Mosaic to New Raster gives always RGB in ArcGIS 10

JanVotrubec

Hello,
I have two IMG rasters 8bit unsigned, 1 band, discrete. When I do "mosaic to new raster" I always get 3 band RGB, even when I select 1 band (no matter if it is TIFF, ESRI GRID, IMG). Is there any other setting so that I can mosaic 1 band rasters into 1 band raster as it worked in previous 9.3.1 version?
regards,
Jan

Hi Jan,

From your description it sounds like the tool has a problem. Could you contact Technical Support so we can work with you to get a reproducible case? For now, try using the Mosaic tool. Take one IMG as input and set the other as the target.

Regards,
Eric

Hi Eric,

I had to switch back to 9.3.1. because I had also other problems with v10 and unfortunately no time for discovering why it does not work or what is implemented in a different way. In future I plan to have v10 in vmware and test it further.

regards,
Jan

Hi Folks,
I've been trying to get ArcGIS 10 working using WinXP installed as a virtual machine (VMWare) on my Macbook. I can't get any geoprocessing to work at all and keep getting the nebulous 999998 error. I can copy a raster to a different format but i can't generate slope, hillshade, add XY to point, etc. Have you had a similar experience? Do you know of any solutions?
Thanks,
Jonathan

I have this exact problem when using mosaic to new raster. Any update to this problem?

thanks,

Dan,

Please contact Technical Support so we can get a reproducible case. Have you tried to suggestion by Eric to use the Mosaic tool?

I have the same problem and it's driving me crazy. Any new advice?

The recommended Mosaic tool does work and produces a single layer merged raster. If ESRI Support wants to recreate this problem, I experienced it trying to merge two TIFFS of impervious surfaces data exported from http://gisdata.usgs.gov/website/mrlc/viewer.htm. The extent was the State of Massachusetts and about a 30-mile buffer of the neighboring states, a large enough area to generate two separate TIFFS. The Mosaic to New Raster tool produced a 3-layer RGB even though I explicitly selected 1 layer.

This just happened to me as well. When I merge the grids I get 4 grids in result. image, imagec1, imagec2 and imagec3. None of them retain the grid nature but attempt to convert the data to bands. The image file acts as if it has 3 bands.

Has this been sorted out yet?

Thanks

Based on your problem description, it appears that you are experiencing the following bug in ArcGIS 10:

[ NIM066773 Mosaic to New Raster tool gives an incorrect output when the input raster is a single band raster with colormap, only when Colormap Mode selected is FIRST]

Workaround: Select output location to be a file geodatabase, or use a Mosaic colormap mode other than FIRST. ArcGIS 9.3.1 also gives correct output.

Had the exact same issue. I had two images with a colormap internally stored. Tried "Delete Colormap"; didnt delete it... So I thought hey maybe I should just delete and rebuild everything. So I tried "delete attribute table". Got a red x and an error 000114: Failed to delete attribute table. Read the error message details and it suggested deleting the xml.dbf file associated with it. Once, I delete the two .dbf files for my two images, the mosaic tool worked fine for me.
