The Alberta wall to wall land-cover (LC) polygon vector layer circa 2010 (ABMIw2wLCV2010), version 1.0, is a map describing the spatial distribution of LC across the province of Alberta for the reference year 2010. The map legend consists of 11 LC classes (see below), and the map itself (i.e., this feature class) consists of a mosaic of roughly a million non-overlapping polygons of various sizes, from half a hectare (ha) to thousands of ha. The minimum mapping unit (MMU, or minimum polygon size) is 0.5 ha for aquatic features and 2 ha for the rest, and the Minimum Mapping Width (MMW) is two Landsat pixels (60 m). The file format chosen for the ABw2wLCV2000 is ESRI file geodatabase (gdb), and the cartographic projection is Alberta 10 TM. The cartographic scale of reference (i.e., the scale at which the map would be printed if distributed in hardcopy) is 1:125,000. The target positional accuracy of polygon outlines is 0.5 mm at that scale, or 60 m on the ground. The overall thematic accuracy of the map is 75% with 11 classes, and 88% if these classes are grouped into 5 general classes.
