I am trying to intersect two shape files, one is a vector of .5 x.5 degree rectangles, the other is a vector of 20 x 10 degree rectangles.
I want the ID values of the 20 x 10 degree polygons to be carried over to the .5 x .5 degree polygons which are contained within the larger shapes.
The intersection produces what looks like the product I want for the whole globe, however when saving this I get the following error:
Feature creation error (OGR error: Attempt to write non-polygon (LINESTRING) geometry to POLYGON type shapefile.)
AND half of the output is successfully saved, but not the remainder (see image).
