We have around 400 watersheds to monitor. Using UMN Mapserver and <BR>> PostGIS, public can easily observ forest cover change from time to time on <BR>> watershed base and also be able to check the impact of watershed <BR>> rehabilitation program on hydrologic parameter from time to time.<BR>> <BR>> > 2) What you find useful about it over anything else?<BR>> <BR>> I found much simpler spatial query campared to desktop GIS, especially<BR>> buffering operation. Using PostGIS I just need to run one SQL, but using <BR>> desktop GIS i need to go over many intermediate maps.<BR>> <BR>> > 3) Why you think there should be any book written focused on its use and<BR>> > of<BR>> > course if such a thing were to exist, would you buy it?<BR>> <BR>> For beginner or intermediate users any documents or books would be helpful,<BR>> especially spatial SQL.
