to the map:

// Initialize WMS layer from our local GeoServer

buildings = new OpenLayers.Layer.WMS( "Medford Buildings",

"/geoserver/wms",

'format':'image/png'},

{'reproject': true});

// Add WMS layer to our map

Review the querying part in the link of http://workshops.opengeo.org/stack-intro/openlayers.html,

and navigate to C:\Program Files\ApacheSoftwareFoundation\Tomcat7.0\webapps\spatialdbtips\Ope

nLayers\examples, view the source code of the getfeatureinfo.html, getfeatureinfo-control.html, and

12. PostGIS

“PostGIS adds support for geographic objects to the PostgreSQLobject-relational database. In

effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend

spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's

Spatial extension.”

(Reference: http://postgis.refractions.net/)

Get familiar with PostGIS. Open PostgreSQL tools pgAdmin, you will see spatial data that we are

using is as the following structures (Figure 3).
