Situation: I will be traveling in the next months and therefore, I have created a bunch of geolocated POIs and other layers, such as campgrounds, attractions, hiking trails and so on. I want to use these layers as my own information source either within a GIS (ArcGIS, QGIS) or building a web app with Leaflet. I can use the layers as .shp, .kml, .csv, .json, or any other vector format.

Problem: I need to use the data offline, as I often won't have Internet access. The main problem is, that I need any kind of offline base map, when visualizing my data. For OSM data, only vector data of layers are provided that can be downloaded.

Do you know of any other sources?

    Maybe you can interface with Osmand in someway? You're not telling us in what format(s) that bunch of geolocated POIs and other layers are in... – user4293 Jun 2 at 9:29

  • Why does Open Street Map not provide a basemap, that can be downloaded as background, but only vector data? – offlineCANUSA Jun 2 at 17:51
  • maybe not helpful, but perhaps creating pwa in this instance is ideal, considering you are planning on not having www access. i'm not sure how feasible that is with maps currently, but sounds right. – albert Jun 3 at 12:36

    If you want to work in ArcGIS, check out this article: FAQ: Can basemaps be used without an internet connection?. – csk Jun 3 at 18:46

If you want to go for Leaflet and offline (Raster) Tiles, you can checkout https://gitlab.com/IvanSanchez/Leaflet.TileLayer.MBTiles

For non-commercial products you can get free map tiles from https://openmaptiles.org/ (sign-up required).

  • good to know how to include mbtiles in Leaflet, but where can I get raster tiles from? – the_chimp Jun 4 at 6:56
  • Ah sorry, I forgot to mention that. Checkout openmaptiles.org, great stuff. I updated the answer. – geoM Jun 5 at 13:57
