1. zip file with ESRI shapefile (consists with .shp, .shx, .dbf, .prj and etc.).

The extractor publishes the ESRI shapefile or Geotiff file to geoserver as WMS service. In order for the extractor to work, you need to two things:

Setting up Geoserver Extractor

The following software are needed for the Geoserver Extractor. Also it needs the "identify" command from Magik. Since Image Extractor is usually installed as default, we assume that it's already installed.

1. Install GDAL libraries

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install gdal-bin
sudo apt-get install python-gdal
sudo apt-get install proj
sudo apt-get install libgdal-dev

2. Update the extractor configuration

1. Edit /home/medici/extractor/server.properties with the following info:

geoserver.server=http://lowermississippi.ncsa.illinois.edu/geoserver
geoserver.owsserver=http://lowermississippi.ncsa.illinois.edu/geoserver/wms
geoserver.username=admin
geoserver.password=[password]

3. Restart Extractor Service

sudo /etc/init.d/medici-extractor restart
