I'm looking for advice/guidance on strategies for offline basemaps.
After some investigation I've been able to generate a tile package (using Pro and Create Map Tile Package geoprocessing tool) using the tiled basemap services designed for export (http://www.arcgis.com/home/group.html?owner=esri&title=Tiled%20Basemaps&start=11&q). However, there seems to be a practical limit to both package generation time and size. 9 Levels for the whole world street map using 8-bit PNG took 68 minutes and 2.4Gb. Currently waiting for 10 levels to finish, but I'm guessing it will be > 4Gb.
Does anyone have data on how big a tile package for the whole world would be at each of the levels? I don't think we need all 20, but 14 might be good enough.
So questions about alternative approaches:
- Is it possible to package or download the vector basemaps for offline use?
- Has anyone generated a vector tile package (.vtpk) using the OSM data?
Are there any other offline basemap strategies or approaches that I haven't listed?
