The data I'm working with is in <br>> EPSG:2274. So I create a field that is decimal (width 20, precision 5) <br>> and in the field calculator I use $area/43560 - (there are 43560 square <br>> feet in an acre). My result is one decimal off - instead of 195.30 acres <br>> I have 19.53 Acres. I've done this enough to where I'm questioning every <br>> button push. If I divide by 4356 I get the correct number. I'm currently <br>> doing this in Windows 7 OSGEO install QGIS 2.2.<br>> <br>> Anyway - can someone tell me I'm crazy...or not crazy. Projections are <br>> set correctly...cat has remained off the keyboard etc.<br>> <br>> Randy<br>> <br>> -- <br>> -----------------<br>> Randal Hale, GISP<br>> North River Geographic Systems, Inc<br>> http://www.northrivergeographic.com<br>> 423.653.3611 rjhale@northrivergeographic.com<br>> twitter:rjhale<br>> http://about.me/rjhale<br>> <br>> _______________________________________________<br>> Qgis-user mailing list<br>> Qgis-user@lists.osgeo.org<br>> http://lists.osgeo.org/mailman/listinfo/qgis-user<br></div> </div></body>
