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

In Pro, my Explore tool is definitely identifying the ColorMap.PixelValue ok. In the Explore drop down have you got it set to Visible Layers?

The solution to changing individual colours to NoData\Transparent appears to be in this post at the bottom: https://community.esri.com/t5/education-questions/how-do-i-change-color-on-colormap-using-arcpro/m-p...
