Zero designates a loop that is flat on the ground, whereas 90 is a vertical loop. This value in turn with azimuth allows for arbitrary orientation of the loops. If azimuth is zero, and dip is 90, the loop has a normal aligned in the northing direction. </p></body></html> 90.000000000000000 1 100000 Qt::Horizontal QDialogButtonBox::Cancel|QDialogButtonBox::Ok turns -999999999.000000000000000 9999999999.000000000000000 <html><head/><body><p>Currently Akvo/Merlin calculates circular loops using segments of wire, forming a polygon.
