Does anyone know where I can find some KML at different resolutions to show the grid reference for the Canadian topographic maps (CanTopo and toporama). Much like is displayed on the map here: http://wms.ess-ws.nrcan.gc.ca/wms/indexcouverture_cantopo

As you zoom in the grids get more detailed so I imagine I'd require multiple KML files to provide the different levels of detail.

Those look like the grids for the National Topographic System in Canada.

They can be downloaded from Geogratis as the Vector Indexes of the National Topographic System of Canada.

They are available as kmz or shp.

They can be converted to KML with ogr2ogr from gdal.

  • The link to the Vector Indexes of the National Topographic System of Canada has been changed to: ftp.geogratis.gc.ca/pub/nrcan_rncan/vector/index – Devin Cairns Oct 20 '17 at 21:06
