I've just tried to determine the maximum value for a raster layer using Raster Layer Statistics.

However when I use the tool it produces nan values for the statistics, even though the layer clearly has values.

What would be the likely cause of this?

  • Which QGIS version are you using? If you right-click your raster and go to Properties > Metadata, are statistics such as max, min values shown? – Joseph Sep 4 '17 at 9:12
  • QGIS version 2.18.0, Also I found STATISTICS_MAXIMUM=158143.61367747 STATISTICS_MEAN=29268.402562978 STATISTICS_MINIMUM=0 in the metadata – Mp3Robbo Sep 5 '17 at 22:33
