Hi grass users,
i'm trying to export a grass vector and generate a shapefile using
v.out.ogr. the vector contains 4 points and 6 boundaries each has its
own centroids.
the output shapefile contains 4 objects out of 10. WHY? How can I get
all the objects?
(i created the vector using v.patch from 2 separate vectors, one
containg 4 points and the other containing 6 boundaries + centroids).
Shapefiles can only hold one type of data (point, line, polygon) per
shapefile.
You can't export a grass vector with both points and areas to a single
shapefile. You'll have to do it in two passes to two different
files with
v.out.ogr and different "type=" parameters.
That is, it'll be as if you exported the data before having done the
v.patch.
