I have thousands of points in multiple shapefiles. I want to get the maximum value of an attribute of each shapefile. Then I want to merge all the maximum values to a new layer.
Is there a way to extract max values as a batch process from multiple layers?
This is the sample attribute table. The max values I need are from "DTM50austri" from each Shapefile.
This is the query I've tried. "Zusammengeführt" is the merged shapefile.
