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.

Time for action – KML preview


Let's try another preview format, KML. This time GeoServer will not open up an application as you select the layer to preview. In fact, KML is a data format and you will need another piece of software to display it on a map.

  1. If you haven't already installed Google Earth, you can download it from http://www.google.com/earth/index.html.

  2. Accept the license agreement and save the installation file.

  3. On the Layer Preview page, scroll to the topp:states layer and click the KML link.

  4. You are prompted for saving or opening the KMZ output file. Save it on your filesystem.

  5. Open the kmz file in Google Earth.

What just happened?

Ok, that was pretty cool. We had GeoServer displaying layers in Google Earth. Drop the book and play around with Google Earth. Zoom in and out, and notice how it streams data from GeoServer. Using the drop-down box, you can also preview layers in several other formats. SVG is ideal for importing into Adobe illustrator, for example.
