Hiking
Hi,
currently I am using Android + Oruxmaps + OpenAndroMaps (Elevate theme) for offline hiking. Is it possible to resemble something close to that with the mapbox-gl data from osmscout-server? Does the data contain contour lines, hiking paths, and so on? Is it possible to create a theme which highlights those data and for example render hiking routes based on SAC scale? I had a look at Mapbox Outdoors theme. Comes kind of close (although the SAC scale is missing). But that would be a start...
Thank you for your thoughts! Bernd
Such data are not imported at the moment, but there is nothing preventing to do so. I will have to look up how to do it in terms of data that needs to be retrieved and how to show it.
Thank you. I am looking forward to using this on the upcoming Librem 5! :-)

Maybe adding support for user-supplied DEM files might be helpful? Apart from being better (at least from a LIDAR source) than gps heights in track recording, these can be used to produce map overlays such as hill shadows and slope maps (possible in Oruxmaps). So it may be also possible to produce a contour line overlay...

Will be there in time :) . Not sure whether with the contours though...

I am ont sure it will be easy to support user-provided data. Let's see when I get to it.
This feature would be great for me too. I currently use Android and OsmAnd which has some features I like. It is really helpful for me to have the ability for custom overlays similar to what @semicarbazid mentions in Oruxmaps. With some GIS and command line scripting I can put basically any raster into OsmAnd, including satellite imagery, custom slope angles and scanned topos, and overlay them with the OSM vector data in the app. Some things like this that would be great for me for hiking and similar activities in OSM Scout Server (or maybe Pure Maps) are:
- configurable over/underlays (maybe this is more of a client feature)
- elevation-derived layers: contours, hillshades, slope-angle shading
- custom raster layers for things like scanned topos and satellite imagery
- custom vector layers, at least for display, though adding to navigation would be great too
For the elevation layers, I see two approaches. OsmAnd seems to have separate maps for each type (contours, hillshades, etc) which I expect is simpler implementation wise and also probably requires less processing but almost definitely more storage. The other option would be to have just one (probably raster) elevation data set and derive the various layers from it. @semicarbazid is this what Oruxmaps does? Deriving the layers on the fly sounds resource intensive to me.
Integration of all these different types layers would be great, but at the very least having the ability to overlay custom user-provided raster/vector maps would cover 99% of my usage, as I can just make any layer I want myself. I'd be happy to help out with some implementation too if you think any of this is doable @rinigus
