I have a raster that was created using Observer Points. So there is 16 fields in the Raster table. I was extracting for each field equal to 1. So that I have a raster of the cells that is seen by that one observation point. While doing this, I checked my TOC and noticed the seventh one that I extracted had been automatically classified with unique values based on the field values and was not a stretch classification like the rest. (Btw, my Observer Points shapefile is classified with unique values based on another field)... and the 16th one.. But the rest were all stretched.</SPAN></BODY></HTML> Tue, 01 Dec 2009 16:18:24 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/automatic-classification-bug/m-p/123617#M1703 ChrisCorwin 2009-12-01T16:18:24Z Default rendering behavior rules https://community.esri.com/t5/arcgis-spatial-analyst-questions/automatic-classification-bug/m-p/123618#M1704 <HTML><HEAD></HEAD><BODY><SPAN>When a single-band raster dataset is drawn, the rules for determining the default renderer are as follows:</SPAN><BR /><BR /><UL><BR /><LI>If your dataset has a color map, it will be displayed with the Colormap renderer using the colors stored in the color map. </LI><BR /><BR /><LI>If your dataset contains 1-bit data and the dataset does not have pyramids, the Unique Values renderer will be used with 0 set to white and 1 set to black.
