AtGLas is a Portable Atlas coded with C++ using OpenGL, DevIL, audiere and ffmpeg. Runs Ok on Linux, needs work on Windows, not tested on Mac. Needs code cleaning, internationalization (its in spanish) and more content
It could be a great project, but it lacks enough data. As developers say, they need to obtain more royalty-free maps and imaginery. I understand that was the main reason for this project being abandoned. Despite this, the project could be useful for people from Colombia, Venezuela and Brazil, the only currently supported countries.
