The goal is to reclassify while maintaining as much of a gradient/pseudo gradient as possible, </SPAN><SPAN style="font-style:italic;">and </SPAN><SPAN> to be able to compare composite habitat suitability models with disparate data. That is, I could compare models that had 0-100 scales defined by equal intervals, but not by Jenk's optimization - since the classes are based on variability within each dataset. It seems that unless I group outliers with much lower values, when I isolate "top" ranking habitat, I end up with virtually no suitable area. I've been around the block on this one, and feel like I am bashing my head against a wall. I would love to hear any clever, statistically sound, or simple-yet-overlooked approaches that I might try.</SPAN><BR /><BR /><SPAN>Thanks,</SPAN><BR /><SPAN>HG</SPAN></BODY></HTML> Tue, 07 Aug 2012 20:37:12 GMT https://community.esri.com/t5/data-management-questions/what-is-the-default-reclassify-scheme/m-p/383270#M21955 HenryGlick 2012-08-07T20:37:12Z Re: What is the default Reclassify scheme? https://community.esri.com/t5/data-management-questions/what-is-the-default-reclassify-scheme/m-p/383271#M21956 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Does anyone know what the default reclassification scheme is for the Reclassify tool, when you have a raster symbolized using a gradient?
