When I first ran analyses and created maps for this project it was about
18 months ago, and my notes are not as complete as I would wish.
I have an ASCII file with 5 rows and 3 columns: easting, northing, and
label. I ran that through v.in.ascii (after setting the region
appropriately) and it worked:
WARNING: Vector map <proj_pts> already exists and will be overwritten
Scanning input for column types...
Maximum input row length: 32
Maximum number of columns: 3
Minimum number of columns: 3
Column: 1 type: double
Column: 2 type: double
Column: 3 type: string length: 11
Importing points...
100%
Populating table...
v.in.ascii complete.
But, when I try to display this map GRASS tells me I cannot do so:
GRASS 6.5.svn (Oregon):~/grassdata/Oregon/beaver_lake > d.vect map=proj_pts
WARNING: Unable to display areas, topology not available
I also cannot disply it using the gui.
Since I'm not seeing what I'm not doing correctly I humbly ask for
assistance.
TIA,
Rich
