I am trying to define a map using v.in.ascii. The map is basically a few squares in the northern atlantic ocean defined in Lat lon, So I have made this input file:
MAP NAME: hav MAP DATE: 2007 VERTI: B 5 1 -12 81 3 81 3 73.5 -12 73.5 -12 81 1 26 B 5 1 -12 71 3 71 3 73.5 -12 73.5 -12 71 1 38 B 5 1 -7 71 3 71 3 68 -7 68 -7 71 1 36 B 5 1 -7 71 -12 71 -12 68 -7 68 -7 71 1 35 and then I save it at Havomrder.txt and import it using v.in.ascii --o input=Havomrder.txt output=hav fs=' ' format=standard and get the following messages: Building topology ... 4 primitives registered Building areas: 100% 2 areas built 2 isles built Attaching islands: 100% Attaching centroids: 100% Topology was built. Number of nodes : 3 Number of primitives: 4 Number of points : 0 Number of lines : 0 Number of boundaries: 4 Number of centroids : 0 Number of areas : 2 Number of isles : 2 Number of incorrect boundaries : 2 Number of areas without centroid : 2 I thought I should have gotten 4 areas build and no isles and I do not understand why I get the two last lines. Does it matter if I define the areas CW or CCW? I have tried to remove the .5 and to save the file both as a dos and unix file without any help. I am running grass 6.2.2 on a Cygwin / win Xp system. When displaying the file (d.vect hav), I get lines that looks reasonable, but no vertexes or centroides, when using d.what.vect, I get feature type Area but I never get any id when clicking in the uppermost largest square and in the other three, I get (seemingly) randomly categories 26, 38 and 36 wiht feature type Boundary... I cannot see from the help file for v.in.ascii what may be wrong. thanks Morten Sickel _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
