SRD Mapping Activities Stakeholder Mapping Forum June 5th and 7th, 2007 Greenwood Inn & Suites Edmonton & Calgary
SRD Activity Overview • Access Update • ATS • Geo-Administrative Areas • Land Use Framework Base Data Initiative • Digital Imagery • Hydrography • Vegetation Inventory

Geo-Administrative Areas • Over 100 GeoAdministrative Areas captured to Base Features standard • ATS v4.1 reconciliation • Linked with update activities • Increasing demand for access to SRD/GOA Geo-Administrative Areas • Increased availability through AltaLIS • Currently 29 areas available
LUF Base Data Initiative Objective: To provide updated, upgraded or new information related to major base mapping data components: • Aerial Photography / Imagery • Access • Hydrography / Wetlands • Watersheds / Hydrocoding • Vegetation Inventory
2007 Imagery Partnership • Central Alberta MD/County Partnership • Composed of 14 MD/Counties and SRD in Central Alberta • Lead Municipality is the County of Wetaskiwin • Comprises about 625 twps • Digital Image Sensor • CIR, Colour, Pan Chromatic, DSM • Orthos & Aerial Triangulated Stereo Imagery
Single Line River or Stream River Representation Primary Flow Lines Arbitrary Flow Connector Isolated Lake Medium Rapids Island in River River Representation Primary Flow Line Single Line River or Stream Major River LB River Representation Secondary Flow Line Island in Lake Polygon Closure Line Large Rapids Minor Dam (hydrography point event) Major River RB Single Line River or Stream Lake Representation Flow Line Arbitrary Flow Connector Hydrographic Flow Flow direction established with Single Line Network and DEM. It is reviewed to ensure proper flow.
Hydrography Networks • Two Hydro Networks created • Simplified Linear Network + Strahler Order • Simplified Linear Network Routes + Hydrocoding • Two Hydrocoding Schemas used • Alphanumeric code (names, distances and orientation) • Numeric code with % distances and implied orientation)
Sand River Beaver River Strahler Order Coded Simplified Linear Network (Beaver River Sub Basin)
Summary • Access Update of approx. 1300 twps/year • Transition to ATS v4.1. Availability of LSD level of detail • Additional Geo-Administrative Areas • Hydrography Update commenced. Current focus is to complete update by watershed • Hydrocoding data created • Opportunity to upgrade/replace existing provincial DEM
