Overview of this book

Imagine being able to create accurate maps that look how you want them to, and use them on the Web or in print, for free. OpenStreetMap allows exactly that, with no restrictions on how or where you use your maps. OpenStreetMap is perfect for businesses that want to include maps on their website or in publications without paying high fees. With this book in hand you have the power to make, alter, and use this geographical data in a collaborative way from anywhere on the Earth.OpenStreetMap was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive, or unexpected ways. This book will allow you to take control of your own maps and use them smoothly. This book introduces the reader to the OpenStreetMap project and shows you how to participate in the project, and make use of the data it provides. No prior knowledge of the project is assumed, and technical details are kept to a minimum.In this book, you'll learn how easy it is to add your neighborhood to OpenStreetMap using inexpensive GPS equipment, or even no GPS at all. You'll find out how to communicate with other mappers working in the same area, and where to find more information about how to map the world around you.Once you have your area mapped, you'll learn how to turn this information into maps, whether for use in print or online, large or small, and with the details you want shown. The book describes several rendering methods, each suited to different types of map, and takes you through a tutorial on each one.

Interacting with the data

Along the top of the slippy map are the navigation tabs for interacting with the data, or getting more information. We'll cover what most of these do in more detail in later chapters, but following a quick summary:

  • The View tab will take you back to the map viewer, and doubles as a permalink for the current view. Clicking on this tab will reload the current view and make an entry in your browser's history. If you want to use your browser's back and forward buttons to switch between locations, you'll need to do this for each place you want to move between.

  • The Edit tab switches to Potlatch—the online editor for OpenStreetMap. We'll cover this in Chapter 5.

  • The History tab shows a list of recent edits in the area you're looking at. This and other tools that show what edits have taken place are discussed in Chapter 5.


    The Edit and History tabs will appear in gray if you're looking at too large an area for those tools to cope with.

  • The Export tab takes you to the map...
