I am working with some data that somebody else prepared. The data consists of DEM .tif files that have been remapped to different values. When I attempt to upload these files to Google Earth Engine via the assets tab, I get the following error:

Error: No data value -128.0 cannot be applied to band #0 of type Short <0, 255>.

Is there any way i can alter the data in QGIS to fix this error?

If the Earth Engine error is correct, the nodata value is incompatible with the data type of your image because -128 cannot be represented in an unsigned integer. You can fix that in QGIS by re-exporting the image with a compatible data type using the Raster > Conversion > Translate (Convert Format) tool.

If the int8 data type isn't supported by your QGIS version (it was added recently), you could either:

  1. Continue using -128 as the nodata value but use an int16 data type. This will make a larger file, but allow you to keep using the same nodata value.
  2. Assign a new nodata value (like 0 or 255) and use a byte data type. Just make sure that the nodata value you choose isn't being used for valid data.

Both of those can be done using the Translate tool.
