The Base Hydrography Point Event layer contains hydrographic point features representing the locations of water or water related features captured through the 1:20000 Provincial Base Mapping Project, the 1:50000 Resource Access Mapping Program, the Alberta Vegetation Inventory Program and the Federal Government National Topographic Data Base 1:50000 mapping.
Base Hydrography Update Index depicts the extent of the current HUC 8 (Hydrologic Unit Code) watersheds completed in 2018-2021.
Base Waterbody Polygon Update is the Alberta Environment and Parks base hydrography polygon dataset, it is an updated of the Base Features Hydro Polygons in Southern Alberta from orthophoto and various sources of provincial base data.
The Base Hydrography Single Line Hydrography Network (SLNET) is the Alberta Environment and Parks base SLNET data set. It is an update of the Base Features HydroSLNET in Southern Alberta from orthophoto and various sources of provincial base data. It contains all captured single line representations of hydrographic features. In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file.
Province-wide spatial view showing licensed water sources (streams and lakes), under the Water Act, (current and historical), not captured (displayed) on TRIM base mapping (or Freshwater Atlas base mapping).
This data, also known as the Linear Highway Referencing System (LHRS), is used to locate events along the highway network. Three separate files make up the LHRS dataset: LHRS route is a spatial (GIS) representation of the highway network; LHRS Base Points divide the highway network into base sections with known driven distances; LHRS features points (composite listing) are additional described locations along the highway network. The location of events can be identified by a driven distance, along the LHRS route from a given LHRS Base point or feature point. *[GIS]: Geographic Information System *[LHRS]: Linear Highway Referencing System
Part of the Nova Scotia Topographic Database the Nova Scotia Hydrographic Network (Water Features) is updated and maintained from aerial photography. Lakes, Rivers, Islands and many other features are collected and networked into a seamless relation data base. Toponyms are included in the attribute table for named hydrographic features. Hydrographic feature codes and their descriptions are provided with the download in a NSTDB feature code table.
This cartographic quality series of 1:1 000 000 scale colour maps cover the provincial extent of Alberta. The primary provincial base map displays the Alberta Township System (ATS), major hydrographic features, municipalities, major roads, railways and select geoadministrative features (parks, reserves, etc.). In addition to the primary provincial base map, this series includes various themes that overlay the primary base map. The update of this map series is based on the provincial Base Features Access Update Program that has an approximate 5 year update cycle.
