Bing Maps API vs TileStache: What are the differences?
Developers describe Bing Maps API as "The Bing Maps APIs include map controls and services that you can use to incorporate Bing Maps in applications and websites". The Bing Maps platform provides multiple API options for your application including Web Control, a Windows Store apps control, a WPF control, REST Services, and Spatial Data Services. Use the information below as well as at MSDN to help determine which API bests suits your needs. On the other hand, TileStache is detailed as "A Python-based server application that can serve up map tiles based on rendered geographic data". TileStache is a Python-based server application that can serve up map tiles based on rendered geographic data. You might be familiar with TileCache, the venerable open source WMS server from MetaCarta. TileStache is similar, but we hope simpler and better-suited to the needs of designers and cartographers.
Bing Maps API and TileStache belong to "Mapping APIs" category of the tech stack.
