Comments:Survey data is in two databases: Mag and Rad. Line spacing in the NW corner is 500m. Mag data was collected using the GPS clock and the rad data was collected using the rad console clock which was slightly different from the mag clock by a millisecond or so. The GPS clock was the more accurate one. XY data differ slightly between mag and rad databases.
