This generator can be used to mask columns of latitude and longitude.
The Geo generator divides the globe into grids that are approximately 4.9 x 4.9 km. It then counts the number of points within each grid.
During data generation, each (latitude, longitude) pair is mapped to its grid.
If the grid contains a sufficient number of points to preserve privacy, then the generator returns a randomly chosen point in that grid.
If the grid does not contain enough points to preserve privacy, then the generator returns a random coordinate from the nearest grid that contains enough points.

From the value type dropdown, select whether this column contains a latitude value or a longitude value.
