I have a group of raster images from lidar data (so a DEM). When loaded in, they all have different symbology - so their color scheme and color ramp are all different. I would like to create a group with images that all have the same symbology, so that I can visually compare topography between the adjacent images. There are approximately 600 images within this group, so I don't want to change the color scheme for each image individually.
I've tried changing the symbology of one image, and using the "apply symbology to layer" function, but this does not work because it seems my layer or group of images is not considered a raster layer... I also tried first making this layer a raster layer with "make raster layer", but the layer or group that I have is not considered a valid type of input.
I'm using arcmap 10.0. Any advice or suggestions on how to do this would be most helpful.
