Layer: Base Water Feature (ID: 0)

Sub Layers:

Name: Base Water Feature

Display Field:

Type: Group Layer

Geometry Type: null

Description: This group contains groups of layers of symbolic representations for label, single line and polygon areas of the Alberta Environment and Parks base hydrography single line network (SLNET) and polygon datasets. The SLNET layer designed to provide users with a connected network of single line hydrography, 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. The Base Waterbody Polygon is the Alberta Environment and Parks base hydrography polygon dataset designed to provide users with a full provincial extent GIS ready hydrography polygon base data layer to support business applications and decision making, related to water bodies and major water courses in Alberta. The dataset is comprised of a seamless provincial extent of hydrography polygon features collected from various sources of provincial base and resource map based data and some federal topographic data. This group is not visible beyond the scale of 1:27,733,946, with groups of individual layers, as well as individual layers displays governed by their own visual optimized scale thresholds. For detailed information concerning of the layers, whether within a group or individual, please refer to their individual layer descriptions. There are two (2) individual layers and three (3) groups consisting of groups of individual layers or individual layers. The two (2) individual layers are: 1) Sandbar / Wetland / Lagoon 2) Intermittent Stream / Aqueduct / Spillway The three (3) groups are: 1) Lake/River (not visible beyond 1:27,733,946) 2) Intermittent Lake (not visible beyond 1:3,466,742) 3) Stream (not visible beyond 1:27,733,946) The Lake/River group contains the following two (2) groups of individual layers: 1) Lake/River Label (not visible beyond 1:3,466,742) 2) Lake/River (not visible beyond 1:27,733,946) The Lake/River Label group consists of the following layers: - Lake/River Annotation (5M) - Lake/River Annotation (2M) - Lake/River Annotation Dam/Ferry (1M) Lower Display - Lake/River Annotation Lake (1M) Lower Display - Lake/River Annotation Major River (1M) Lower Display - Lake/River Annotation Fall/Rapid/Icefield (1M) Lower Display - Lake/River Annotation Island/Coulee (1M) Lower Display - Lake/River Annotation Dam/Ferry (1M) Upper Display - Lake/River Annotation Lake (1M) Upper Display - Lake/River Annotation Major River (1M) Upper Display - Lake/River Annotation Fall/Rapid/Icefield (1M) Upper Display - Lake/River Annotation Island/Coulee (1M) Upper Display - Lake/River Annotation Icefield (250K) Lower Display - Lake/River Annotation Hydro Point (250K) Lower Display - Lake/River Annotation Double Line River (250K) Lower Display - Lake/River Annotation Intermittent Lake (250K) Lower Display - Lake/River Annotation Perennial Lake (250K) Lower Display - Lake/River Annotation Dam/Ferry (250K) Lower Display - Lake/River Annotation Icefield (250K) Upper Display - Lake/River Annotation Hydro Point (250K) Upper Display - Lake/River Annotation Double Line River (250K) Upper Display - Lake/River Annotation Intermittent Lake (250K) Upper Display - Lake/River Annotation Perennial Lake (250K) Upper Display - Lake/River Annotation Dam/Ferry (250K) Upper Display - Lake/River Annotation Glacier/Icefield (50K) - Lake/River Annotation Canal/Ferry/Ford (50K) - Lake/River Annotation Fall/Rapid (50K) - Lake/River Annotation Intermittent Lake (50K) - Lake/River Annotation Perennial Lake (50K) - Lake/River Annotation Perennial River (50K) - Lake/River Annotation Reservoir (50K) - Lake Label (20K) - River Label (20K) The Lake/River group consists of the following layers: - Lake/River (5M) - Lake/River (2M) - Lake/River (1M) - Lake/River (20K) The Intermittent Lake group contains the following three (3) individual layers: - Intermittent Lake (2M) - Intermittent Lake (1M) - Intermittent Lake (20K) The Stream group contains the following two (2) groups of individual layers: 1) Stream Label (not visible beyond 1:866,685) 2) Stream (not visible beyond 1:27,733,946) The Stream Label group consists of the following layers: - Stream Annotation Heavy River (1M) Lower Display - Stream Annotation Light River (1M) Lower Display - Stream Annotation Moderate River (1M) Lower Display - Stream Annotation Heavy River (1M) Upper Display - Stream Annotation Light River (1M) Upper Display - Stream Annotation Moderate River (1M) Upper Display - Stream Annotation Single Line Hydro (250K) Lower Display - Stream Annotation Intermittent Hydro (250K) Upper Display - Stream Annotation Single Line Hydro (250K) Upper Display - Stream Annotation Intermittent Creek (50K) - Stream Annotation Perennial Stream (50K) - Stream Label (20K) The Stream group consists of the following layers: - Stream (5M) - Stream (2M) - Stream (1M) - Stream (20K) Data Use Limitations Use of the information is governed by the terms of the Open Government Licence - Alberta, in force as of the date you accessed the information.
