I finally found Color Model Conversion under the Image Analysis window in ArcMap (10.2.2). Highlight your image name at top of window ->Processing->fx->Right click on Identity Function -> Insert->choose Color Model Conversion from list. However it would not run on my 4 band Tiff. I don't know if this is because it is 4 bands (no option is given to select which bands to use for the color model) or because of its format. No useful error message, it just says the inputs are inappropriate.

Hello, I have a raster with a colormap. In the table of contents in Arcmap, the legend shows up with the values from the raster, 1, 2, 3, etc. But I want it to show the actual names of the classes, which are in an attribute field in the raster. Is there any way to get it to do this?

Here's one way: In ArcCatalog - Contents tab - click on the name of the raster and it will drill down to the individual bands. Drag each band from ArcCatalog into the Composite Bands tool.

This would be a really useful tool. I've often felt the same need, but I do it in other software.

1. Is there a way to change the default setting so a new polygon layer that is added comes in as a colored outline (no fill) rather than a solid color? 2. In the color ramps for coloring polygons by attribute (i.e Categories->Unique Values), all the choices are for solid colors, none for outlines. Is there any way to generate a bunch of different colored outlines by unique value? A couple things I've been wondering about for a long time that would save me lots of effort. Fiona

FYI Converting polygons to points is much faster if you export to shapefile format rather than the geodatabase. Surprising timings for a dataset with 183923 features, using the Feature to Point tool in ArcGIS 10.1 with the INSIDE option: File geodatabase polygon to point fc: ~25 minutes Polygon shapefile to point shapefile : 27 minutes Fgdb polygon fc to point shapefile: 1 minute.

Just to clarify, I did create the geodb in 10.0. But after that I imported data while working in 10.1. Other datasets within the geodb are OK, only the raster with the colormap seems to be a problem. Thanks, F.

I have a raster in a geodb. It's just a raster in ArcGIS's native format, not a mosaic dataset. I am working in ArcGIS 10.1, but the client has Arc 10.0. We found that the raster is not recognized in 10.0. The only way to make it viewable in 10.0 is to delete the colormap. But the colormap is actually quite important. Is there a way to have a colormap in 10.0? I could not find any info on this backward incompatability problem in the ArcDoc.

In Symbology, change rendering from Colormap to Unique Values. You should see the same colours but only 14. If there are extra entries for nonexistent values, delete them. Then Export Colormap. Go back to the Colormap tab. Import the same Colormap that you just exported. You should now have the same colormap without the extra values.

FYI: ET Geowizards has a tool to calculate thickness and circularity of polygons (Polygon Characteristics) and its Eliminate tool allows you to eliminate on this basis. This is one of the licensed features.
