topic Using Reclassify Tool w/ Decimals in Geoprocessing Questions https://community.esri.com/t5/geoprocessing-questions/using-reclassify-tool-w-decimals/m-p/689402#M22856 <HTML><HEAD></HEAD><BODY><SPAN>I'm working with some data that will be used to create a complex model in Model Builder. I'm trying to take a Stronghold Watershed layer that has three classifications (high priority, medium priority and low priority) that has been converted into a raster and reclassify the values in the field the conversion was based on. The values are 2, 1, and 0 respectively. I want to reclassify the values to 1, .5, and 0 respectively. When in the reclassify tool it will not keep the .5, it keeps switching it back to a 0. The precision control seems to be to allow decimals but I can't get it work. Anyone have any suggestions?</SPAN></BODY></HTML> Thu, 31 Jan 2013 11:33:07 GMT KristinGriffen 2013-01-31T11:33:07Z Using Reclassify Tool w/ Decimals https://community.esri.com/t5/geoprocessing-questions/using-reclassify-tool-w-decimals/m-p/689402#M22856 <HTML><HEAD></HEAD><BODY><SPAN>I'm working with some data that will be used to create a complex model in Model Builder.
