We are planning to develop a intranet web application which will display our location in each area (only UK).
Requirement is simple, a base UK map with street level zoom in and icons will be placed on top of the map.
Maps are required only for rendering.
What I would like to know is,
1 .How can I download only UK map data from OpenStreetMap?
2. How to render the map - the back end is going to be in J2EE and front end in GWT. Is there any Java API available to interact with the maps?
I have spent considerable amount of time in checking wiki and forums but could not get answers for the above questions. If these queries has been already answered please point me to the same.
You can get a Planet extract. See http://wiki.openstreetmap.org/wiki/Planet.osm#Downloading
The best option is probably Geofabrik, they provide extracts for most countries / parts of Europe. Though they don’t actually have an extract for the UK, but they do have them for “Great Britain” and “Ireland”, so you could combine these to get all of the UK.
