Hi, re: > Is it possible if you can put the range from blue to red. I guess a > suggestion would be blue for 0, green (low values), yellow (moderate > values) and red to (high) values? Sure. The command you will use is EU (Enhancement Utility). A very simple answer to your question is: - load the image as before The default enhancement associated with a frame (enhancements and graphic tables are associated with frames, not the image) will be a gray scale enhancement that maps display values of 0-255 from black (0) to white (255) evenly. - modify the enhancement in the frame using EU: EU MAKE 0 255 BLUE RED - you can use EU to make new enhancements by specifying colors/ color ranges mapped to display values - there are a lot of enhancements included in the McIDAS distribution To see all of the pre-made enhancements that are available to you, run: EU LIST - you can load a pre-made enhancements (on at a time). Here are some examples (examine the result after each line is run): EU REST BREF24 EU REST IRSHORT EU REST IMGRGB EU REST IMAGE EU REST <- the default when no enhancement is specified is EU REST IMAGE Check out the enhancement section of the online Workshop Tutorial or Learning Guide: Unidata HomePage http://www.unidata.ucar.edu Software http://www.unidata.ucar.edu/software McIDAS http://www.unidata.ucar.edu/software/mcidas/ Documentation and Training http://www.unidata.ucar.edu/software/mcidas/#documentation McIDAS Workshop Tutorial https://www.unidata.ucar.edu/software/mcidas/current/workshop/toc.html McIDAS Learning Guide https://www.unidata.ucar.edu/software/mcidas/current/mclearn/toc.html Cheers, Tom -- **************************************************************************** Unidata User Support UCAR Unidata Program (303) 497-8642 P.O.
