Chapter 4. Accessing Layers

One of the main aims of this book is to help you learn how to publish your data. GeoServer lets you create layers, items containing configuration for your data, and the way they are represented on a map. In this chapter we'll go over different vector and raster layer output types and explore ways to use them. We'll discover a hidden gem called the Reflector . For good measure, we'll toss in some other output extensions.

We will cover the following points in detail:

• Vector output types including GeoRSS and GEOJSON

• Raster output types such as JPEG and PNG

• OpenLayers single tile and tiled output

• Freemarker temples

• Using the Reflector

• Output extensions
