Base Features hydrography polygons are classified according to valid hydrography feature types, and each feature type contains attributes with valid value domains for feature type, feature code, and name. Feature typing and attribution is complete for all hydrography polygons in Alberta. At the time of capture of source, audit processes were enabled that assured the accuracy of attributes as defined by the Base Features Hydrography Data Specifications. The update scale for Base Hydrography update shall be no less than 1:2,000-1:3,000. Based on the use of digital colour imagery with 0.5 metre resolution. Feature capture or update shall achieve a positional accuracy of 5 metres (90% CI) 5 metres Base Features hydrography polygons are classified according to valid hydrography feature types, and each feature type contains attributes with valid value domains for feature type, feature code, and name. Feature typing and attribution is complete for all hydrography polygons in Alberta. Base Hydrography Update: this process creates the Single Line Network, HydroPolygons and HydroPoints. The update is based on existing Base Features Hydrography data, currently available orthophotos, currently available SPOT imagery and supplementary data such as Wet Areas Mapping and LiDAR. Proper naming of features in the Single Line Network, Hydropolygons and Hydropoints occur. Single line representation of the hydropolygons is added to the Single Line Network coverage as well. 2019-05-27T00:00:00 Alberta Environment and Parks, Government of Alberta Provincial Geospatial Centre 7804220712
