What version of ENVI are you using and what tool are you using?

Hi, I am using ENVI 5.3.2 Rev 309742, bld: 4/6/2016 I am using the Resize Data tool in Raster Management.

So you are just trying to change the pixel size? What do you mean by 8->1? A pixel resize of 8m to 1m? Is the input data in ENVI format or another? Are you saving the result to the same directory as the input image and if so, do they have the same name? Does this behavior occur with other images? For example, with ENVI's sample dataset qb_boulder_msi found in the \Exelis\ENVI53\data directory?

Yes I am resampling to speed up a subsequent task in the workflow. I am using an xfac and yfac of 0.125 (1/8) and cubic convolution.I save to a file and use a different name indicating the new resolution.I have had this happen on more than one file, but of course the one I tried just now behaved as expected. I try to reproduce the problem. If it works on my original data - great - I will shrug this off. If not, I will look closer at the problem. Thanks,

Hi, So I tried again with another raster and I still get a vertical slice and swap. Maybe this happens only when I operate on the whole image? I tried a null-resizing (x and yfactor = 1.0) and it still did the same thing.I will keep trying and post any results.

Hi, Another observation. If I go immediately from entering my xfac and yfac (in my case each equals 0.125) to the resampling method, the resampling methods are those for interpolating. Cubic convolution should not be available when my factors are less than 1. If I twiddle the button again, the proper methods for down-sampling show up. The resampling loks right, but I still get the sliced and swapped output.

Can you post the header file of the image you are trying to resize? I can generate some dummy data and try to reproduce the issue. Note that in the Resize data dialog, you must select 'enter' for the entry to register in the dialog and adjust the parameters

Say what?

Hi, I'm trying to use the "document manager" in the Rich Text Editor to attach a .hdr, but I can't see my files or navigate around. I had been just bringing in a geotif and trying to resize. If I save it out in ENVI format, and operate on that data, the problem does not occur. So, that is what I would call a work-around; maybe that is a step I should always be doing?Do you have any interest in seeing why the geotiff behaves this way? If so I will have to get the file to you via another route.Thanks,

Yeah, I was just going to have you copy/paste the contents of the header but if the input is only a problem in another format such as TIFF, we can try to reproduce another way. For example, if you open ENVI's sample dataset qb_boulder_msi (under the ENVIxx\data directory) and save this to TIFF. Then try the same process, do you see the behavior? The Resize data tool has been in ENVI for ages and the only time I have seen this sort of behavior is if the TIFF and ENVI file result end up in the same directory with the same name. In ENVI Classic, opening the TIFF would also read the ENVI format file .hdr and cause weird offsets and such.
