The cartographic rendering of geospatial data – MBTiles and UTFGrid

At this point, you may be wondering, what about the maps? So far, we have not included any geospatial data or visualization. We will be offloading some of the effort in managing and providing geospatial data and services to OpenStreetMap—our favorite public open source geospatial data repository!

Note

Why do we use OpenStreetMap?

• OSM already provides mirrored map services for quick reproduction in the basemaps

• OSM provides a very extensive and scalable schema for the kind of geographic features that you might find on a campus

• Various web, mobile, and desktop clients have already been written to interact with the OSM API

• OSM provides the databases and other infrastructure, so we don't have to

• OSM has a granular and reliable way to track changes, using the osm_version and osm_user fields, which complement the osm_id unique ID field

OpenStreetMap to SpatiaLite

To use the OSM data, we need to get it in a format that will be interoperable...
