Viewshed, Fresnel zone and radio coverage prediction modules are presented on this web page. Modules are running on GRASS GIS software with support of CUDA. A prerequisite for running modules is a computer with installed CUDA enabled graphics card and Linux OS.

On this page you can find source code, installation manual, programmer's manual and other useful information for using or building parallel GRASS GIS CUDA modules. Please note, that this project is still in experimental phase and errors are possible. Any comment or feedback would be very welcome.
