need a mapping service like google maps - but for my intranet

Question

i have built a solution around google maps api but realized that it doesn't work when i deploy it to my intranet. after reading it seems like you need the premier service for this. Is there any other similar maps api tools that you can use free on your intranet website?

EDIT: from what i have read it seems like Yahoo allows you to use your free maps on intranets. can anyone confirm that you are doing this.

Answer 1

I would investigate OpenStreetMap:

• Content is open (Creative Commons Attribution-ShareAlike 2.0)
• There is good open-source library support

The catch is the data isn't always as accurate or complete, but coverage in major cities is good and the project keeps getting better.

You might also look into Microsoft and Yahoo! mapping licenses.
