Hi,
I have four simple rasters that I would like to polygonise:
1:
# # #
# #
# #
2:
# #
# #
# # #
3:
# #
# #
# # #
4:
# # #
# #
# #
It's the same shape, just rotated 90, 180, 270 degrees. The resulting polygons
for 1 and 2 are simple polygons without holes, where the results for 3 and 4
are polygons with a hole intersecting the exterior ring. Thus 3 and 4 results
in invalid geometries with self-intersection.
Is this the intended behavior of the polygoniser?
Regards, Casper
