Description: The land cover classification of Tuktut Nogait National Park, NWT (69 N, 122 W) is a thematic map produced by Parks Canada Agency (Western Arctic Field Unit) and the NWT Centre for Remote Sensing from satellite imagery. The land cover / vegetation classes were mapped from digital, multispectral Landsat 5 Thematic Mapper (TM) image data. Parts of three scenes were used to cover the park area: 56-11 and 56-12 from 29 June 1992 and 54-12 from 2 July 1998. The land cover classes consist of vegetation classes (such as wet sedge meadow and dry tundra) and non-vegetated surface types (such as sand/gravel and water). Classification was performed using computerized supervised classification techniques on the digital multispectral bands, with unsupervised classification techniques used for some non-vegetated classes, and some manual editing. Field work by Parks Canada staff provided information to match the spectral response on the imagery ("colours") to vegetation and land cover types. The classification data covers most of Tuktut Nogait National Park and an area extending 6 km or more beyond the park border. UTM 10 NAD83 projection. 25-m pixel raster data. Recommended scale: 1:75,000 to 1:500,000.
