I have two raster files and I want to merge them in QGIS. The first raster has values between 0 to 8627 and the second one has 0 to 9118. However, when I do it with the Merge tool (in GDAL/raster miscellaneous) new raster's values are between 0 to 9,260. Somehow, it is rescaled or some raster values are combined. When I checked the map, only one raster is rescaled but the other one stayed as original.

Do you have any suggestions? here is the tools parameters

    If you are just looking at the min/max values in layer legends in the QGIS Layers tab, your original max values (8627 and 9118) are likely estimated, not actual max.

  • Oh yes, I change them via Symbology>Min Max Values Settings>Accuracy>Actual(slower) So there was no problem, just the max min values were poorly estimated.

By default, QGIS shows estimated min and max values in the layer legend (faster). To see the actual values, in the raster layer properties, symbology tab, change "Accuracy" from "Estimate (faster)" to "Actual (slower)".
