LiDAR data was collected using LSI's proprietary Helix LiDAR system - Novatel GPS and SPANS inertial unit, coupled to a Riegl Q560 digital waveform ranging laser and mounted in a Cessna 185 aircraft. LiDAR was collected at 600m AGL, and a ground speed of 160km/h. Original data was in an ASCII XYZ coordinate format.

Lignes de courbes de niveau générés à partir des données LiDAR capturés par McElhanney Consulting Services Ltd (MCSL). Les courbes de niveau relient les points de même élévation pour le paysage visé par le projet.

The "Total Gross Drainage Areas of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing polygon features representing the maximum area that could contribute surface runoff (total gross drainage areas) for each gauging station of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. These polygons overlap as upstream land surfaces form part of multiple downstream gauging stations’ total gross drainage areas. Drainage area includes all land whose surface runoff contributes to the same drainage outlet or gauging station. Many gauging stations share the same headwaters, thus the overlapping areas (or polygons). The majority of the drainage areas in this dataset have shared areas.

The “Incremental Gross Drainage Areas of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the incremental gross drainage areas of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project area is subdivided by hydrometric gauging station. The maximum area that could contribute runoff to each station, less that of its upstream neighbour(s) is called an ‘incremental gross drainage area’.

The “Major Drainage Systems of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the three (3) major drainage system basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project area has been split according into which body of water it drains: the Arctic Ocean, Hudson Bay or Gulf of Mexico.

The "Effective Drainage Area of the AAFC Watersheds Project - 2013" dataset is a geospatial data layer containing polygon features representing the areas of the Agriculture and Agri-Food Canada's (AAFC) Watersheds Project that could, for the entire project areas, be expected to contribute to surface runoff under average runoff conditions.

The “Incremental Effective Drainage Areas of the AAFC Watersheds Project– 2013” dataset is a geospatial data layer containing polygon features representing the portions of each incremental gross drainage area of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project that could be expected to contribute to surface runoff under average runoff conditions. An ‘incremental gross drainage area’ is a hydrometric gauging station's drainage basin, less that of the next upstream gauging station(s)’. ‘Effective drainage’ occurs in areas that are expected to supply surface runoff in an average runoff.
