| Apr 25, 2018 at 14:12 | comment | added | Jon | Ah, I guess you're using shapely's intersects method. You could try int_gdf = gpd.sjoin(hulls_gdf, water_gdf, op='intersects'). | |
| Apr 25, 2018 at 14:06 | comment | added | Jon | What is the variable "polygons" in your script? I ask because you refer to the hulls as hulls_gdf but you write "polygons" in your code. How are you checking the CRS and what are the epsgs? If you type "hulls_gdf['geometry'][0]" does it plot the expected geometry of the first polygon in the gdf? (I'm assuming you're using an IDE) @user30184 If you intersect two geodataframes, you get a geodataframe as an output. Not clear if OP is intersecting geometries or geodataframes. | |
