Unusual Water Condition
Above left: SEE-IT locates a suspicious line of steep (vertical) water polygons (red circles), terminating at a geotile boundary (green lines). Only water polygons, errors, and geotile boundaries are drawn here for clarity.
Left: SEE-IT profile perpendicular to the suspicious line. Notice the 20m vertical blue line (water) (with no surrounding water).
Above: JSAF profile through part of the suspicious line. Note: The suspicious line is completely invisible on the JSAF GUI!
