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.
