Greetings,
I am working on a project in ArcGIS Pro with aerial imagery collections in GeoTIFF format. When the individual images were downloaded from a 3rd party site, the symbology was not consistent throughout the collection. I’m trying to assign a set of common custom statistics values to each image so they will all have the same Stretch Type and RGB Min/Max statistics values. However, I’ve encountered an issue with custom symbology where ArcGIS Pro drops the selected Minimum/Maximum Stretch Type and reset the custom statistics values I entered to the original system-generated statistics assigned when the Calculate Statistics tool was run. The issue exists with all the GeoTIFF images in the project.
Steps to repro:
- I downloaded several Ariel imagery GeoTiffs from the Maryland GIS portal and saved them to a local folder on the same machine where ArcGIS Pro is installed.
- From ArcGIS Pro -> open the Catalog pane -> browse to folders with GeoTiffs.
- RMB on GeoTIFF -> select Calculation Statistics from the RMB menu -> let the tool run so the raster GeoTIFF displays in the ArcGIS Pro Contents pane.
- I start from the ArcGIS Pro -> Catalog folder directory to load the images. I browse to the folder where the images are stored, select an image -> RMB, then select ‘Calculate Statistics from the menu.

5. After Calculate Statistics is done, the GeoTIFF appears in the Contents file directory. I expand the file and select one of the RGB bands to open the Primary Symbology form. (Note that Symbology has the system-generated statistics populated).

6. I change the Statistics from Dataset to Custom then enter the custom statistics values that should be common across all images.

7. Everything looks good at this point, but if I take the focus off this file, then place focus back on the file, the Minimum/Maximum Stretch Type has been deleted, and the RGB bands with the custom statistics populated have been duplicated so there's 6 bands instead of 3.

8. If I repopulate the Stretch Type field with Minimum/Maximum, the custom statistics are replaced by the system-generated statistics.

This is incredibly frustrating. What am I missing in this workflow that's causing this issue?
Thanks in advance for any help on this!!
Matt
