This will produce a float raster instead of an integer raster.</SPAN><BR /><BR /><SPAN>Cheers</SPAN><BR /><SPAN>Malcolm</SPAN></BODY></HTML> Thu, 20 Mar 2014 05:58:03 GMT MalcolmNunn 2014-03-20T05:58:03Z Problem standardising re-classed raster https://community.esri.com/t5/arcgis-spatial-analyst-questions/problem-standardising-re-classed-raster/m-p/270975#M3863 <HTML><HEAD></HEAD><BODY><SPAN>Hello,</SPAN><BR /><BR /><SPAN>I am trying to standardise (0-1) several re-classed rasters (re-classed to 1-7).&nbsp; When i use the ('raster' - min) / (max - min) in raster calculator it gives an output with values which are either 1 or 0 and nothing in between.&nbsp; It looks to take all the elements in 1-6 and make them 0 and the values in 7 it makes 1.</SPAN><BR /><BR /><SPAN>Anyone have any ideas where i might have gone wrong??? Its incredibly frustrating, I'm fairly new to Arcmap.</SPAN><BR /><BR /><SPAN>Many thanks</SPAN></BODY></HTML> Tue, 18 Mar 2014 19:01:12 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/problem-standardising-re-classed-raster/m-p/270975#M3863 BryanMcKearney 2014-03-18T19:01:12Z Re: Problem standardising re-classed raster https://community.esri.com/t5/arcgis-spatial-analyst-questions/problem-standardising-re-classed-raster/m-p/270976#M3864 <HTML><HEAD></HEAD><BODY><SPAN>Hi Bryan</SPAN><BR /><BR /><SPAN>I think that your raster calculator expression is producing an integer result, so all your output values are being rounded to 0 or 1.</SPAN><BR /><BR /><SPAN>Try changing your raster calculator expression so that one of your numerical values is a float, eg 1.0 instead of 1.
