https://community.esri.com/t5/arcgis-pro-questions/mosaic-dataset-statistics-doesn-t-match-up-with-a/m-p/1283396#M68478 <P>I am having a problem with the mosaic dataset showing an incorrect data range (max:127, min: -128) for a signed 8-bit Tiff file (maxi: 31, min: -31, see the image below). There was no problem when I added the original Tiff file which was a signed 16-bit. However, it didn't work well when I publish it online to visualize time series. I have 50 Tiff files in a mosaic dataset so no wonder.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="MakikoShukunobe1_0-1682610082147.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/69315iBA050596F1C1CF3D/image-size/medium?v=v2&amp;px=400" role="button" title="MakikoShukunobe1_0-1682610082147.png" alt="MakikoShukunobe1_0-1682610082147.png" /></span></P><P>My first question would be am I doing wrong converting signed 16-bit to signed 8-bit?
