This effort represents an attempt to build a complete index of Open Source / Free GIS related software projects. The effort has some way to go, especially for projects in languages other than English. The definition of GIS has been kept loose to encompass a broad range of projects which deal with spatial data.
If you know of other sites that should be listed please tell me about them. More importantly if I have made any errors in characterizing a project, let me know: bglewis<at>gmail.com.
жаль планеты там пока еще нет...
Есть много интересного, 3d земля, определение дислокации по IP/, траектории спутников, и другие инструменты и алгоритмы...
