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.

We are going to 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 are identical in a Windows shell.

  1. The first step looks at which workspaces are defined in your GeoServer instance. This requires a GET operation. The following code shows you the syntax. cURL has a lot of options, you can have a look at all of them running it with the curl --help command from Linux and Windows. On Linux you can also have a look at the manual with the command man curl. The first option we use is –u. It stands for user authentication and you have to insert the user ID and password you set in Chapter 2, Getting Started with GeoServer, when we modified the default password.

    The -v option tells cURL to run verbosely, so it will output detailed information on the request processing. The -X option defines...
