I am attempting to georeference this parcel map from a local assessor's office.
In doing so, I am using the georeferencer in QGIS 3.4.
I am using the DMS coordinates on the image to reference the corners of the parcels. The format that QGIS requires is as follows: (dd mm ss.ss
).
I think the corners on the parcel map are as follows:
Top left corner: N0° 13' 08"E, N89° 52' 06"E
Top right corner: S0° 15' 08"W, N89° 52' 06"E
Bottom left corner: N0° 13' 08"E, S89° 52' 52"
Bottom right corner: S0° 15' 08"W, S89° 52' 52"
I reference the parcel as follows:
Top left corner: X/East = 00 13 08.00, Y/North = 89 52 06.00
Top right corner: X/East = 00 15 08.00, Y/North = 89 52 06.00
Bottom left corner: X/East = 00 13 08.00, Y/North = 89 52 52.00
Bottom right corner: X/East = 00 15 08.00, Y/North = 89 52 52.00
I set the target SRS to EPSG: 4326
When I finish georeferencing the image, I expect it to be in Cochise County, AZ, but it is way off.
I asked the assessor what the image's CRS is and he said, "The mapping system used by the county assessor is based on the U. S. Public Land Survey System (PLSS). This system uses a section, township and range which is tied to the Gila & Salt River Base & Meridian (GSBM)."
How can I georeference this image? Where am I going wrong, or what more information do I need?
