Abstract: 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.

Abstract:
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.
Purpose:
Provides users with an update of hydrography SLNET base data layer to support business applications and
decision making related to water course features. The Single Line Network (SLNET) layer was designed to
provide users with a connected network of single line hydrography.

Description:
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.
