Hi guys!
I got a SHP 3d with countour line at 25m and using this,i had to create a dem;
I imported the shp using v.in.ogr and enabling the flag for 3d shp and this is
the v.info output:
[..]
Map Scale: 1:1
Map format: native
Type of Map: Vector (level: 2)
Number of points: 0 Number of areas: 0
Number of lines: 2918 Number of islands: 0
Number of boundaries: 0 Number of faces: 0
Number of centroids: 0 Number of kernels: 0
Map is 3D: 1
Number of dblinks: 1
[..]
The associated table got element like those one:
id | cat | id | igds_layer | eq_lvls | altitude
1 1 0 .... 5 100m (the value of the cl)
Doing a query on the vector map i noticed this anywhere:
map: 'cdl25m'
mapset: 'PERMANENT'
feature type: Line
length: 4008.907401
Line height: 0.000000 <== Is this ok with 3d file?
Then I started v.surf.rst with this vector (after setting the res to 20):
v.surf.rst input=cdl25m layer=0 dmin=0.5 elev=dem20 tension=90
But the raster output has got all cell with 0 altitude...what i am missing?
Thx
Luca
