What are the available keyboard shortcuts?⚓︎

With macOS, replace Ctrl by Cmd.

Globals⚓︎

  • Ctrl+E → switch to edit mode
  • Escape → close open panel or dialog

  • Ctrl+E → back to preview mode
  • Ctrl+S → save map
  • Ctrl+Z → undo all changes until last save
  • Ctrl+M → add a new marker
  • Ctrl+P → start a new polygon
  • Ctrl+L → start a new line
  • Ctrl+I → open importer panel
  • Ctrl+O → open importer panel and file browser
  • Ctrl++ → zoom in
  • Ctrl+- → zoom out
  • Shift+click on a feature → edit this feature
  • Ctrl+Shift+click on a feature → edit this feature layer

Which syntax is allowed in conditional rules?⚓︎

  • mycolumn=odd → will match features whose column mycolumn equal odd
  • mycolumn!=odd → will match features whose column mycolumn is missing or different from odd
  • mycolumn>12 → will match features whose column mycolumn is greater than 12 (as number)
  • mycolumn<12.34 → will match features whose column mycolumn is lower than 12.34 (as number)
  • mycolumn= → will match features whose column mycolumn has no or null value
  • mycolumn!= → will match features whose column mycolumn has any defined
  • mycolumn=true/false → will match features whose column mycolumn is explicitely true (or false)
  • mycolumn!=true/false → will match features whose column mycolumn is different from true (or false)

When the condition matches, the associated style will be applied to the corresponding feature. When multiple rules define the same property, the first matching rule wins.

For example, let's imagine those rules defined in that order: - population>10000 then apply color=red - population>1000 then apply color=orange - unemployment<10 then apply pictogram=default - unemployment>10 then apply pictogram=warning

Now: - for a feature with population=1300 and unemployment=8, the color will be orange and pictogram will be default - for a feature with population=1300 and unemployment=12, the color will be orange and pictogram will be warning - for a feature with population=20000 and unemployment=15, the color will be red and pictogram will be warning

How to use variables?⚓︎

In general, using a variable is as simple as {myvar}.

It's possible to define another variable as fallback of the first one like this: {myvar|fallbackvar}.

To fallback to a string, add it between double quotes: {myvar|"fallback"}.

It's possible to combine more variables: {myvar|othervar|"some string"}.

It's possible to use a variable inside an URL, for example: [[https://domain.org/?locale={locale}|Wikipedia]].

Or even as source for an image: {{{myvar}}} (note the triple {}).

Available variables for features:⚓︎

Those variables can be used in a feature description, or in popup content templates.

Any property of the feature will be available, plus:

  • {lat}/{lng} → the feature position (or centroid in case of line or polygon)
  • {alt} → the altitude of a marker, if defined in the data
  • {locale} → the locale in the form en or en_US when a variant is used
  • {lang} → the lang in the form en or en-us when a variant is used
  • {measure} → the length of a line or the area of a polygon
  • {gain}/{loss} → the elevation gain/loss of a line (only if it contains the altitude information)
  • {rank} → the rank of the feature in the layer
  • {layer} → the name of the feature's layer
  • {zoom} → the current map zoom

Available variables in URL for remote data:⚓︎

  • {bbox} → the current bbox of the map in the form southwest_lng,southwest_lat,northeast_lng,northeast_lat
  • {north}/{top} → the North latitude of the current map view
  • {south}/{bottom} → the South latitude of the current map view
  • {east}/{right} → the East longitude of the current map view
  • {west}/{left} → the West longitude of the current map view
  • {zoom} → the current map zoom
  • {lat} → the latitude of the current map center
  • {lng} → the longitude of the current map center

Which statuses can have a map?⚓︎

Access statuses⚓︎

  • Draft (private): Only you and your collaborators are able to see the map.
  • Everybody (public): Everybody can see your map, it is listed on search results and potentially the homepage. It is indexed by search engines like Google.
  • Anyone with link: The map will be accessible only to people knowing the link. The map is not indexed by search engines.
  • Editors and team only: Only you and your collaborators will be able to see the map.

  • Editors and team only: the owner, editors and members of the linked team will be able to edit the map.
  • Everyone: Everybody can edit the map without even being logged in.

Only for maps created without an account:

  • Only editable with secret edit link: Only people with a secret link will be able to edit the map.

These settings are also available for each layer.
