topic Raster Data Sets Won't Line Up in Data Management Questions https://community.esri.com/t5/data-management-questions/raster-data-sets-won-t-line-up/m-p/707977#M40119 <HTML><HEAD></HEAD><BODY><SPAN>I have two raster data sets of irrigated areas. One is Washington State Department of Agriculture (WSDA), the other is the United States. I am looking to compare the agreement between the two data sets using a weighted sum. Right now, the data sets are not lining up well enough to accurately assess the agreement. The US data has an undefined spatial reference, so since I opened the WSDA data first, it appeared to line up. Once I zoomed in on Washington, though, I noticed matching patterns between the data that are slightly offset. I have already tried Define Projection and Snap Raster, and those didn't seem to help. Suggestions?</SPAN><BR /><BR /><SPAN>Thanks,</SPAN><BR /><SPAN>Paige</SPAN></BODY></HTML> Mon, 25 Jul 2011 16:54:40 GMT PaigePruisner 2011-07-25T16:54:40Z Raster Data Sets Won't Line Up https://community.esri.com/t5/data-management-questions/raster-data-sets-won-t-line-up/m-p/707977#M40119 <HTML><HEAD></HEAD><BODY><SPAN>I have two raster data sets of irrigated areas.
