Hello, I'm sorry, but I'm still not sure if I understand your question properly.
If you have a map pane and you want to zoom in to a particular location you can use the setDisplayArea method: http://docs.geotools.org/stable/javadocs/org/geotools/swing/JMapPane.html#setDisplayArea(org.opengis.geometry.Envelope) For example, if you want to display an area w map units wide, centred on a given position, you could do this: double xPos = ... double yPos = ... double w2 = w / 2; ReferencedEnvelope env = new ReferencedEnvelope(xPos - w2, xPos + w2, yPos - w2, yPos + w2, crs); mapPane.setDisplayArea( env ); If you are asking about the specifics of your database query then hopefully someone else here can assist you.

Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ Geotools-gt2-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users
