snap_points_to_mask_raster.py - snapped points are not inside the mask raster, they are on the edge

[Shawn Laffan]

Using the polygon feature class results in points that lie on the edge of the mask raster. These then cause problems with the path distance analyses.

[Shawn Laffan]

Solution is to snap them to an inner raster (for which the edge is one cell inwards).

[Shawn Laffan]

Resolved by avoidance.
