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.

Rendering maps on Windows using Kosmos


Kosmos is a .NET application that renders maps from OpenStreetMap data based on sets of rendering rules normally stored in the OpenStreetMap wiki. Kosmos was written by Igor Brejc, and is available in graphical and command line versions. It can render single images or small sets of tiles, and can even provide a small web server for those tiles.

Kosmos is designed for rendering a small number of features. It reads OpenStreetMap data directly from XML files, and doesn't have an internal database. If you want to generate a map of an area larger than a small town, Kosmos probably isn't the tool to use. Kosmos can produce less complex maps of larger areas, but this is best accomplished using data that only contains the features you want to show. We'll show you how to do this using the extended API (XAPI) later in the book.

Kosmos doesn't include any data editing facilities, so if you want to change any data from OpenStreetMap before rendering it, you...
