During the process of developing the Bathurst Caribou Range Plan the Tłįchǫ Government and Athabasca Denesọłiné First Nation generously agreed to share spatial data on the traditional knowledge of water crossing locations. Spatial data on caribou crossings also existed within the Prince of Wales Northern Heritage Centre’s database of archeological sites. This feature class represents these three merged datasets. Due to the sensitive nature of this water crossing data, exact geographic coordinates of each water crossing feature are not provided. Instead a subset 10km squared vector grid was created to define the current spatial extent for the merged datasets. Grid cells are attributed with the organizational contact information to direct interested parties to the appropriate points of contact for the dataset. The datasets being described within this feature class are shown without prejudice to identification of other water crossings. The datasets are considered incomplete as they are being added to and refined continuously; Water crossing features exist outside the spatial extent of this feature class. Detailed Methodology:To create a subset of grid cells to represent the spatial extent of contributed water crossing locations, geographic coordinates of the crossings were buffered by 15 kilometers and then spatially joined to a territory wide 10km by 10 km grid. Grid cells identified, thru the spatial join, to intersect the water crossing 15 km buffers, became the subset of grid cells representing the spatial extent of the water crossing datasets. Finally, the subset of grid cells was dissolved by contributing organisation into generalized polygons to facilitate reporting. Created: January 2020.

This data set represent fire perimeter outlines. Un-burnt islands are included in the fire perimeter as are small internal lakes.The overall data accuracy should be assumed to be at 1:250,000 scale. There are known data gaps in this data set, one should not assume that all fires have been recorded. That being said this record is the most complete currently available data set for fire perimeters in the NWT. Omission and accuracy errors are much more prevalent for the beginning of the data set, particularly for the 1965 to 1975 period. The data set was updated in 2006 using the NWT fire files and Landsat images dating back to the beginning of the Landsat record. During this update Landsat fire perimeters were on screen digitized to an accuracy of 1;250,000. Since 2008 the source of the fire perimeter has been recorded in the SOURCE attribute field. The sources are GPS, MODIS and Landsat. Where this information is recorded the accuracy of the perimeter can be assumed to be 1:250,000 for GPS, 1:1,000,000 for MODIS and 1:25,000 for Landsat.
