Contributors' guide

This Contributors' guide will show you how to add data to OpenStreetMap.


You will need is a computer connected to the internet and about 90 minutes to complete the tutorial. Each stage in the tutorial should be completed in order, but it is not necessary to do this in one go.


This guide is organised into five stages as follows:

  • Sign up to OpenStreetMap Which will take you through the process of signing up and explains the reasoning behind the terms and conditions.
  • Familiarisation Which will show you how to choose a place to practice on let you try the editor (but not actually save any changes)
  • First edit Where you will add at least one point feature to OpenStreetMap, at least one line feature and possibly also realign a few existing features.
  • more...

At the end of this tutorial you will have added a small amount of unique new data to OpenStreetMap which will be available to millions of people around the world forever for free. Some people make over a few small adjustments or additions to the map, they may correct the name of single street name, or add one point of interest and then move on; others become prolific contributors and add thousands of features over a long period of time. Whatever your plans, thank you for making OpenStreetMap just that bit better!
