Several stages were necessary to create, acquire and prepare the data needed for the drape procedures and glacial topography analysis.  These initial stages constituted most of the project where the first step was to digitize a glacial geological map of Southern Alberta - compiled from past and recent glacial research studies, air photography interpretation, old geological survey data, and topographical maps - using ArcInfo 8.0.1.  Digitizing was time-consuming process that took almost three months to complete - more than two thirds of the project.

The second step was to process and put together a DEM of the corresponding Alberta area using ER Mapper.  Once the digitized coverage and DEM were complete, both were imported into IDRISI 3.2 where the data underwent final processing and basic Boolean analysis.  IDRISI 3.2 was chosen to perform our end analysis as it is raster based, thus more compatible with the DEM and for representing continuous field data – the nature of the many glacial landforms and soil distribution
