I am using the Multispectral Landsat imagery service from AGO. I want to do some Raster Calc math on Bands 4 and 5.
So far I can find no way to get Raster calc to see the values of the other bands. I can change the Processing Template over to Color Infrared and then see bands 4 and 5 on the screen. But the values are always 0-255 not the actual values - even when using stretch.
When I have the raw image separating out the bands using Catalog is no problem. But how can i do this with the service? I was to avoid any downloading.
Raw Image values
I can see some other pixel values in Identify.
What am i missing.
Thanks for any help.
