MapComplete has a few data layers available in the theme which have special properties through builtin-hooks. Furthermore, there are some normal layers (which are built from normal Theme-config files) but are so general that they get a mention here.

 gps_location 
==============



<img src='https://mapcomplete.osm.be/crosshair:var(--catch-detail-color)' height="100px"> 

Meta layer showing the current location of the user. Add this to your theme and override the icon to change the appearance of the current location. The object will always have `id=gps` and will have _all_ the properties included in the [`Coordinates`-object](https://developer.mozilla.org/en-US/docs/Web/API/GeolocationCoordinates) returned by the browser.






  - This layer is shown at zoomlevel **0** and higher
  - **This layer is included automatically in every theme. This layer might contain no points**
  - This layer cannot be toggled in the filter view. If you import this layer in your theme, override `title` to make this toggleable.
  - Not visible in the layer selection by default. If you want to make this layer toggable, override `name`




 Basic tags for this layer 
---------------------------



Elements must have the all of following tags to be shown on this layer:



  - <a href='https://wiki.openstreetmap.org/wiki/Key:id' target='_blank'>id</a>=<a href='https://wiki.openstreetmap.org/wiki/Tag:id%3Dgps' target='_blank'>gps</a>




 Supported attributes 
----------------------

 gps_track 
===========





Meta layer showing the previous locations of the user as single line. Add this to your theme and override the icon to change the appearance of the current location.






  - This layer is shown at zoomlevel **0** and higher
  - **This layer is included automatically in every theme. This layer might contain no points**
  - This layer is not visible by default and must be enabled in the filter by the user. 
  - Not rendered on the map by default. If you want to rendering this on the map, override `mapRenderings`

 type_node 
===========





This is a priviliged meta_layer which exports _every_ point in OSM. This only works if zoomed below the point that the full tile is loaded (and not loaded via Overpass). Note that this point will also contain a property `parent_ways` which contains all the ways this node is part of as a list. This is mainly used for extremely specialized themes, which do advanced conflations. Expert use only.

  - Not rendered on the map by default. If you want to rendering this on the map, override `mapRenderings`
