[GRASS-user] clear sky index interpolation

[Dylan Beaudette]

Hi,

Are you trying to generate a 2D raster map of interpolated values, or
a 3D 'volume' of interpolated values? If your input consists of
{lat,lon,kc}, then a 2D raster map is likely what you are after. In
that case, check out the v.surf.rst module.

Cheers,
Dylan
