Mercury 5M GIS Conversion v2
These polygons are beased on the original created 1:5M geologic maps for Mercury as published in the late 80's and early 90's as created by several authors. The original GIS conversion was completed in 1999 using older photomosaic bases as part of a larger digitization effort. To make this dataset more useful with modern data it has been smoothed (ArcGIS PAEK smoothing method with a tolerance of 10 km) and transformed (projective transformation) to align with the 2013 Messenger base map. Links used to transform the data are included with this documentation. A polyline feature class was then derived from the polygons and attributed with contact types. All datasets use the slightly smaller Mercury radius of 2439000 m rather than the Mercury 2000 radius of 2439700 m.
