope will make it into the KML standard at some point. Time coordinates are designed for use in feature animation, which is an obvious use but was never a design consideration for KML. I don't really have the time or desire to submit and shepherd a proposal through an OGC standards committee. Perhaps there could be something like the Boost Library for KML where proposed extensions are selected to become part of the standard after being tested and refined by use in the community. Seems like this would be a great place for me and the WorldWind developers to start taking a little initiative and advance the state of the art for virtual globes.

EarthBrowser presentation at Google

Last Tuesday I gave a 30 minute presentation at Google about the upcoming EarthBrowser Flash plugin. I also presented an enhancement to improve the expressiveness and utility of KML along with a demonstration with orbiting satellites. Many thanks to Michael Weiss-Malik and the great guys at Google for inviting me to talk about whatever I wanted to!




If you have problems with the embedded video you can see it on youtube.

In the presentation I go through some of the features and benefits of the EarthBrowser Flash plugin. Then I talk about giving time it's own coordinate in the geometry primitives in order to reduce KML file size and complexity as well as add new functionality. Toward the end I talk about future enhancements to the EarthBrowser desktop/web platform. I also mention that I'm developing an iPhone version.

Wow! C/C++, Python and Ruby running in Flash Player

Earlier this year I saw the demo of Quake running in Flash directly translated from C++. It was very impressive to say the least, Adobe has some great coders and the amazing advantage of having their code running on almost every computer with a web browser.

I just came across this post that talks about an open source backend to the LLVM that will enable C/C++, Python, Ruby, Perl, Lua and other languages to be targeted to ActionScript bytecode (the language the flash player runs). It sounds like it will need some more work and support of a new Flash player version but the possibilities are extremely exciting.

More detailed information on the initial LLVM work by Ryan Stewart here.

KML Extension, Julian Time

Creating a virtual globe that can view KML files as well as creating numerous datasets that have to use KML has given me what I feel is a unique perspective on the strengths and weaknesses of the language. It also gives me a really unique opportunity to enact some features in the language that I feel are needed. Hopefully at some point the OGC and Google will consider some of my suggestions once they are more formalized.

I've just come up with a *really* nice extension to KML that can drastically reduce the size of some datasets (e.g.: a 1.2 MB dataset is reduced to 60K) and at the same time enable functionality that is sorely missing. I'm not going to spill the beans on it quite yet since I've got another couple of enhancements that will enable even more great functionality. I'll present this extension and others when I give my talk at Google on the 15th of July. I'll post a video of that talk on this blog once its available.

Julian Time:
One of the less fortunate aspects of KML, in my opinion, is it's use of the ISO 8601 Date and Time Format. I understand why they did it; because it is human readable and a standard to hang their hat on. The processing overhead on parsing the date is significant, but not a deal breaker so why do I care?

Clearly the ISO time format should be left in, but there should be another option for specifying it as Julian Time. There are so many nice properties of julian time that I would be very surprised if Google Earth, Virtual Earth, ESRI and any other virtual globes don't all use it for their internal representation of time. It is a floating point number (usually a 64 bit double) that can be manipulated with standard mathematical functions. Anyone who has ever written a date library the naive way (as I have) has come to dislike all of the little details like days in a month, leap years and worst of all... time zones. Why not standardize on a time format that does away with all of that dreck and can be operated on like a regular number? You can add 3.5 days, subtract an hour and do simple comparison operations like greater than, less than and equal. I can't imagine ever using another internal representation.

Here's a conversion routine in Python:

# gdate is (year, month [1-12], day, hour, minute, second)
def julian_date(gdate):
if gdate[1] < 3:
M = gdate[1] + 12
Y = gdate[0] - 1
else:
M = gdate[1]
Y = gdate[0]
D = gdate[2] + (gdate[3] / 24.0) + (gdate[4] / 1440.0) + (gdate[5] / 86400.0)
A = math.floor(Y/100.0)
RV = math.floor(365.25*(Y+4716.0)) + math.floor(30.6001*(M+1.0))
return RV + D + (2.0-A+math.floor(A/4.0)) - 1524.5

Google open sources Gears

Google has open sourced it's web plugin Gears under a modified BSD license. Normally I wouldn't comment on something like this because it seems unrelated to what I'm doing with EarthBrowser. However I believe that it could be very important to the future direction of EarthBrowser. A web plugin that supports all major browsers on all major platforms is a *very* large project, one I would never attempt myself. I am kind of in shock that Google would make it so easy for others to make web plugins by giving this away under such a permissive license.

