Contents

This publication contains geospatial information about the glacial geomorphology of central mainland Nunavut between 60˚ and 68˚N and between 100˚ and 108oW, and released as Geological Survey of Canada Open File 8915 (version 2022). The geospatial information includes field datasets provided in an ArcGIS 10.X gdb and in shapefile format. Tables and lists maps are provided in word and excel format. The compiled data has been integrated into an ESRI geodatabase (OF8915.gdb) that follows the different standards and classification of the Geological Survey of Canada’s Surficial Data Model v.2.4 (SDM) - a science language for surficial geology maps designed to produce standardized digital data sets with a structured database (Deblonde et al., 2019). The uniformization process involved populating the fields of the standard SDM shapefiles and attribute tables with the information provided from each individual sources. Additional information regarding stations, samples and ice-flow directions (including the aforementioned adjustments) were also added to the Notes field of each shapefile. Note that for generalisation, data that is labelled as striations in the F_SUBSET_FID field of the F_PLOW table include all types of small-scale erosional indicators suck as striae, chatter marks, grooves, rat tails, crescentric gouges, nail heads, etc. Shapefile and table (.dbf) versions of the data are also provided as simplified SDM compliant shapefiles (iceflow.shp, samples.shp and stations.shp):
