[FEATURE]: Add is_not_null_island check #603
Description
Is there an existing issue for this?
- I have searched the existing issues
Problem statement
Geospatial data columns often contain POINT(0 0) to indicate that no known position exists. We essentially have the is_null problem for point geometries/geographies.
Proposed Solution
Write a new (geo)check that tests if a column of points does/doesn't contain the null island.
