Title: Base Watersheds
Other Citation Details: The Base Watersheds is a collection of four integrated geospatial datasets: Hydrologically Corrected Filled Digital Elevation Model (DEM), Simplified Hydrography, Watersheds and Routes. Strahler Order coding has been applied to the Simplified Hydrography and the Watersheds. Hydrocoding has been applied to the Routes.
Description:
Abstract: This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The Base Watersheds data was created by re-working and post-processing the digital elevation data from the Alberta Provincial Digital Elevation Model, the digital hydrography data from the Base Stream and Flow Representation Lines, the Base Waterbody Polygons and the Base Hydrography Point Events and the digital boundaries of the ATS Version 4.1 Alberta Provincial Boundary. The digital elevation data was hydrologically corrected using simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons. The digital watersheds were created using the hydrologically corrected filled Alberta Provincial Digital Elevation Model data as a base and the simplified versions of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as pour points. The routes were created from the raw and simplified versions of the Base Stream and Flow Representation Lines using the names or the longest stream as the base. Strahler Order coding was applied to the simplified version of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons as well as the digital watersheds. Hydrocoding was applied to the routes. The reaches were not created but would be generated using the simplified version of the Base Stream and Flow Representation Lines as a base and the hydrologically corrected filled Alberta Provincial Digital Elevation Model plus the Base Hydrography Point Events to determine the breaks. The Base Watersheds consists of four data packages: Base Watersheds - Hydrologically Corrected Filled Digital Elevation Model (DEM), Base Watersheds - Simplified Hydrography, Base Watersheds - Watersheds and Base Watersheds - Routes. The four data packages are composed of: Base Watersheds Hydrologically Corrected Filled Digital Elevation Mode (DEM) Hydrologically Corrected Fully Filled Terrain Hydrologically Corrected Fully Filled 25 Metre Raster Hydrologically Corrected Fully Filled 100 Metre Raster Hydrologically Corrected Partially Filled Terrain Hydrologically Corrected Partially Filled 25 Metre Raster Hydrologically Corrected Partially Filled 100 Metre Raster Simplified Hydrography Simplified Linear Network Lines Simplified Linear Network Points Simplified Hydropolygons Simplified Linear Network Cross Reference Simplified Hydropolygons Cross Reference Strahler Order Coding Watersheds Fully Filled Watersheds Partially Filled Watersheds Strahler Order Coding Routes Single Line Network Routes Simplified Linear Network Routes Hydrocoding These feature datasets, feature classes and tables were generated using the Base Features Derived Watersheds and Hydrocoding Specifications documents. There are six documents in this collection: Overview Strahler Order Coding Filled Hydrologically Corrected Terrain Watersheds Hydrocoding Reaches Full descriptions of the individual datasets are included in the metadata for the four data packages.
Language of Dataset: en
Purpose: The Base Watersheds datasets were generated from a common base and are used in a variety of applications either as individual layers or as combinations of layers that are aligned. These applications are described in the metadata for individual datasets. The Base Watersheds datasets were intended to represent information at a 1:20 000 scale and can be used at an operational scale of analysis with some limitations. Limitations are outlined in the metadata for each dataset.
Supplemental Information: The Base Features Derived Watershed Delineation and Hydrocoding Specifications documents have been used to generate the Base Watersheds datasets. Not all of the datasets listed in the specifications have been created. The data were originally processed in ArcInfo format by subbasin (based on the Drainage Basins of Alberta 2006) for all of the individual datasets. The original datasets have been converted into feature classes and merged. Edge cleanup and reconciliation to the provincial boundary have been performed where appropriate.

Logical Consistency Report: The Base Watersheds datasets are based on the Alberta Provincial DEM source points and a simplified version of the Base Stream and Flow Representation Lines and the Base Waterbody Polygons. It should be noted that the source data layers are not consistent and contain data from different sources. All source data was processed by subbasin and the 21 individual blocks of data have been clipped where appropriate and merged into a single provincial layer. Variation by subbasin will exist due to differences in the source data and differences in processing.
Completeness Report: The dataset is complete for the provincial extent.
