Georeferenced Survey Plans

The federal government has plans for all surveyed parcels online as images, but they aren’t georeferenced. Here is a short recipe and dataset for fixing that.

Note: this post is from 2008 and suffers from link rot. Some work is needed to get things functional again.
Start here:
http://www.yukongis.ca/data/survey_plans/.

Process:

  1. Download plan as regular tiff from Canada Centre for Cadastral Management (CCM) – http://www.lsd.nrcan.gc.ca/english/srisdocs_e.asp?RG=YT&PLN=93521 where RG=YT is Region = Yukon, and PLN=93521 is Plan# 93521. For bulk download see scripts:

    fetch-CLSplans 84574 85779 86458 etc...
  2. Load into ArcMap along with Surveyed_Parcels layer from Geomatics Yukon Corporate Spatial Warehouse (CSW), use Yukon Albers projection. Note: This same cadastre data also available from ftp://ftpyukoncccm.nrcan.gc.ca/.
  3. Use the Georeferencing toolbar, georeference the image (using Update Georeferencing rather than Rectify)
  4. Move result from noref to georef folder.
  5. Add to unmanaged raster catalog Survey_Plans in file geodatabase.

Feel free to extend the set of georeferenced images and share the results.
