Hi Heather,
I just used the same AML myself -- I don't know how to do it in ArcMap
(which I hardly ever use), but I exported it the grid (with the three
r,g,b columns) to an image using:
(in ArcInfo workstation grid)
grid_r = outgrid.r
grid_g = outgrid.g
grid_b = outgrid.b
makestack grid2 list grid_r grid_g grid_b
(quit, and go to plain arc)
gridimage grid2 # outimage bmp
Then you will get an image, which is properly registered (with a world
file), that you can open in ArcMap or other GIS software. Or do what I do,
re-touch it in Photoshop and then upload to an SDE... Note that ArcGIS
offers to build pyramids for the image, so that you can get faster
display.

| Dear listers,
| Perhaps you've come across this problem before: if so, I'd
| appreciate your
| help. I've tried this question already on ESRI-L, with nary a reply.
| Hopefully, I'm being clear.
| I have ArcGIS 8.3, and a grid and spatial analyst license. I
| have no image
| processing software. For a series of maps, I want to drape soils on a
| hillshade in ArcMap. However, without 3D analyst, I had to
| download an aml
| to perform this drape
| (http://www.or.blm.gov/gis/mapping/techniques/presentations/pa
| inted_relief/n
| ewrelief.asp). The usage is:
| &run newrelief.aml <outgrid> <ingrid> <incolor.lut> <hillshade-grid>
| The input grid is the categorical (soils) data. The
| incolor.lut is a lookup
| table, with values that correspond to the soils, and 3 columns that
| represent red, green, and blue.
| The output displays beautifully in ArcPlot using this command
| reference:
| gridpaint %outgrid% value identity nowrap %outgrid%.lut
| How on earth to I get that lovely display in ArcMap?
| Basically, there are 3
| columns that correspond to RGB in the outgrid.lut, but how do
| I get ArcMap
| to read those colors?
| Thanks for your help!
