It allows you to create an ROI (region of interest) by selecting a feature on
the map and applying a buffer to it. Take a look at the ROIManager/ROIRenderer.php
code and how it implements the buffering using PHPMapscript. You will
need a later version of PHPMapscript compiled with GEOS for this to work.<o:p></o:p></span></p>
