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.

Managing data


The core of each map service is data. We need to create workspaces to group together datasets, connecting databases and folders containing data, adding feature types, and configuring their options. GeoServer's REST interface exposes resources for each one of them.

Working with workspaces and namespaces

A workspace is a logical entity you can use to group data. A workspace is always linked to a namespace URI that defines a web reference for it. The REST interface defines two resources that you can use to access these elements. They are as follows:

  • /workspaces
  • /namespaces

The GET, POST, PUT, and DELETE operations are defined for both of these resources, which allows you to view, create, update, and delete workspaces and namespaces.

Managing workspaces

We will use REST operations with workspaces. In this section, as in the others contained in this chapter, we will use both cURL and Python to perform the same operation.

The examples are shown in a Linux shell, but cURL and Python syntaxes...
