Grass is very useful tool for pre processing of imagery. I want to use the i.atcorr module separately. Will it be possible? I have compiled using .cpp files (AerosolConcentration.cpp, AerosolModel.cpp, Altitude.cpp, AtmosModel.cpp, etc) given but its asking grass functions to be declared. I dont want to use entire grass, only i.atcorr is required. How can i build that single module? Please suggest.

Yes, you can use GRASS GIS completely in a batch job. See
http://grasswiki.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly
It is possible to launch your i.atcorr job via shell script as well as via Python. Essentially just some environmental variables need to be declared.

for this grass needs to be installed.but i dont want to install and use just the modules. is it possible. Commented Jun 12, 2014 at 9:18

1Yes. The modules + libraries are GRASS GIS! :-) It is modular. So you can just extract the package and use the i.atcorr binary and the following libraries: libgrass_raster, libgrass_gis, libgrass_btree2, libgrass_datetime since i.atcorr depends on that and the start script. That reduces it to 2MB or so (at least that's the size on my Linux box).– markusNCommented Jun 12, 2014 at 20:44

may i know where should i copy the libraries? in c:/osgeo4w?directly can i create project in visualstudio and use the binaries or through msys i have to do. Commented Oct 22, 2014 at 9:57

1I would not copy them but rather tell visualstudio the path to the libraries...– markusNCommented Oct 23, 2014 at 7:12
