About This Book
Whether you have used GeoServer before or are just starting out with it, this book will give you the skills and knowledge to unlock the value of your spatial information and deliver great looking maps.
This book will take you on a journey from installing GeoServer in a production environment through to securing and optimizing it so it's ready for use. Along the way, you will learn how to optimize your raster data for efficient delivery, exploit data stored in a spatial database, style data to create great looking maps, use GeoServer as a proxy, create scripts to perform spatial analysis, and monitor the health of your server.
Consequently, if you are looking to unlock the potential of GeoServer to deliver powerful desktop and mobile web mapping solutions that exploit spatial and location-based data, the tutorials inside this book will meet your needs for a detailed solution.
