Notice that only points that are inside the data clip boundary have been
imported, and that a green border was created from the imported data.
The border is outside the red data clip boundary in some areas, and inside
the data clip boundary in other areas. This happened because points in
the point file that are outside the data clip boundary were excluded during
the import operation. The green border is formed by the points at the
outermost extents of the points that were imported.
