Citing à portée

When you publish results from à portée, in a paper, a report, an article or an application, name the site, the data version and the date you used it, and keep the credits of the sources the data is built from.

Citing the data

Give the data version, because results change from one version to the next. The current version’s date is on the About page.

à portée (2026). Walking times to everyday amenities in Canada, data version 8 October 2026. Ammil Industries Ltd. https://aportee.ca (accessed 13 October 2026).

In BibTeX:

@misc{aportee2026,
  author       = {{à portée}},
  title        = {Walking times to everyday amenities in Canada},
  year         = {2026},
  publisher    = {Ammil Industries Ltd.},
  howpublished = {\url{https://aportee.ca}},
  note         = {Data version 8 October 2026. Accessed 13 October 2026}
}

Replace the data version and the access date with your own. The sources and settings for the version you used are under Release details, and its limits are under Known limits.

Citing the site or a map view

Cite the map or a city page by its URL. When you share a map link, it keeps the view, the amenities and the travel modes, so it opens the same view later:

à portée. Walking access in Hamilton (map). https://aportee.ca/hamilton (accessed 13 October 2026).

To get this reference for the view on screen, choose Copy citation or Copy BibTeX under Cite in the map’s Share panel. The reference carries the view’s link, its data version and the day you copied it. It names the area the map shows; tick “Include the pinned place” to cite the pinned place itself.

Credits to keep with results

Credit the sources with any result you show: data from OpenStreetMap contributors, the Overture Maps Foundation and Statistics Canada, available under the Open Database License. For transit and bike + transit times, also add the transit operators’ credits, listed in the source notices for your data version. Every source and its licence is on Sources and licences.

Can-ALE and the Spatial Access Measures have their own authors: cite them, not à portée, for those values.

Using à portée in a product you sell, in paid client work or in public-sector work needs an agreement; see the terms of use.
