Relationship between files, if important: These all make up a shape file that can be opened in ArcGIS or QGIS 3. Additional related data collected that was not included in the current data package: This map was produced from the NASA MESSENGER image: EN0261054374M captured by the MDIS camera, the image can be found on: https://pds-imaging.jpl.nasa.gov/volumes/mess.html or https://ode.rsl.wustl.edu/mercury/index.aspx 4. Are there multiple versions of the dataset? no METHODOLOGICAL INFORMATION This map was produced using the USGS standard guidelines for planetary mapping: https://planetarymapping.wr.usgs.gov/Page/view/Guidelines Instrument- or software-specific information needed to interpret the data: The Map was produced using ESRI ArcGIS 10.8 And produced by David L. Pegg 3. Variable List: Cr1 – Crater Class 1 (oldest) Cr2 – Crater Class 2 (intermediate age) Cr3 – Crater Class 3 (youngest) CfHm – Craer floor hummocky/volcanic vent CfSm – Crater Floor Smooth PlIc – Intercrater plains PlSm – Smooth Volcanic plains The Variables can automatically be symbolised in ArcGIS using the .lyr file
