[GRASS-user] conversion to fire simulation data set in the Grass GIS

[Thomas Adams]

Kalindu,

I do not see any lat/long coordinates. Do you have them in a separate file
by station ID. As Rich Shepard suggested, it is far best to have all the
data in a single file including the lat/long locations for the station IDs.
