Complete Gravel Maps for Sweden ready made for everyone's enjoyment can be downloaded down below!!
I have processed all the road datasets from NVDB (National Road DataBase) and extracted road features categorised as having a surface of "grus", ie Gravel.
The Gravel Road data has then been combined with a Base Map to form a complete map in MBTILES format
Want the quick version?
1) Download Gravel Maps to your phone, the whole country or one of the six regions I have built
2) For Android download the app OruxMaps. iOS is not my real but GAIA GPS seems to work
3) Go Ride Gravel!
Now, this is really just the tip of the iceberg as far as Gravel Map Data is concerned.
I use these Gravel Maps as a backdrop on my phone with routes created in other applications. On my computer i use the GIS system QGIS where I have loaded all the road data, background maps, aerial imagery etc
I then use the trace functions in QGIS to easily create routes and then I just transfer them to my phone using synchronized folders in Dropbox
Raw Data can also been downloaded below
These Data Sets are compiled by Län (County) and I have exported the gravel roads in three different formats, SHP, KML and GPX. By overlaying this data on top of a Base Map it's easy to distinguish between paved roads and gravel roads. With the right Base Maps it's also easy to figure out if there are any trails that could link up Gravel Sections that would otherwise end up in dead ends. This is basically what I do in QGIS
On this page I will not go into detail as to how these formats are constructed or how you are supposed to use them. My reasoning is that if you have found this link and bothered to read all this you might actually know what GIS data is all about :)
You will also find base maps that work well with the Gravel Roads, as well as links to the software and applications that I use to scout and create routes with!
