Hi,
Notice the selection box besides "Précision". You will see "Estimée
(plus rapide)", Change that to "Actual (slower)". Then, if you choose
min/max, you should see the correct values. If you don't see the
correct min-max value, open processing/Raster information/ select
"Force computation of the actual min/max values for each band". add
-stats in the additional command-line parameters.
Bonne Chance

Hi Nicolas,
Thanks a lot for your help. I am using the QGIS idk interpolation. I
think I figured out a way to get the results fitting my data
adjusting min and max values from the dataset. When I get the
output, I can change the min and max values in the symbology tab. Is
that the way you would recommend?
Thanks a lot for your assistance.
Best,

Hi,
It would help if you gave what algorithms you are using. There is
a Gdal and a QGIS idw interpolation method and they are not working
the same way. Also, QGIS has a quick way of determining the min
max value that are an estimate of the true values. Use Gdal info
with flag -stats to get the true values. You will find that in the
processing plugin.

Hi everyone,
I am trying to make an IDW interpolation analyses using salinity
data in a bay. My values ranges between 0.1 to 13.1 PSU. When
making my interpolation with 148 data points, the interpolation
output ranges between 0.0034 to 12.40 and so doesn't fit 100% with
the dataset. Can someone has na idea why? Using the same data set
in ArcMap, the interpolation I made ranged between 0.1 and 13.1
and does fit 100% with my dataset.
Thanks a lot for your assistance,
Best,
Thibaut
