Alberta Township System Feature Classes


Geo administrative areas
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
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
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

Hydrographic Flow

Flow direction established with Single Line Network and DEM.

It is reviewed to ensure proper flow.



Hydrography networks
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
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
