The OpenStreetMap project provides increasingly extensive map data for the entire world that you can download and use for ANY purpose you like.
Usage of the geodata is controlled by a license. The most important thing about the license is that '''you do not have to pay anybody anything to use the data'''. There are NO copyright, license, usage or other fees. You may use the data for personal, community, educational, commercial, government or any other use that you can think of. We, the OpenStreetMap community, ask only two things in return.
Firstly, that you '''attribute''' OpenStreetMap, i.e. you show clearly where you got the data from. A lot of contributors have spent and spend a lot of time and effort adding data from virtually every country in the world. We would also like people to know about our project and perhaps use or contribute data themselves.
Secondly, you '''"Share Alike"'''. If you publicly distribute something that you have made from our data, such as a map or another database, and you have added to or enhanced our data, then we want you to make those additions publicly available. We obviously prefer it if you added the data straight back to our database, but you do not have to, as long as the public can easily get a copy of what you have done. If you do not publicly distribute anything, then you do not have to share anything.
Our current license is called [http://creativecommons.org/licenses/by-sa/2.0/ "CC-BY-SA", the Creative Commons Attribution Share-Alike version 2.0]. Here is the [http://creativecommons.org/licenses/by-sa/2.0/|human readable summary] and here is [http://creativecommons.org/licenses/by-sa/2.0/legalcode the full text].
But if you would like to support the project ... [http://donate.openstreetmap.org/ Donate Button]
== If I have data derived from OSM data, do I HAVE to distribute it? ==
No, The licence does not force you to distribute or make any data available.
== Can I charge for distributing OSM data or data derived from OSM data? ==
Yes. You can charge any amount of money you want for any service or data you provide. However, since the data (or service) that is derived from OSM data must be licensed as above, other people may then redistribute this without payment.
== Can I get permission from OpenStreetMap Foundation to distribute OSM data under an alternative licence? ==
No.
Under CC-BY-SA, the copyright to OSM data is vested in the individual contributors. If you happen to use data provided solely by one or a few OSM contributors, you can ask them if they are willing to provide their data to you under a different license.
Under the proposed ODbL structure, the Foundation will be contractually bound to the bulk of OpenStreetMap individual contributors to license the data only under a specific license. Initially, this will be ODbL 1.0. The Foundation will have the right to change that license to meet future conditions but only if is "free and open" and only under a mechanism that involves getting the consent of then active contributors. As with CC-BY-SA, copyright to individual contributions remains with the contributor and their consent can be asked directly.
== How should I attribute you? ==
== More information about ODBL ==
We will be creating this section soon.
