Engineering Surveyor Programsfor Casio fx-7400G & fx-9860GIIOFFSETIntroductionThis program calculates the perpendicular distance (offset) of a point from agiven baseline, as well as the distance along the baseline to that perpendicularintersection (chainage).Positive offsets are to the RIGHT of the line and negative offsets are to the LEFTof the line.Note: Chainages can also be negative.DiagramDirection of BaselineE2, N2E3, N3NEGATIVEOffsetPOSITIVEOffsetChainageChainageE3, N3E1, N1InputBaseline co-ordinates: (E1, N1) (E2, N2)Other points: (E3, N3)OutputOffset:Chainage:+/- OffsetChainagePage 24 of 47
