#2324: v.to.rast: useless area warning on points-only maps
-------------------------+--------------------------------------------------
Reporter: neteler | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: Vector | Version: svn-releasebranch70
Keywords: v.to.rast | Platform: Unspecified
Cpu: Unspecified |
-------------------------+--------------------------------------------------
There is a small issue which confuses (new) users a lot:
{{{
# rasterizing a map with only points:
# GRASS 7.1.svn (nc_spm_08_grass7):~ >
v.info -t geodetic_pts | grep 'points\|areas'
points=29939
areas=0
# ... but there is an area related warning!:
v.to.rast input=geodetic_pts output=test use=attr attr=GDC_ID
WARNING: No areas selected from vector map <geodetic_pts>
Reading features...
100%
Writing raster map...
100%
Converted points/lines: 29939 of 29939
v.to.rast complete.
}}}
The issue is here:
{{{
vect2rast.c:
Points = Vect_new_line_struct();
if (use != USE_Z && use != USE_D && (ftype & GV_AREA)) {
if ((nareas = sort_areas(&Map, Points, field, cat_list)) == 0)
G_warning(_("No areas selected from vector map <%s>"),
vector_map);
}}}
but I don't know how to change the if() condition properly.
