OpenGeofiction:Carto layer
The term "carto" (short for cartographic) has become a kind of standard way of referring to the default style of the OpenStreetMap render. The so-called openstreetmap-carto (osm-carto) has its code base hosted on github and is freely downloadable and installable. The particular style of map render has become idiosyncratic to OpenStreetMap, an aspect of its image or "brand" online, but it is also constantly evolving.
OpenGeofiction uses the same osm-carto style for its main (default) map layer.
Is OpenGeofiction's carto layer out of date?
Yes and no... We have two instances of the carto layer available:
- OGF-Carto - 5.9.0, and was current as of October 2024
- OGF-Carto (old) - 5.3.0, and was current as of August 2021
Updating the render software is not a simple task. Therefore we have opted not to try to "keep up" with the osm-carto code base. We anticipate updating maybe once a year or so.
Can we customize OpenGeofiction's carto layer?
In theory yes. In practice, no. It's hard. Sorry. Eventually we may develop a separate, custom OpenGeofiction render layer, similar to the way the histor layer used to work. This is not currently in development, however.
What are the technical specifications of the OpenGeofiction carto layer?
The OpenGeofiction carto layer is called ogf-carto in the code base.
