File: McNeil_2021_Mound_Shapefiles.zip
Description: This .zip file contains a shapefile that can be imported into a GIS environment. The shapefile attribute table contains information pertaining to the mounds. All values are given to 6 decimal places regardless of original precision, as this is the raw data captured in ArcGIS.

Fields and Definitions in Attribute Table:
OBJECTID: unique numerical identification of each mound, in the order in which they were digitised between November 2019 and February 2020.
Zone: numerical value between 1 and 3 describing the broad geographic location of each mound, see Fig. 4 for a cartographic representation.
Type: text describing the mound in 6 different classes: ?hill?, ?mesa?, ?compound?, ?clust_hill?, ?clust_mesa?, ?clust_mixed?. See manuscript for definitions of these classes.
Lat: latitude of geographic centre of mound.
Lon: longitude of geographic centre of mound.
Peri_m: total length of perimeter of mound polygon, in m.
Area_m: total area of enclosed mound polygon, in m2.
H_MOLA_m: height of the mound in metres, derived from MOLA shots.
H_HRSC_m: height of the mound in metres, derived from the HRSC DTM.
P_MOLA_m: mean height of the plains surrounding the mound in metres from MOLA.
P_HRSC_m: mean height of the plains surrounding the mound in metres from HRSC.
