Offline Use of satellite/aerial Maps; Understanding caching of tiles
Answered
Greetings!
In a few weeks i will be traveling to Sarek National Park in northern Sweden and would like to get my hands on some higher resolution satellite pictures of the area for planning my river crossings. Now, "downloading" an area of the Satellite Map is not possible, but you can cache tiles that you loaded while looking at the map.
I could not find an option like "cache all tiles along my track", so just to understand, is my only option to manually scroll though the whole track so that the tiles get loaded and therefore cached? I guess i would have to do this several times for different zoom levels? Is there maybe an easier solution?
Thanks a lot and greetings from Germany!
Hi
I'm sorry, you're right—it's not currently possible to download satellite imagery for full offline use. Locus stores viewed map tiles in an internal cache as you browse, but this cache is limited to a maximum of 50 MB. Once that limit is reached, the oldest tiles are automatically replaced by newer ones.
In theory, it is possible to manually create an offline map from raster images (such as GeoTIFFs), but this is a fairly complex process. You can browse the Lantmäteriet data catalog at https://www.lantmateriet.se/, download the orthophoto data, and convert it into an offline format like .mbtiles.
