Hi Everyone,
wasn't sure where to place this post, so I hope the Free chat is OK.
I need a few very specific overlays to use in Locus Map 4 for Poland (entire country). I know where to get source data from, but I don't know how to convert the data into .mbtiles format (I'm not a programmer, tried the MOBAC, but can't figure out how to do it). What I need is:
1. Overlay with forrest branches and branch numbers
2. Overlay with public 4x4 routes (non-paved)
For the firs tone I already found a WMS source - now all it takes is to convert it to .mbtiles overlay to use it offline:
https://mapserver.bdl.lasy.gov.pl/ArcGIS/services/WMS_BDL/mapserver/WMSServer
The second one also can be obtained.
I understand this is qualified work to be done here, so I am willing to gratify the work. Please contact me here or in a private message.
Or perhaps someone already did it and published the files?
Thanks!
Hi,
as you mentioned the best solution should be the MOBAC. I'm not extra familiar with it but there is some example of MOBAC configuration for using WMS https://mobac.sourceforge.io/wiki/index.php/Custom_XML_Map_Sources#Custom_WMS_map_sources
Please be sure you do not brake terms of use of WMS service (because downloading)
I would also consider using OpenStreetMap data when it comes to unpaved routes. You can use the default LoMaps which show OSM highway=track https://wiki.openstreetmap.org/wiki/Tag:highway%3Dtrack, but there is no information on whether the track can be used for 4x4.
You can also filter and download a specific OSM highways dataset with https://overpass-turbo.eu (for smaller areas) -> use GPX or KML format to export and after that import data into Locus.
Or you can use QGIS to export OSM data to mbtiles.
It's also possible to create a custom map and a Mapsforge theme (alternative to offline LoMaps, but it's quite a complicated task).
So there are more options, it depends on your specific needs, the type of source data, the area you are interested in, etc...
Thanks, Petr
Thank you!
But I'm afraid anything past moving the proper files in proper folders exceeds my possibilities. I gave MOBAC a shot (I did some html/css coding back in the days, so I figured, how hard can that be, right? ;) ) - but the program interface is totally unfamiliar to me. I found a few tutorials online, but the results I get are totally different to wan shows on the tutorial - so it is definitely not my thing to make my own maps.
I'd rather commission it to someone who enjoys creating the maps, and I'll stick to using them ;)
To be honest, I don't really know Mobac either. Maybe someone from the community can advise.
Anyway, maybe there are other more "user friendly" options.
- preloading the WMS map in Locus Map. Locus caches the last 1000 map tiles. It is therefore possible to browse a smaller area when you are online, and the last viewed map will remain in the cache even when you are offline.
- to use QGIS to create a raster data from WMS (please see https://www.reddit.com/r/QGIS/comments/16auzqj/extracting_data_from_wms_source/ ) and after you can use QGIS to export raster to mbtiles (please see the article https://help.locusgis.com/support/solutions/articles/47001094929-how-to-import-geotiff-or-geopdf )
terenovo_art, if you need to highlight secondary paved or unpaved roads or paths, then you can try this theme for vector maps. It can be used as a layer on top of the map.

I often use it to find roads that are cleared of snow in winter, but where there are few cars. It's great to ride a bike on such roads. :-)
