[GRASS-user] help(r.walk and r.cost and ogr)

[Ricardo Rodríguez]

hello all, I'm developing a pywps geoprocess in calculating accessibility, I
saw a command called r.walk and r.cost not how viable is to use my project
as: composite, I would like to share their experiences with these
commands, downside
is that the input data are vector network "ogr" I recommend to process
attributes to network with their raster, or that would be the most
appropriate to make these calculations, I just need a basic procedure

 thanks for your answers and suggestions
