Access Constraints None
Use Constraints Spatial Resolution. Use of this digital geologic map should not
violate the spatial resolution of the data. The Porcupine Wash
geologic map and database was developed using digital orthophotograph
quarter quadrangles (DOQQs) as a base. DOQQs have a pixel resolution
of 1 m and are accurate to a scale of 1:12,000 (1 in = 1,000 ft). Any
