Interactive world map

Question

I'm looking for a javascript world map, much like Google Maps, that can be embedded into a webpage, and extended so I can plot my own points on it. The major catch is that the map needs to be completely usable without an internet connection (i.e., local intranet). It doesn't need to have the same level of detail as Google Maps, but should be able to have a little bit of zoom capabilities. Any ideas?

Edit: I'm not talking about a street map, more like an atlas map, preferably with terrain data. Sorry

Answer 1

You may want to investigate OpenLayers, which is an open source web-based mapping engine.

Answer 2

I don't know of any engines off the top of my head, but there are several sources of map data that are free to use:

If you can utilize imagery without street data, NASA's Blue Marble project is handy. However, as mentioned by others, the data can be very large.

For street maps you could download the whole planet database from OpenStreetMap, but it's about 160GB uncompressed!

For topography, you could try GLOBE.
