In a few days I go with a few friends on a hiking holiday. We’ll be visiting the German alps. Mainly the area around zugspitze/grainau. However I don’t have internet access there, so using the online openstreetmaps is simply impossible.
As I don’t have internet taking a smartphone isn’t really useful - I rather just take some old fashioned cards & compass; those always work.
I do like the effort of openstreetmaps however, is it possible to download say a 20 x 20 km area around grainau at scale 1:25000 and print them to pdfs?
It is possible to create topographic maps merging elevation information from other sources with OSM data and producing it so that it prints to a desired scale. I created such a map for some areas I go back country skiing in.
But I don’t know of an on line source that does that and allows you to print to scale and setting up the scripts and getting everything debugged is more than a few day’s effort. At least it was for me.
In the meantime, consider using OsmAnd on your smartphone: It can save load the OSM data as a database rather than tiles so the storage is not too bad and there are contour/elevation data files available for it too.