A really long time ago, way back when in the days of Netscape before Internet Explorer even came around, I had a version of EarthBrowser working as a web plugin. It had too many problems with memory limits on the old MacOS 7 and 8 so I canned the project and went with a desktop app. So now there is an open source web plugin code base that I can use to port my OpenGL version of EarthBrowser right into a website. I probably won't tackle that particular project until next year, but it is good to know that it is now possible.

I am very impressed with the release of this code, this is such a different way of doing business. I don't see any benefit for them in doing this, but there isn't any harm either. Way to share knowledge Google!

KML to JSKML translator now available

It's now available at the JSKML Site run though the Google App Engine.

I've created a KML parser that will transform a KML document into the JSKML format, or alternately a JSON formatted JSKML document if that is what you require. It's a simple copy and paste translator similar to Dean Edwards excellent Javascript Packer.

It currently works on the KML 2.2 standard and could use a little optimization but it is functional and easy to use. If you give it a try and find an error, please let me know.

jskml: Javascript KML Dialect

KML data structures need to be represented in other formats than just XML. With virtual globes moving into the web browser, the need for an alternate representation that does not require parsing to go from XML text into Javascript objects is an important step, in my opinion, in simplifying web based scripting of online mapping.

I have created a simple static website describing the new dialect at:
http://www.jskml.org.

I used Google App Engine and the Django framework to create this site. I've got another exciting app or two planned for deployment using this platform and this website was a good way for me to orient myself as well as put out a format that I feel should be supported.

Thoughts on the Google earth plugin API

Good job Google earth/maps team.

While it feels like they rushed the introduction of the earth plugin a bit, leaving pretty spotty documentation of the API and only a Windows version, it is indeed a great first step. Putting javascript tendrils deep into the control structure of the plugin was inspired and will be transformative.

However, the programmer in me can't help but be a little offended by the size and verbosity of the interface. Am I to understand that the very first example of creating a placemark is what will be needed for such a simple task?

var placemark = ge.createPlacemark('');
placemark.setName("You are at Google");
ge.getFeatures().appendChild(placemark);

// Create style map for placemark
var normal = ge.createIcon('');
normal.setHref('http://maps.google.com/mapfiles/kml/paddle/red-circle.png');
var iconNormal = ge.createStyle('');
iconNormal.getIconStyle().setIcon(normal);
var highlight = ge.createIcon('');
highlight.setHref('http://maps.google.com/mapfiles/kml/paddle/red-circle.png');
var iconHighlight = ge.createStyle('');
iconHighlight.getIconStyle().setIcon(highlight);
var styleMap = ge.createStyleMap('');
styleMap.setNormalStyle(iconNormal);
styleMap.setHighlightStyle(iconHighlight);
placemark.setStyleSelector(styleMap);

// Create point
var la = ge.getView().copyAsLookAt(ge.ALTITUDE_RELATIVE_TO_GROUND);
var point = ge.createPoint('');
point.setLatitude(la.getLatitude());
point.setLongitude(la.getLongitude());
placemark.setGeometry(point);


Admittedly it uses the super-annoying StyleMap which I feel should be abolished. Don't you think it is too much to ask to perform this kind of operation for every placemark? I suppose someone could create a wrapper library for this to simplify common tasks.

How about implementing this in your API instead:
ge.addPlacemark({
name:'You are at Google',
Style:{IconStyle:{Icon:{href:'http://maps.google.com/mapfiles/kml/paddle/red-circle.png'}}},
Point:{coordinates:{lon,lat,alt}}
});


Could the maps/earth team create the nicer interface wrapper?

