This tool may be used to update the Y_COORD/X_COORD fields according to the GEOMETRY (and Latitude/Longitude). This is necessary if the point geometries are changed e.g. in a GIS and therefore are not in the same position as Y_COORD/X_COORD would indicate. This function depends on an internal database trigger, which runs as soon as the point is moved and updates the Longitude/Latitude fields and also sets a flag in the data record. Aquabase then uses the flag to update the Y_COORD/X_COORD.
