I am having problems working with land sat8 imagery in ArcGIS Pro. I keep on getting this image (see attached) and I can't do my land classification with this. Please can any one help.

Thanks

The Band Composite parameters look fine.

Do the individual bands display correctly in ArcGIS Pro?

If they do, then in the composite layer change the band combination to

For True Color Composite

Red Channel: Band 4

Green Channel: Band 3

Blue Channel: Band 2

 

For Standard False Color Composite

Red Channel: Band 5

Green Channel: Band 4

Blue Channel: Band 3

Was this the original landsat image?

Did you add it to an empty map? (eg no topographic layer)

What are the image properties?

Yes it is the original landsat image, I ran the composite tool first and it automatically added it to the topographic map. I have attached a screenshot the properties.

Do you have the individual band rasters? Landsat 8 band designations (usgs.gov)

What bands were used while creating the composite, and in what order?

Please share the screenshot of the parameters used in Composite Bands tool.

Thanks for responding. I have attached a screenshot as requested. I made sure they were in order before running the composite band tool.

If it is the original landsat image, it would already be composite bands.  

Why would you run the tool if it already had 3 or more bands? (it has 7 bands now)

Is this the original image?  not the one with composite bands run on it.

Landsat8 images comes as individual bands. See attached screenshot.

ahhhh no wonder it looks strange to me

Landsat 8 bands 4, 3, and 2 correspond to the red, green, and blue portions of the visible spectrum.
