Michael, I searched around on the DirectPosition... Should I use the following to define it: Di DirectPosition dp = new DirectPosition2D(crs, lon, lat);
Also I'm confused on getting the area: double displayAreaWidth = ... Is this from the ReferencedEnvelope that can be extracted from the JMapPane.getDisplayArea? ReferencedEnvelope re = wrappedPane.getDisplayArea(); double displayAreaWidth = re.getWidth(); wrappedPane is my locally declared JMapPane.
