Geologic Map Finalization Guidelines

1. GIS Geologic Map Finalization:“overview of layers that should be getting close to final” June 2012, Planetary Mappers Meeting

2. Original ArcMap Geologic GIS Project -generated by USGS for mapper GeoDatabase – older projects may have a different extension Example used: Tooting Crater, Mars, 1:200k, Peter J. Mouginis-Mark, University of Hawaii Submitted for publication

3. Layers you should have GIS Raster Data Includes the USGS-created (or other) base map Include the MOLA DEM and shaded relief All high-resolution datasets used while mapping should be excluded, down sampled, or included as figures, footprint files, or supplemental data

4. Layers you should have GIS vector features (near final) Contacts/Linear Features (lines) Contacts should be snapped to other contacts Attributes defined in the table and displayed with unique symbology Symbology closely follow the FGDC Cartographic Standards Structural Layers (lines) Channels, crest of crater rim Symbology also follows FGDC Location or Point Features Uniquely attributed and symbolized Labeled if necessary Sized so they can be seen at the printable map scale

5. Layers you should have GIS vector features (near final) Geologic Units building polygons is an iterative process. As your map progresses, it is a good idea to have been testing unit (polygon) creation several times.

6. Layers you should have Contacts/Linear Features (lines)

7. Layers you should have Structural Layers (lines)

8. Layers you should have Location or Point Features, e.g. secondary craters

9. Layers you should have Overlay polygons, e.g. crater clusters

10. Layers you should have Overlay polygons, e.g. ejectafacies

11. Layers you should have Overlay polygons, e.g. NoData coverage

12. Goal: layers to build Geologic Units
