New release now available v20210216.
i have updated the first post with the latest release notes and links. I'm now using google drive to release the theme in a shared folder that contains all the releases and the PDF legends.
In this update I have added support for depicting road surfaces and distinguishing between sealed and unsealed roads/tracks. This is applicable to all highway types (including pedestrian and cycle paths) except for motorways.
The attached is a graphical summary (as presented in the map legend) of the new overlay options:
- "dash unsealed roads" to give unsealed roads a dashed outline/casing.
- "road surface/grade textures" to give unsealed roads a textured pattern that represents the type of surface, visible from Z14 onwards.
- "emphasise road surface/grade textures" to highlight roads surfaces at lower zoom levels, visible from Z12.
The second attachment identifies which "surface" and "tracktype" tag values are mapped to the new surfaces.
not all maps support the "surface" tag, but do support the "tracktype" tag. For this reason, the "tracktype" tag is also used to set the road surfaces, albiet at a lesser level of detail (normal, compacted, gravel, dirt). Note that tracks tagged as trackype=grade1, which are also tagged with surface=asphalt, are now "promoted" to sealed roads (solid casing).
I am conscious that I have highjacked a feature of standard OS maps on which they use dashed road casings to represent unfenced roads (in fact a road can be solid one side and dashed the other to show fenced/walled/constrained on just one wide). However, since OAM/LM maps do not (currently) support a tag for fenced roads it seemed a good idea to use the same symbology for sealed/unsealed roads...
These new options are not enabled by default, as the default overlay options are for classic/standard OS map look/feel, and of course OS maps do not have such features.
