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.

To use the exporter, click on the Export tab at the top of the slippy map. A sidebar will appear to the left of the slippy map showing the exporter controls:

The default area to export is the whole of the map view. You can change this area by changing the map view itself, which should be reflected in the coordinates shown at the top of the sidebar. Alternatively, you can click Manually select a different area and drag a rectangle over the area you'd like a map of. Finally, you can enter the coordinates of the area you want to map directly into the form, and a rectangle will be drawn on the map to show the area you've specified.

If you need to save the location of an area you're exporting, you can use the Permalink in...