EarthBrowser is Adobe site of the day, Google talk

I don't have the marketing megaphone that a Google has but EarthBrowser is starting to get a little attention in the Flash world. I was just notified today that earthbrowser.com was selected as the Flash site of the day. There was also a nice article recently on RIApedia.com titled EarthBrowser - 3D AIR App in Flash.

Google, via Michael Weiss-Malik, has invited me to come down and deliver a presentation about EarthBrowser, KML and whatever else I want to talk about. I guess it will be something like the Google Tech Talks where they make a YouTube video of the presentation. I've been consolidating things on version 3 for the past month so I haven't set a date yet but I'm pretty sure it will be mid July if that is available for them. Hopefully those guys aren't too miffed about my KML criticisms, or my out of date Google Earth criticisms. Perhaps I should bring a rotten tomato shield.

I've got a little project I'm hoping to unveil at or before the talk, but I'll leave everyone in suspense about what that could be...

Cyclone Nargis and GDACS

I've added a few new datasets to EarthBrowser's "Featured External Layers", which is below the main dataset element in the EarthBrowser control window.

I'm temporarily putting in a high resolution MODIS overlay of Cyclone Nargis from earthobservatory.nasa.gov. It's a really large image so be patient, it takes a little while to download. Due to a bug in Flash for large images scaled to be small, it doesn't look very good far away, but looks better as you zoom in. Hopefully they've got a fix for this in the works.



I've also added the Global Disaster Alert and Coordination System kml dataset which is updated with real-time information for ongoing disasters and recovery around the globe. To view the information for each disaster, you have to navigate through the list of elements in the control window, I wish they would put in placemarks to view the great information they have more easily.

Finally, the Europe Media Monitor layer is a news aggregation service that plots global news stories on a map and provides an overview and link to the geo-located story.

I'm also hoping to have an update out later this week with a timezone fix for sunrise/sunsets and also a global grid overlay feature.

EarthBrowser 3.0, 5 days in

Version 3 is doing very well over the past 5 days. It's selling better than I'd hoped for, the django based system I am using for the main website and for the separate data server have held up incredibly well with just a few hiccups. Amazon S3 really helps me to take the load off of my servers. I've got a handle on the tech support emails over the weekend, there are still a lot left however. I try to answer each and every person with a question or problem with a personal message. I think that kind of respect and care for each customer has really helped the business over the years. My goal is to have no unhappy customers, if I can't fix your problem or you are still not satisfied, you get a refund, it's pretty simple.

Thanks for the mention James, Mickey, Lxnyce and Bull.

Some people are wondering why would they should support EarthBrowser as shareware when they can get Google Earth, Microsoft's Virtual Earth and NASA WorldWind for free. Well you get EarthBrowser for free too, you are just reminded to help support the future development of the shareware if you like it enough to use it. Google Earth is great but it isn't your computer's operating system, you CAN use more than one virtual globe at the same time.

EarthBrowser may not have 2 inch resolution datasets, but the weather layers really blow away anything the other globes offer, in fact the weather forecast layers blow away most of what I've seen from the major weather providers offer. I'm talking with CustomWeather to see if we can do some sort of exchange of data for perhaps exclusive use of EarthBrowser on their website. I think that would really make them stand out from their competitors.

KML is great! New datasets are being added to EarthBrowser all the time, if you only know where to find them. Today I noticed from one of my favorite blogs Frank Taylor's Google Earth Blog that there is a new dataset available from NASA showing the total electron count in the earth's ionosphere. I like it so much I think I'll add it to the Featured Datasets in EarthBrowser. The red areas indicate a large concentration of electrons which may cause problems with communications. It is neat to see that the electrons build up on the daytime side of the earth and disperse shortly after darknes.



If you want to see the animated link of the ionosphere for the past 24 hours in EarthBrowser just drag this link onto the EarthBrowser window. Or if you are reading this blog with EarthBrowser's embedded web-browser, just click on the link. There is also a light weight version of this file that just shows the current condition.

EarthBrowser 3.0


EarthBrowser 3.0


Finally, it's out. Thank you to all of my wonderful supporters!!!

