Each layer has 4 bands (Red, Green, Blue, and Near-Infrared). I have created a false color composite of each satellite image (Band 1- NIR, Band 2- Red, Band 3- Green). </SPAN><BR /><BR /><SPAN>In order to analyze the variability of colors across the landscape, I hope to transform my ArcGIS layers into ASCII files displaying each of the colors as a number. </SPAN><BR /><BR /><SPAN>I have tried using the Raster to ASCII tool and a single text file is produced. I do not understand where the numbers in this text file are coming from or what the number values represent. I think each Band should be a separate ASCII file (one ASCII file for Band 1, one for Band 2, one for Band 3), I am just unsure how to convert a single band from a multi-band raster image into an ASCII text file. </SPAN><BR /><BR /><SPAN>If it is not possible to convert each band individually into an ASCII file, is their a way to combine all three color values into a single unique index?</SPAN><BR /><BR /><SPAN>Thank you, </SPAN><BR /><SPAN>Catie</SPAN></BODY></HTML> Tue, 18 Jun 2013 17:12:12 GMT https://community.esri.com/t5/data-management-questions/multi-band-image-raster-to-ascii-file/m-p/574145#M32511 CatherineFinkenbiner 2013-06-18T17:12:12Z Re: Multi-Band Image Raster to ASCII file https://community.esri.com/t5/data-management-questions/multi-band-image-raster-to-ascii-file/m-p/574146#M32512 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote"> I have tried using the Raster to ASCII tool and a single text file is produced.</BLOCKQUOTE><BR /><BR /><SPAN>The tool used the first band of the multiband raster.</SPAN><BR /><BR /><SPAN>You can access other bands by navigating into the multi-band raster in the Add Data dialog to select one of the bands.
