Where can I get offline maps for an application being developed with api for geotracking and attractions?

Question

Mobile development

Hello,
the maps are of interest for the Canary Islands. The application with them must work offline. It should be possible to search for objects by coordinates (user entry into the object zone). You also need the ability to build a route and see the sights and cafes.
Can you advise?

Answer 1

Download maps here
deploy Geoserver
for yourself All maps are yours, refer to them to your health.
As for offline, I won’t tell you if android can read .shp
At the very least, you can figure out leafletjs
