Hi all, I have raster data for a single, continuous variable (e.g. tmean in May) for a particular region of interest. I'd like to visualize the progression of May tmean across several years with a grayscale or color ramp, to show how it changes through time.
qGIS by default stretches and clips each raster's grayscale ramp to the Min and Max values for that raster. So each ramp has different Min/Max, complicating comparison between years. I thus want to standardize the Min/Max values across the entire dataset. The only way I've found to do this is to determine the Max and Min values for the entire dataset, then enter those Min/Max values in Layer Properties>Style for each raster. This is obviously impractical for large datasets (even for small ones, really). How do I do this correctly, so I can easily generate visual timeseries of a variable of interest? Many thanks in advance, Dave -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Visualize-Raster-Timeseries-with-Standard-Min-Max-Values-tp4510586p4510586.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user
