topic Calculating area of raster in Data Management Questions https://community.esri.com/t5/data-management-questions/calculating-area-of-raster/m-p/247430#M14083 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I have an xy point file that I have run an IDW on. Using Model Builder, I created a simple model to run the idw, save to a layer file, apply symbology (so that it is automatically classified using quantiles), reclassify, save that as a layer file, and apply symbology to that layer (again, to automatically reclassify). My plan was to then convert to polygon, and query out some of the data using an SQL in order to calculate area for the top 60 percentile. However, I am unable to use my layer file in 'Raster to Polygon' tool. </SPAN><BR /><BR /><SPAN>My question is, then, is there a method or tool that can be used to apply my layer file in order to convert to vector? Or, is there an easier way to calculate the area of a predetermined percentile of data (in either rater or vector format)?</SPAN><BR /><BR /><SPAN>Thanks in advance <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span></SPAN></BODY></HTML> Tue, 24 Jul 2012 13:44:43 GMT ChelseaSmith 2012-07-24T13:44:43Z Calculating area of raster https://community.esri.com/t5/data-management-questions/calculating-area-of-raster/m-p/247430#M14083 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I have an xy point file that I have run an IDW on.
