Raster band statistics type error

[mloranty]

Hello,

I receive the following error when attempting to run the Geo-SAM Image Encoder. This is on a PC, the encoder will run on this image on my Mac, and it will also run on either platform on a clipped subset of the image created in QGIS. Any ideas on how I can get the encoder to run on the entire image would be appreciated. Thanks!

Hi there, just an update to note that this error seems to be occurring only when NoData areas beyond the edge of the image are included. If the extent for image encoding is reduced to a rectangle within the image area the encoder runs (as shown below). But for the whole image encoding fails with the error shown above, but only on PC.

Hi @mloranty

When using QGIS to calculate the maximum and minimum values of an image, if there are NaN values present, the maximum and minimum values will also become NaN. Currently, there are two solutions:

1. Manually set the maximum and minimum values of the image value range.

2. Use GeoSAM-Image-Encoder (Python package), which calculates the maximum and minimum values using NumPy and does not have this issue.

This is great, thanks so much!
