Description: In the fall of 2005, the Northwest Territories Department of Industry, Tourism and Investment (ITI), retained EcoDynamics Consulting to compile, digitize, and where possible, enhance the existing soil survey information covering over 4.3M ha of land in the southern Northwest Territories (Figure 1). The overall purpose of the project was to ensure that this existing map coverage is available in a digital form to support agricultural planning and management in the NWT. Funding for the project was from the Canada - NWT Agricultural Policy Framework Program (Agriculture and Agri-foods Canada) and the Government of the Northwest Territories (GNWT).The resulting digital map set provides soil and agricultural land capability information for over 4M ha of the southern Northwest Territories based on compilation of a variety of soil surveys conducted during the 1960s and 1970s. Digital versions of these historical paper maps were produced using various computer-based techniques including raster scanning, raster-to-vector conversion, georeferencing and conflation. Various soil and soil capability for agriculture attributes were then attached to each digital map polygon using the built-in database structure of ArcMap. Revised map legends and soil descriptions were also prepared based on current Canadian soil taxonomy and terminology. A reconnaissance level field program was also undertaken to gain familiarity with the soils of the study area and to assess the general reliability of the existing information.
