A while back I had taken a look comparing my local OGL to others in our area that were approved and listed on the wiki. Noting the similarities to existing documents I added our local cities as well per their attribution requirements. This differs slightly from documentation the that the legal working group has produced here https://osmfoundation.org/wiki/OGL_Canada_and_local_variants

I’ve not heard back from the legal questions email with my question after a few days now. But wanted to keep productive and provide supporting due diligence I am able to help out on. This seemed like a reasonable platform to use for such.

Comparing the latest “reviewed and approved” OGL from Guelph https://explore.guelph.ca/pages/open-data-license

To Edmonton and Calgary which are in turn based on the Alberta licenses. https://data.edmonton.ca/stories/s/City-of-Edmonton-Open-Data-Terms-of-Use/msh8-if28/ https://data.calgary.ca/stories/s/Open-Calgary-Terms-of-Use/u45n-7awa/ https://open.alberta.ca/licence

The majority of the documents and verbiage are identical, the differences i am able to note are as follows:

  • Preambles differ slightly for each document; however all roll up to the OGL - Canada
  • General formatting
  • Call out to relevant local attribution, acts
  • Alberta, Calgary and Edmonton add an additional exemption for “Information or Record that are not accessible under applicable laws” with an extra definition for “Records” pointing to the Alberta freedom of information and protection of Privacy act. Guelf (and others) directly reference the act as “information not accessible under the municipal freedom of information and protection of privacy act”

City of Edmonton Open data primer

於 2022年十月10日 由 KevinOsEnglish發表。

City of Edmonton has an excellent data set to assist with entry into JOSM. navigate to https://data.edmonton.ca/ to locate data sets.

example: Street lighting https://data.edmonton.ca/Transportation/LED-Streetlights-Map-View/9xmi-y7kn

This is a giant data set, but data can be exported for use directly to CSV, XML, etc.. or you can further make use of the API to select a subset by clicking on the view source data:

rxke-mcvd : verify the right data set endpoint location radius (in m?)

https://data.edmonton.ca/resource/rxke-mcvd.geojson?$where=within_circle(geometry_point, 53.595, -113.479, 1000)

adjusting the circle to a suitable radius and location in the city to start working with the data, consult the API for more details on points vs geometry.

Once downloaded as geojson, import to JOSM to help with your edits.
