Polygon Polygon Intersection

[kurt-rhee]

Hello,

I am looking for a library that can do many polygon-polygon intersections via the GPU, as far as I could tell cuspatial does not do polygon-polygon intersection, but I wanted to ask first just to be sure.

Thank you in advance!

Hi @kurt-rhee - thanks for checking out cuSpatial!

We can do the binary intersects operation between polygons, but if you're looking for the output geometry intersection between polygons then right now that's not supported - you're correct.

If your polygons don't have holes/you don't expect multipolygons you may be able to piece something together using the LineString Intersection API, following something like:

• Extract the boundaries from your polygons and convert them to into LineStrings
• Perform intersection operation
• Combine the outputted LineStrings back into a polygon

Awesome thank you for the quick response!
