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

2006 Imagery Partnership

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

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)

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
