Hi list, I just used the area()-Function to calculate the area of a polygon them and was surprised, as all values were negative. The absolute value was correct, "only" the minus is very strange. The layers I tested were from our official database. I am confused by this, as determinating the area using the measure tool results in the correct value (without "-"). Moreover, if I use the "split"-tool and recalculate the area, the area of the splitted geometries is positive (the rest remains negative). Very strange. Any ideas are appreciated very much. Best, Wolfgang --
