Description Digital soil mapping (DSM) is a modern approach to soil mapping that combines geo-referenced soil observations with geo-referenced environmental layers to mathematical model soil variation across a landscape as a function of environmental conditions. These Ottawa digital soil maps describe soil property variation in the Ottawa region via a collection of raster datasets. For information on how these maps were generated, please see the “DSM Summary Description” document below

The Ottawa DSM layers are available as downloadable GeoTIFF files by following the links in the DSM Raster Directory or by clicking the links to the individual raster packages below. GeoTIFF files require spatial software to view correctly, such as ArcGIS or QGIS.

These layers can also be visualized online and analyzed via the ArcGIS REST service (and then click on your respective soil property for the direct rest service link) or by visiting the Ontario Soils Geohub.

For more information on the functionality of ArcGIS REST services, read the Ontario Web Raster Services User Guide. If you have questions about the data itself, please contact omafra.gis@ontario.ca

This is a georeferenced raster image of a printed paper map of the Ottawa, Ontario / Quebec region (Sheet No. 031G05), published in 1950. It is the fifth edition in a series of maps, which show both natural and man-made features such as relief, spot heights, administrative boundaries, secondary and side roads, railways, trails, wooded areas, waterways including lakes, rivers, streams and rapids, bridges, buildings, mills, power lines, terrain, and land formations. This map was published in 1950 and the information on the map is current as of 1948. Maps were produced by Natural Resources Canada (NRCan) and it's preceding agencies, in partnership with other government agencies. Please note: image / survey capture dates can span several years, and some details may have been updated later than others. Please consult individual map sheets for detailed production information, which can be found in the bottom left hand corner. Original maps were digitally scanned by McGill Libraries in partnership with Canadiana.org, and georeferencing for the maps was provided by the University of Toronto Libraries and Eastview Corporation.
