GeoServer Beginner's Guide

Overview of this book

GeoServer is an open source server-side software written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer allows you to display your spatial information to the world. Implementing the Web Map Service (WMS) standard, GeoServer can create maps in a variety of output formats. OpenLayers, a free mapping library, is integrated into GeoServer, making map generation quick and easy. GeoServer is built on Geotools, an open source Java GIS toolkit.GeoServer Beginner's Guide gives you a kick start 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, style points, lines, polygons, and labels to impress site visitors with real-time maps.Follow along through a step-by-step guide that installs GeoServer in minutes. Explore the web-based administrative interface to connect to backend data stores such as MySQL, PostGIS, MSSQL, and Oracle. Display your data on web-based interactive maps, style lines, points, polygons, and embed images to visualize this data for your web visitors. Walk away from this book with a working application ready for production.After reading the GeoServer Beginner's Guide, you will have beautiful, custom maps on your website built using your geospatial data.

Tile Caching


This area was greatly improved in Version 2.2 of GeoServer. From here you can control almost all parameters of the integrated GeoWebCache. It is a Java-based application that complements GeoServer. It caches WMS tiles to the filesystem. These images are then used by WMS clients instead of going to GeoServer for each tile request.

When creating a new layer, you may choose if it has to be cached or not. The Tile layers section lists all cached layers and lets you review and modify parameters. It also contains a link to a layer preview very similar to that listed in the data section. The main difference is that this preview uses cached tiles.

GeoWebCache is a companion for GeoServer, and if it is strictly integrated, there are a set of global parameters for configuring it too. Caching defaults is your entry point for them.

The Gridsets option lets you create new tiling schemas or modify the existing ones.

All the tiles you are going to create when caching need to be stored on a filesystem...
