Finding the right GIS basemap for your geospatial analysis is always a challenge. Large data providers are expensive and often limit their service to API instead of actual ShapeFiles. On the other hand, there are local data providers and OpenStreetMap but preparing such datasets and verifying their consistency and topology takes a lot of time and resources.
