001570: The analysis option you selected requires a minimum of <value> points to be within the bounding polygon areas.

Description

Less than 30 point features fall within the bounding polygon areas you provided. Only the points within the bounding areas will be analyzed. As with many statistics, a minimum of 30 features is required to produce reliable results.

Solution

Unfortunately, if you do not have at least 30 points, this method is not appropriate for your data. With a minimum of 30 points, however, the solution here will often be to provide different, perhaps larger, bounding polygon areas.

Another option would be to provide a layer with a minimum of 30 aggregation polygons that overlay at least 30 of your points. When you provide aggregation polygons, analysis is performed on the point counts within each area.
