Extra output options

The GeoServer gives you the ability to extend the output options for your data using extensions. Most of those extensions require additional setup; outside of dropping a JAR into WEB-INF. Let's look at a few that you might consider.

GDAL and OGR output

This is based on the GDAL library, and used for WFS output raster graphics. Using the ogr2ogr command, you can convert to several output formats. With OGR, you can convert from one vector format to another. We'll get into examples in future chapters.

Note

Take a look at the following links for more information on GDAL:

• http://docs.geoserver.org/latest/en/user/data/gdal.html

• http://docs.geoserver.org/stable/en/user/extensions/ogr.html

• http://www.gdal.org/ogr/ogr_formats.html

TEXT/HTML

One of the ways you can get information from GeoServer about features you click on is by querying WMS with a point, and getting a list of surrounding features.

The outputFormat format can be anything. The INFO_FORMAT should be text/html.
