I have GPS data, how can I use it to help OpenStreetMap?
You can upload your GPS tracklogs to OpenStreetMap, so that you and others can trace over them to draw maps. You’ll need to be a registered OSM user before you do this. See tracks that others have uploaded. Once you’ve done that, you can use the GPS as a guide to drawing roads and paths for OpenStreetMap. You can do this by: • edit your data online, using Potlatch, an easy-to-use Flash program that runs within your browser; or • edit at home using JOSM, which provides a powerful way to edit GPS data locally on your computer into sensible tracks before uploading them to the server (there are other editors, too); • and if you don’t have a GPS you can still help, see Getting Involved.
