Beschreibung

OpenLayers is an open source JavaScript web mapping library distinguished from other alternatives, like Leaflet or Google Maps APIs, because of its huge set of components. Having being on the scene for a long time, users can benefit from a large set of resources and documentations, and a wide and actively supportive community.Instant OpenLayers Starter gives you the possibility to produce your first “real” web map without being an experienced programmer or a GIS specialist. It provides you with an overview of the most popular vector and raster data formats used to share spatial information on the Web. By the end of the book you will be able to amaze your boss with a brand new web map and a bag of skills to give life to your geodata.Instant OpenLayers Starter guides you through a fast and effective journey of web mapping, to discover how easy it is to put maps in your web projects, from simple base maps to interactive geo mash-ups, Google Maps, OpenStreetmap, GeoRSS, Panoramio, and your data. Starting with a lot of geo-information sources and a powerful library, we will explore how to manage maps inside web pages using basic third-party base maps to the overlay of re-projected vector data, going through styling thematic data and data interaction.

About the Authors

Alessio Di Lorenzo is a Marine Biologist and an MSc in Geographical Information Systems and Remote Sensing. Now he is living in Pescara, Italy, the place where he was born in October 1979.

One fine day, looking for suitable tools to represent and analyze the environmental phenomena, he discovered GIS and decided that it was worthwhile to investigate the topic. By mixing his personal interest in computer science, open source software, and programming languages with the spatial knowledge, he has concentrated more and more on Web Mapping and Web GIS.

Nowadays, he works as a consultant and trainer for local and central governments and various organizations. Most of his experience concerns the use of geospatial and web technologies to study and manage data from emergency and monitoring plans in the environmental, veterinary, and public health fields. He is author and co-author of articles concerning GIS for various scientific papers and for the TANTO blog.

When not having fun with maps and connected stuff, he likes to spend his time swimming and riding his mountain bike or his motorcycle!

Giovanni Allegri has a degree in Earth Science from the Centre for Geotechnologies (CGT) at the University of Siena (Italy). He works as a GIS freelance consultant and analyst for public agencies and private companies. His work fields range from spatial data modeling and GIS analysis, to GIS/WebGIS software development and cartography.

He holds courses on spatial DB design and management, GIS analysis, and WebGIS development, mainly based on free and open source technologies.

I want to thank my colleagues in the editorial staff of the Italian blog TANTO, for sustaining the authoring of the current work. I also want to say thanks to the OpenLayers community and the other GFOSS communities for the precious work in spreading and sharing an open knowledge for geography and geomatics.
