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.

OSM Mapper


OSM Mapper (http://www.itoworld.com/product/osm/) is a web-based tool provided by a British transport intelligence firm, ITO, and provides similar facilities to those on the openstreetmap.org website, but allows you to sort and filter the data for a given area. At present, OSM Mapper only processes ways, not nodes or relations, but is still useful for finding sets of data with particular tags, and edited by particular mappers.

You need to register at the ITO website to use OSM Mapper, including supplying an e-mail address, and responding to a confirmation e-mail. You won't receive any further e-mail from ITO after registering. The data in OSM Mapper is usually updated once per day, so any edits you make won't show up here immediately.

Creating an area to analyze

To look at the data using OSM Mapper, you need to define one or more areas that interest you. The size of an area is limited to prevent overloading the system, although the limit of around 40 miles across is still quite...
