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.

How OpenStreetMap Records Geographical Features


Given enough time, storage, and processing power, Osmosis allows you to extract, adapt, and store OpenStreetMap data in more or less any way you can imagine. If you are working with OpenStreetMap data in country-sized quantities or larger, it should be one of the first tools you use to get the information you want from the raw data.

You should now know how to perform the following tasks with Osmosis:

  • Read data from a planet file or a pre-built extract.

  • Read data directly from the OpenStreetMap API or XAPI

  • Write processed data to a file or database

  • Cut out an area of data using a bounding box or a bounding polygon

  • Extract a subset of features from a dataset using tag filters

  • Keep your source of data up-to-date using replication

If you use large amounts of OpenStreetMap data in an application or to create a map, eventually you will encounter problems that can only realistically be solved using Osmosis. For this reason, it's worth getting to know how Osmosis works, what it's capable of, and...
