Hello, My name is ABHINAV. I am developing a web application for getting directions. I wanted to know how can I extract a particular part of a map from OPENSTREETMAP and accordingly program it for various purposes like: Intelligent Routing Cost and Time based calculations of the best. The app which I want to develop is on similar tracks with GOOGLE MAPS. So guys please help me and tell how can I program it according to my needs. Thank You, Abhinav |

First things first, you're going to need to find out about what OSM data contains. This page from the beginners' guide is a simple introduction. Next, you're going to need to download some data. The XML data for the entire planet is huge, but there are links to some area-based extracts on this page. To start with, you might just want to extract a very small amount of data locally to you - perhaps using XAPI or Overpass. Routing is a big topic in its own right and there are lots of issues to consider, but many of them are introduced here. |
