7.5 cm Aerial Imagery for Regina SK

Posted by gecho111 on 17 April 2019 in English.

The City of Regina added 7.5 cm ortho air photos of the city from early May 2018 to their open data website. I contacted them about enabling WMS so I could use the imagery in JOSM and they were happy to oblige.

Lots of detail!

Their server is slow serving up imagery so you may want to turn it on and off while panning to a new location. I checked the alignment with the surveyed road centerline dataset and it is dead center for the most part. Some areas such as around the university are a bit off, so don’t go moving all the roads to match the imagery.

The Bing imagery for the area is newer, but this imagery is much more detailed with flat lighting and no shadows.

Adding Image Server to JOSM

https://opengis.regina.ca/arcgis/rest/services/CGISViewer/Airphoto_Regina_2018_7_5cm/ImageServer

The get capabilites URL needed for setting up the imagery in JOSM is the WMS link in the upper left.

  • Go into the imagery preferences in JOSM and click the +WMS icon
  • Paste the GetCapabilities url in the top box
  • Click Get Layers (for me the window was too small and hid the layer selection box, I needed to drag the edge of the window to enlarge it)
  • Select the Airphoto layer
  • Select the Is layer properly georeferenced? (it is … mostly)
  • Enter a friendly name for the imagery
  • Press OK

You could suggest adding it to the osm imagery Index on GitHub, so that everyone using iD or JOSM in the area could use it.

Does Saskatoon have something like this?

I haven’t found anything, they have an open data portal but there isn’t a lot there http://opendata-saskatoon.cloudapp.net/
