In the past I have worked mainly with RASTER layers in GRASS and they
just worked (some how). Now I am working alot with vectors in GRASS.
For instance I have a region that was created througha v.in.ogr. Now
when I bring in the coresponding raster maps they are verry blocky
unless I view them from a far out zoom. My region settings areprojection: 0 (x,y)
zone: 0
north: 44.86371257
south: 44.67956501
west: -76.34802196
east: -76.08834984
nsres: 0.00920738
ewres: 0.01298361
rows: 20
cols: 20I created a DEM from contour lines (v.surf.rst) and the results are
undesireable due to the chopyness of the raster. for instance instead
of smooth DEM I have lakes that contain one or two raster cells. The
same area would contain MANY contour lines. CheersA quick explanantion of what I've done and how to increase the
resolution of the rasters in my project would be appreciated.
Increase the resolution in a lat/lon location to 1-arcsec with:
g.region res=00:00:01
(degree:min:sec)
then check the number of rows and columns you have. Set as needed, but
for a crisp display on the screen you will want to at least match the
screen resolution, ie 1000x1000 or so.
