When asking to R, I get the real min/max values. QGIS, instead, calculates the min/max values with a cumulative count. When I set the "Load min/max values" (in the Raster Properties window) to "Min/Max" I got the same values R showed. Share Improve this answer Follow answered No...

Now we are ready to extract the values from the raster layer at these points. Go to Processing ‣ Toolbox. Search and locate the Raster analysis ‣ Sample raster values algorithm. Double-click to launch it. Select 2018_Gaz_ua_national as the Input Point Layer. Select us.tmax_nohads_...

imo at least there should be a warning clearly stating an unsupported or broken file - bonus points for stating that it comes from an unsupported QGIS version. also i would imagine this behavior does point to another underlying issue with the way symbologies are applied, but i couldn't ...
heatmap result in QGIS You may ask, why the values are not integer. According to the filter we have used, points near a certain location have bigger influence than points far away a given location. So the points are weighted in their influence. This is useful as we might have an underly...

This setting ensured that sampling the same pixel twice would be prevented; moreover, it helped to better distribute the sampling points across the study area. The next step was to extract ETo (or MODIS ET) values to points from each one of the raster inputs (see Table 3), and then ...
10.Interpolation– Interpolation techniques estimate unknown values based on existing sample points. The output of interpolation (such asIDW,kriging, or spline) is a raster surface. If you’re looking for more examples of raster tools, here are more examples in theRaster Analysis Toolbox in ArcGI...