I transferred over the domain name to the development server and within about 20 minutes VersionTracker picked it up and I'm getting sales already.

Steve Wozniak was the 11th person to register version 3. He's been great to me and has bought several site licenses for schools. Maybe someday I'll be able to talk with the guy...

I have to give a tip of my hat to the Papervision 3D guys. They were my initial inspiration for the flash version, and although I wound up writing my own specialized rendering code, they deserve a lot of credit for what they have done! I'll go into details about how I did some things in flash in future posts, it has never been easy or fast to do software rendering. I'll also talk about some of my plans for the future.

Right now I'm sipping on a Paulaner Salvator Dopple Bock and basking in the euphoria of 4.5 years of hard work coming to fruition.

EarthBrowser 3.0 goes live tomorrow

Hopefully people will like it.

It's shareware, which means you can use it for free for as long as you like. However, I'm funding it out of my own pocket, which is pretty much empty at this point. So if you want all the features and don't want to be annoyed by reminders to register please pay the modest fee and help me to make it better and better. Upgrades discounted for current users of course. Oh, by the way, registered users will be able to embed EarthBrowser with their own content on their personal websites within the next several weeks.



I just wanted to say thank you to everyone who has been so encouraging to me over the past few years; my wife, children and friends. I couldn't have done it without you.

Do I seem frustrated and bitter?

I was just called out on the tone of my blog posts by someone I've known and respected for a long time. He said that he was a little surprised by my writing after reading my blog for the first time. I seemed bitter and frustrated, perhaps mostly at Google, and that isn't how he knows me. I guess I'm a little bitter, Google pretty much put me out of business years ago by releasing Google Earth for free. Hopefully EarthBrowser 3.0 will attract enough customers to keep my family stocked up on food, diapers and other necessities.

I have taken a confrontational approach to many of my posts, some of this tone is conscious, some isn't. I actually try to be a little controversial and opinionated on the blog because I'm just some joe-schmo and nobody wants to read some random guy's opinions that are mushy and congenial. That's not exciting or even interesting.

Unfortunately when writing in the blog some of my gigantic ego shows through which generally wouldn't happen in a conversation with me. I think that most programmers have really big egos, but mostly about their own coding abilities. In a self-preservation kind of way, I have to think that I'm a good programmer to tackle such a large problem by myself. I think that is just the nature of programming, no confidence = no code.

That said, I'm going to try to tone it down. Sorry libKML guys, hope I haven't offended anyone, I realize that it is just an alpha version.

KML, libkml and the "standard" mistake

Passing off KML to the OGC so it could become a "standard" was a big mistake for Google.

I consider myself well versed in the KML format since I just implemented most of it's features, and found them to be needing much more in the way of styling. KML will now change at a glacial rate due to the standards process, right when it needs to change the most! Google Earth's feature set will now become dictated by an outside entity, with their input of course, but that's no way to develop software! Why would they cripple Google Earth like that?

Also libkml has been released and it was exactly what I thought it would be, a glorified xml validation script for the kml dialect. I predict that no significant software will choose to link that library in.

I have to say the lamest thing about KML is the whole Style/StyleMap tag collection that enables one to set a separate style on an icon for mouse-over events. It's a great way to have a non-standardized interface since everyone rolls their own mouse-over effect for each placemark style!

I've implemented a few of my own extensions to the KML format which I will go into detail about later. They are mostly aimed at visibility and styling extensions. One of the most useful extensions is the tag which allows one to control the visibility of a Feature element (Placemark or GroundOverlay) globally based on camera elevation. This is much easier than setting up one of those elements, especially for a single placemark.

EarthBrowser 3.0 Imminent

EarthBrowser 3.0 is currently in beta testing and I think that it might live up to my prediction to revolutionize virtual globes. It should be released within the next two weeks.



