Why I did not integrate those functions in the Addons yet? Lack of time, not much work involving PostGIS since a while, not sure the code is working properly.<o:p></o:p></span></p>

<p class="MsoNormal">Thanks, Pierre. Did all that work stagnate? Have there been efforts to incorporate into the main PostGIS code? Just curious to know what happened. It would be a shame not to provide such useful functionality if there has already been substantial
work done.<o:p></o:p></p>

<p class="MsoNormal">My alternative at the moment is GRASS, which I've not found to be terribly flexible for incorporating into a larger workflow.<o:p></o:p></p>
