Summary
This map sheet is one of a series covering that part of the surface of Mercury that was illuminated during the Mariner 10 encounters. Planimetric control is provided by photogrammetric triangulation using Mariner 10 pictures (Davies and Batson, 1975). Discrepancies between images in the base mosaic and computed control-point positions appear to be less than 5 km. No attempt was made to resolve discrepancies in feature positions on this sheet and those on the Kuiper (H-6) quadrangle to the north and the Bach (H-15) quadrangle to the south. The latter sheets were controlled by an earlier, more preliminary net.

Digitized 1:5,000,000-scale geologic map of the the Discovery quadrangle of Mercury. Originally mapped on Mariner 10 imagery the map was digitized as a GIS product in 1999. The polygon shapefile has been smoothed and transformed to align with the more current 2013 Messenger basemap. Then a polyline feature was created and attributed with contact type.
