Rather than use raster DTM maps I decided to use depth measurement points themselves.
The data look like this: lon,lat,depth 7709581.42,697951.64,24 7705545.87,698624.07,16 7709732.27,699488.73,27 7712090.79,699428.24,62 7716863.99,701238.89,32 7701540.85,698790.50,31 7713676.33,699192.82,58 7705283.41,697549.00,31 7705037.10,698489.22,16 The command I'm using is: d.vect map=lady_channel_sounding_points display=zcoor type=point zcolor=blue size=7 and the resulting map is attached. Perhaps I should make the computational region smaller to make individual values visible, but are the display and color values what they should be? The values are displayed in red, not blue. TIA, Rich
