Calculate a least squares arc fitted solution to a set of points stored on your device's storage. App scans for, and displays only PNEZD (comma delimited file - Point Number, Northing, Easting, Elevation, Description) formatted text files placed on your device. Each file should contain only those points to be least squares arc fitted. After initial calculation, select point from list to change weight of any point, or choose to include / exclude any point, and recalculate. List shows perpendicular offsets to calculated arc, weighting of each point, and if the point has been included in the solution. Display above list shows radius point coordinates and value of the radius.
