In addition, single line representations of polygonal features and single line arbitrary network connectors are in the file. The Single Line Network (SLNET) layer was designed to provide users with a connected network of single line hydrography. en 1981 1996 ground condition Complete As needed -121.000000 -109.000000 61.000000 48.000000 -121.000000 -109.000000 48.000000 61.000000 ISO 19115 Topic Category inlandWaters none stream perennial stream intermittent stream recurring stream indefinite stream representation line lake representation line river representation line canal representation line To access the data you must agree to the terms of the Open Government Licence - Alberta Your use of the information will be governed by the terms of the Open Government Licence - Alberta, in force as of the date you accessed the information.

Alberta Environment and Parks, Government of Alberta Government of Alberta Data and Information Security Classification Public ESRI ArcCatalog 9.3.1.3500 Feature Class Base Stream arcs are classified according to valid hydrography feature types, and each feature type contains attributes with valid value domains for feature type and feature code. Base Representation arcs are classified according to the type of polygonal hydrography feature type they are associated with. Arbitrary Flow representation arcs are classified according to whether they have been created using DEM or generated manually. Feature typing and attribution is complete for all single line hydrography arcs in Alberta.