Floundering In The Past

I have been working on version 3 of EarthBrowser since 2004 and it is finally coming to fruition. Up until about a year ago, I was still working on a version that was based on OpenGL with a Python scripting engine. It was basically a new platform that would do seamless version updates, enable users to extend the interface programmatically, do extremely fast raster and vector map projections on multi-gigabyte data files using JPEG-2000 incremental decompression. Use a hexagonal dataset grid to feed the fragment shader based clipmap engine for smooth panning around the poles with no perspective distortion. I was also downloading, pan-sharpening and color-space correcting the Landsat 15m dataset. Bit-torrent distributed datasets were integrated, relief mapping and atmospheric diffusion were supported. It really is a masterpiece, but then Google Earth was given away for free and sales of version 2 began to dry up as I was digging myself deeper and deeper.



The Turning Point

Then along came Modest Maps which introduced me to Flash programming. Once again plunging into yet another new technology, I decided to make a quick sliding map with a few datasets for people to put on their websites for free advertising. Then I saw Papervision3D and realized that I could do a globe. It was a little too slow for my needs so I ported my C++ game engine kernel over to Flash. I kept adding features expecting to hit the limit of what was possible with Flash and I never did. Around June I put the OpenGL version on the back burner and began working full time on a web version of EarthBrowser.


Unexpected Windfall

This February Adobe released Adobe AIR which enabled me to bring my EarthBrowser back to the desktop. AIR has some *really* nice features that make EarthBrowser much more powerful than I imagined it could be in my last post. There is an integrated web browser, right within EarthBrowser 3.0 now. That is huge and you won't really understand how easy it makes things until you browse some geo-websites and drag and drop KML links right into your placemarks folder or look at the Wikipedia page for a city or country.



Weather Datasets

There are a lot of other nice features that you won't see in Google Earth or Microsoft's Virtual Earth. I've been creating a lot of real-time datasets generated from the NOAA Forecast Models to give regions of rainfall, snowfall, humidity, temperature and many other measurements which are all animated across the globe with an intuitive time slider. Continental US doppler radar, earthquakes, volcanoes, webcams and many more datasets are all there and animated too.



Finally: KML Integration

KML support in EarthBrowser 3.0 is really nice and intuitive. There is a Panarimio KML file that allows you to see pictures from all over the world as you zoom in closer. You can download a KML or KMZ file directly within the embedded browser or drag and drop it from your desktop. EarthBrowser even has some extensions to the KML format that I felt were missing and greatly enhance the expressiveness of the format. But I'll save that for another post.



KML Mashup Tool

EarthBrowser 3.0 has really been designed to be a KML authoring and mashup tool. If you want to save a single feature from a dataset, just drag a placemark icon from the globe right into your placemarks folder and it will make a copy. You can drag out any combination of items in your placemark folder onto a text editor to make a custom KML mashup file to post it on your own website or share it with your friends. Version 3.1 will extend EarthBrowser from your desktop to your website. It will be easy since it is based on Flash technology. A simple and seamless way of creating and distributing your personal or corporate geospatial content.


I'm Not a Machine, Or Am I?

Is it possible for one man to compete with Google and Microsoft? Not really, and I'm not trying to. I want to make EarthBrowser an excellent tool for education, weather watching and KML authoring and have it be just enjoyable to use. Google and Microsoft are working hard to... hmmm... put buildings in... add more resolution... see star texture tiles and some other stuff. It takes a team of coders and a multi-billion dollar company to give this kind of software away for free. That's why I have to charge for it. I've spent countless sleepless nights and many evenings and weekends away from my family. I've gone into debt while sales of version 2 have dropped to almost nothing, trying desperately to get this new version done. I really have to thank my wife and children for their patience in allowing me to pursue the dream of owning my own business making virtual globes. Once sales pick up again with version 3, crossing fingers, I can focus on adding even more great features, but I'll talk about those later.

EarthBrowser 3.0 to be released soon

It's been hard keeping quiet about it for so many months, I'm really excited about all the great new features.

Some of the major new features are:
- Supports 90% of KML
- US Doppler radar
- Rain/Snow/Temperature forecasts

Version 3 is not just another 3d globe, but will revolutionize virtual globes for reason's that will be obvious when you first run it.

If you are a customer and would like to participate in the Beta program, please drop me an email and state any relevant testing experience (not necessarily required, but helpful).

Here is a small preview:


That's all for now.
