Hi: In fire incident mapping, the convention is to eliminate most colors on a digital map, especially the vegetation classes, leaving mostly place names and brown contour lines. In Arc 10, this was pretty easy with a Tiff because you'd just click on the color map in the TOC, click on the colors you wanted to eliminate (usually green for veg) then change to 'no color.'
I haven't figured out how to do that in Pro nor have I figured out how to identify the specific code associated with the corresponding color (the identify tool has disappeared and the Explore tool doesn't seem to do it for a raster).
Also, some of my maps are sid and only show RGB. Is there a way of doing the same in those? Or, after figuring out above, is it just easier to convert to tiff then change?
Thanks!
George
