URL-parameters and URL-hash

This document gives an overview of which URL-parameters can be used to influence MapComplete.

What is a URL parameter?

URL-parameters are extra parts of the URL used to set the state.

For example, if the url is https://mapcomplete.osm.be/cyclofix?lat=51.0&lon=4.3&z=5&test=true#node/1234, the URL-parameters are stated in the part between the ? and the #. There are multiple, all seperated by &, namely:

• The url-parameter lat is 51.0 in this instance
• The url-parameter lon is 4.3 in this instance
• The url-parameter z is 5 in this instance
• The url-parameter test is true in this instance

Finally, the URL-hash is the part after the #. It is node/1234 in this case.

layout

The layout to load into MapComplete

userlayout

If not 'false', a custom (non-official) theme is loaded. This custom layout can be done in multiple ways:

• The hash of the URL contains a base64-encoded .json-file containing the theme definition
• The hash of the URL contains a lz-compressed .json-file, as generated by the custom theme generator
• The parameter itself is an URL, in which case that URL will be downloaded. It should point to a .json of a theme The default value is false
