topic Calculating Standard Deviation of Cells in a Raster in ArcGIS Spatial Analyst Questions https://community.esri.com/t5/arcgis-spatial-analyst-questions/calculating-standard-deviation-of-cells-in-a/m-p/49451#M651 <HTML><HEAD></HEAD><BODY><SPAN>Hi everyone,</SPAN><BR /><BR /><SPAN>Cell statistics question for you.</SPAN><BR /><BR /><SPAN>I have 100 rasters of raw rainfall data in which the pixels each represent rainfall for that particular pixel on the landscape for a single year during the 100 year period. I have also created a raster that calculated the mean rainfall received in each pixel over those 100 years.</SPAN><BR /><BR /><SPAN>From these raw data rasters, I want to create a new set of 100 rasters (one for each year) that displays the standard deviation from the mean of each pixel (of the entire 100 years) for each pixel. </SPAN><BR /><BR /><SPAN>I have a feeling this will be likely solved with python coding, which I have a little bit of experience in, but I am unsure of what tool to use? It seems like Cell Statistics is on the right track, since it focuses on individual cells, but doesn't achieve what I am looking for. </SPAN><BR /><BR /><SPAN>Any other ideas on how to tackle this?</SPAN><BR /><BR /><SPAN>Thanks,</SPAN><BR /><BR /><SPAN>Colleen</SPAN></BODY></HTML> Tue, 19 Nov 2013 19:41:38 GMT ColleenStrawhacker 2013-11-19T19:41:38Z Calculating Standard Deviation of Cells in a Raster https://community.esri.com/t5/arcgis-spatial-analyst-questions/calculating-standard-deviation-of-cells-in-a/m-p/49451#M651 <HTML><HEAD></HEAD><BODY><SPAN>Hi everyone,</SPAN><BR /><BR /><SPAN>Cell statistics question for you.</SPAN><BR /><BR /><SPAN>I have 100 rasters of raw rainfall data in which the pixels each represent rainfall for that particular pixel on the landscape for a single year during the 100 year period.
