User Guide for TEM_WHR.AML
(Terrestrial Ecosystem Mapping _Wildlife Habitat Ratings)

Introduction

Two Arc Macro Language (AML) scripts are available to facilitate the generation of map products from Terrestrial Ecosystem Mapping (TEM) spatial data, TEM database, and associated ratings tables. Specific methodologies for TEM are discussed in Standards for Terrestrial Ecosystem Mapping in British Columbia (RIC [now RISC], 1998a), and methods for developing wildlife ratings are discussed in British Columbia Wildlife Habitat Rating Standards (RIC 1998b).

The first script, tem_whr (TEM Wildlife Habitat Ratings), assists in managing ratings tables and scheme files. The second script, tem_whr (TEM Wildlife Habitat Mapping), uses ratings tables and scheme files to assists in generating map products. This user guide describes the tem_whr script.

Installation and Set-up

  1. Start ARC
  2. First make a workspace within which to work. Use the createworkspace command from the ARC prompt. For example, type 'createworkspace myworkspace'.
  3. Then move into the workspace with the 'w' command. For example 'w myworkspace'.
  4. Now put two sets of data into the workspace: (1) TEM ecosystem data and (2) TEM spatial data.

    If you are working on a provincial government UNIX box, then the TEM ecosystem and spatial data can be found at $AW/wld/tem/r*/<project_name>. Within each <project_name>, the spatial data coverage is named tecp_*. For example, the ARC coverage for the kirbyville creek TEM is named $AW/wld/tem/r4/kirbyville/tecp_krb. Copy this to your workspace with the command 'copy $AW/wld/tem/r4/kirbyville/tecp_krb kirb'. This will copy the coverage to your workspace and name the coverage 'kirb'. The spatial data will be in an INFO file titled kirb.pat, and the ecosystem data will be in an INFO file titled kirb.tem.

    If you are not working on a provincial government UNIX box, the the TEM ecosystem and spatial and ecosystem data can be found at:
    http://www.env.gov.bc.ca/esd/distdata/ecosystems/wis/tem/warehouse/
    where the data is organized by region. For example, if you are interested in the data for Klawli, look under Region 7. Click on Klawli, then download the data (tecp_kla.zip) which is stored in e00 format. Using the 'import' command from the Arc prompt will import the data into ArcINFO format. The spatial data will be in an INFO file titled *.pat, and the ecosystem data will be in an INFO file titled *.tem.

  5. Now you are ready to run the tem_whr tool. Run the tem_whr tool by typing the command '&r tem_whr'. If you are not working in a provincial government UNIX environment, you may need to copy the tool into your workspace before attempting to run the tool.
