CartoType () is a renderer and routing library. Available now for Windows,.NET, iOS, MacOS, Android, Ubuntu, Raspbian and any other platform that supports C++. Both map rendering and routing are usually done on the device using off-line data.
CartoType is owned and developed by Graham Asher of CartoType Ltd.
It can import OSM data to its binary format as well as data from other sources including ESRI shapefiles and USGS digital elevation data. Evaluation SDKs and demonstration programs are available.
