The process I've used for creating raster datasets in 10.1 doesn't work in 10.2. Why?

ToddMacPherson — Tue, 24 Sep 2013 15:47:39 GMT

Hello

The process that I have always used to create large raster sets in 10.1 does not work in 10.2 and I do not know why.

The process was as follows:

- Create a file geodatabase
- Create a new empty raster dataset
- Set the Spatial Reference
- Set number of bands to 3

In 10.2 it creates the empty set correctly but when I try and add multiple .img files to it using 'Load Data' the progress bar flashes across the screen in the blink of an eye and is always 0%. It runs through each raster quickly saying 'Loading Raster1.img' etc. It completes in seconds with no errors. However when I try to display it, I get a blank screen.

Doing this process the exact same way with 10.1, it works flawlessly. It adds each img to the dataset and displays perfectly.

Any idea what is going on?

Thanks

This is weird. I just discovered that in 10.2, if I create a personal geodatabase and then follow the steps; then it works. It always worked as a file geodatabase in 10.1 but not 10.2.

Can anyone tell me why?

I am using ArcGIS Desktop and Win 7 64-bit in both cases.

Thanks

I have also found this at 10.2. I am currently working with ESRI Canada technical support on this however I can't seem to convince them that it is even an issue. I have given my tech support guy 2 identical geodatabases where I loaded rasters into a raster dataset, 1 was a 10.1 file geodatabase that worked fine and another was a 10.2 file geodatabase that contained only "No Data" for the cell values and displayed a white screen. He seems to think this is acceptable somehow.

Not impressed at all.

This also does not work with SDE at 10.2, it only seems to work in a personal geodatabase. The funny thing is that my SDE is still at 10.1, so it looks like it's something that desktop is doing at 10.2, not a problem with the actual geodatabases.

Tech support says no data in the cells is not a problem? 😕 To me this is now a known bug. Come on ESRI this is not acceptable. I have wasted a week on this before going back to 10.1.

Please keep us informed of your progress.

Well so far not a whole lot of progress other than I finally convinced ESRI canada technical support to open up a case with ESRI US technical support. My Canadian tech support guy clearly does not understand the issue as he is insisting that my issue has to do with statistics not being calculated on my source data which (a) I've never had to worry about in the past and (b) Just to humour him I did actually calculate stats on my source data and it made no difference, but he still says that's the problem.

The maddening part for me is that I have to go through ESRI canada technical support which is in the past has been beyond useless when it comes to actually solving problems for me. If I could just talk to someone in Redlands about this I'm sure I could get a whole lot further a whole lot faster, but instead I have to play this ridiculous telephone game where I tell the guy in Toronto my problem who then has to call the guy in Redlands and tell him the problem as he understands it.

I'm thinking of just downgrading to 10.1 if I don't get answers soon as I just have to get this work done and don't have the time to wait for someone to acknowledge that the workflows I have been using for the past 8 years are actually broken now.

Thanks for chasing this. A bug is a bug.

Can you please indicate more about your input data. I see you mentioned 3 band, but not bit depth or anything else about the input rasters? Usually 3 band rasters are either 8 bit or 16 bit. Based on your experience, I am guessing that they are 16 bit, because they are usually usually the more problematic. Can you indicate if the issue is with 16 bit inputs or 8 bit? Also can you indicate what bit depth you are setting on the input raster? I tested here with some imgs that I had that were 8 bit and they are fine.

Upon further review, I was able to re create the issue and found a work around. What I did was instead of using the Create Raster Dataset to create an empty dataset, I used the Copy Raster tool to create a copy in the file geodatabase. Once the copy was created, I was able to use the mosaic tool to merge in the remaining 4 band 16 bit imgs. Hope this helps.

Just as a follow up to this, I have found that if I don't define a projection when creating the raster dataset the imagery actually does load properly. If I define a projection when creating the raster dataset, even if it is the same projection as the input data, the data loads as "No Data" values.

This is following my original workflows, not the workaround mentioned by Jeff Swain.

Source imagery is 8 bit tif files.

Thanks for this post.

It saved me a few more days of trouble shooting even though two were already wasted. EXTREMELY frustrating to have functionality deteriorate year after year. (at least 25% of my job time goes to chasing bugs and error codes, and 'not responding')

.....and the bug still exists in 10.2.2

The source imagery can be 8 bit, but if the spatial reference is altered or if the NoData value is specified outside the range of 0-255, then the process will resample the raster. In the resampling, rather than delete data or replace values, the bit depth on the raster will be upgraded to the next bit depth. So if you values run 0-255, a NoData value of say '0' is not set, then the process will make the NoData value 256. Then it will look at the values and upgrade the bit depth. This change from 8 bit to 16 bit usually causes a lot of the loading issues.

I understand your frustration. After checking the status of the bug report, it is still marked as
'assigned', which means it is being actively worked on by a developer. I know that it is not a solution, but know that it is still being worked on and should be resolved in future releases.

Still an issue in 10.3 as well it seems.
