GeoServer Beginner's Guide - Second Edition

By: Stefano Iacovella

Overview of this book

GeoServer is an opensource server written in Java that allows users to share, process, and edit geospatial data. This book will guide you through the new features and improvements of GeoServer and will help you get started with it. GeoServer Beginner's Guide gives you the impetus to build custom maps using your data without the need for costly commercial software licenses and restrictions. Even if you do not have prior GIS knowledge, you will be able to make interactive maps after reading this book. You will install GeoServer, access your data from a database, and apply style points, lines, polygons, and labels to impress site visitors with real-time maps. Then you follow a step-by-step guide that installs GeoServer in minutes. You will explore the web-based administrative interface to connect to backend data stores such as PostGIS, and Oracle. Going ahead, you can display your data on web-based interactive maps, use style lines, points, polygons, and embed images to visualize this data for your web visitors. You will walk away from this book with a working application ready for production. After reading GeoServer Beginner's Guide, you will be able to build beautiful custom maps on your website using your geospatial data.

Using an external GeoWebCache


The integrated GeoWebCache is a convenient way to use a powerful caching tool while avoiding the complexity of an external installation and configuration. So, what is the point of using an external instance of GeoWebCache?

In a production environment, you will often have to deal with multiple GeoServer instances, running in parallel like a cluster. Indeed, we will see how to configure such a scenario in Chapter 11, Tuning GeoServer in a Production Environment. When more than one GeoServer publishes the same data, you cannot efficiently use the integrated GeoWebCache. There is no way to connect all the GeoServers to a single GeoWebCache. Anyway, it would make no sense as you will introduce a single point of failure in your architecture.

So, you have two ways to go--using the integrated GeoWebCache on each GeoServer node, duplicating the tiles and wasting a lot of space, or installing an external GeoWebCache and linking it to each GeoServer node.
