I don’t make formal maps with legends very often, but it seems to me it would be more useful for the raster value, such as elevation, be used as the default legend label, instead of the color bit number as the legend label.

I could be missing something. I’m not a cartographer.

How to symbolize & label Lidar raster layer in legend? What is 0-255?

The raster image in your map isn't pure elevation data, but rather it is a shaded relief image that uses shades of gray to represent how the terrain appears under a pre-defined light condition (often with an azimuth of 315 degrees and an altitude of 45 degrees). There are 256 gray values 0 - 255 in the raster to represent the brightness values, and in my opinion this type of raster doesn't usually belong in the map's legend.

@JesseWickizer Thanks, makes sense. I'd wondered but couldn't put my finger on it.
