Mars 25M Geologic Map SIM-1083 GIS Renovation (1978)
The original Geologic Map of Mars by David H. Scott and Michael H. Carr (1978) was created from images acquired during the Mariner 9 television experiment. The equatorial region, which lies between latitudes 65 south and 65 north, was mapped at 1:25,000,000 scale. The poles, areas above and below 60 degrees latitude, were mapped at approximately 1:5,000,000 scale. To bring this benchmark map into current mapping context it was digitized and renovated by Tenielle Gaither using the semi-controlled THEMIS Daytime IR 100 m/pixel basemap. This was completed by georeferencing each map to the new base and adjusting the existing geologic unit interpretations based on the higher resolution imagery. The three datasets were then merged to create one global dataset to be used in a variety of GIS applications.

- Process Description
The poles, areas above and below 60 degrees latitude, were mapped at approximately 1:5, 000, 000 scale. To bring this benchmark map into current mapping context it was digitized and renovated by Tenielle Gaither using the semi-controlled THEMIS Daytime IR 100 m/pixel basemap.
