I am trying to count my datapoints inside different polygons, but it gives an error about my shapefile saying:
No spatial index exists for points layer, performance will be severely degraded
Feature (131) from “Geology Shapefile” has invalid geometry. Please fix the geometry or change the Processing setting to the “Ignore invalid input features” option.
Execution failed after 0.95 seconds
Does anybody know how I can fix this error?
Please fix the geometry
(= solution by @Mayo) orchange the Processing setting to the “Ignore invalid input features” option.
