----------------------------Original message---------------------------- Can anyone out there help me with my customers request? What is the datum, ellipsoid and projection parameters of topographic sheets for the south western Argentina bordering Chile. I expect its the same for the entire country's maps. We will probably have to purchase these maps from MapLink. Any information is greatly appreciated !! Brad Green ========= WORLD OF MAPS ========= 118 Holland Ave. Ottawa,ON, Canada. Tel.
