The second part shows off the new multimedia annotations in the SDK, first we see the globe with two annotations, one has information about Mount Saint Helens, clicking view slides brings up a Java viewer box showing an image of Mount Saint Helens before it’s last major eruption, we then zoom in and pan around to see what it looks like now, by looking at fhe slide we can easily see the difference. Then zooming out to see the whole globe, the world map, compass, scalebar and finally placenames are turned off, and we zoom away into space. To begin we zoom in to Washington, it starts off as satellite imagery, Blue Marble NG, then as we get closer i-cubed and finally high resolution aerial imagery from the USGS, we pan around a bit then click on the World map to automatically zoom to Europe, by using the world map again we take a tour of the globe, first to South Africa, then China, Australia and finally back to the U.S. The first part of the video uses the basic build of the SDK, it shows placenames, a compass, scalebar and a clickable world map. I’ll put a short description of how I made the video at the bottom of this post, but be aware I used so FRAPS, so there are some dropped frames which makes the app’s look less smooth than they actually are. The bounding box is for limiting output size and data, and has to be expressed in Latitude/Longitude (decimal degrees).To follow up on my post about the new nightly builds of World Wind Java I have put together a video clip, also I didn’t mention it in the last post but the builds are version 0.6 of the SDK. They can be downloaded as GeoTIFF from the web interface. Greeness and Rainfall layers are available to public: ![]() Sample input data is not provided due to copyright restrictions, but you can try with your own GeoTIFF and DEM files. This is due to GDAL not already loaded when opening the window, so close the dialog and open it again, it will work. There is a small issue in GDAL loading so, if you open the application and browse for files, it can show no options. The Desktop Application is based on WorldWind Java SDK (already included as a jar) and on GDAL libraries. The application requires an OpenGL ES 2.0 capable device and has been tested on tablets even if it can work also on phones. You need the zip file called "wwtiles.zip" that must be copied (not extraced) in the root of your device SDCard, either if it is emulated by the phone or a physical SDCard (External memory).Īfter copying data, just open application and follow the instruction (the app will automatically get the cache from zip file and startup the environment). Desktop Application: The Android application can't work alone because it has developed to work offline. ![]()
