EDM Calculator

EDM Calculator™ offers you the Site Civil Engineer/Engineering Surveyor, the majority of any

Co-ordinate Setting-Out computations you may wish to carry out, covered by 3 online programs

that cover Whole Circle Bearing, Straight Road/Line and Circular Road/Curve. Whether you

use it as your primary calculator or even as a counter check against your own calculations,

EDM Calculator™ is unique.

EDM Calculator - Whole Circle Bearing

Whole Circle Bearing

This calculates the Horizontal Distance (Hd) & Bearing (WCB)

from the Instrument Set Up Point (N,E) to any known Target

Points (N,E)

X

EDM Calculator - Straight Road/Line

Straight Road/Line

This calculates the Northings & Eastings at any Chainage,

along the Centre Line from any Start Point (TP1) to any

Finish Point (TP2)

and

calculates the Northings & Eastings to any offset widths to the

Right & Left of the Centre Line, which are at 90 degrees to the

Centre Line

and

calculates the Horizontal Distance (Hd) & Bearing (WCB) to any

of the above Chainage Centre Line Points & Offset Points, from

the Instrument Set Up Point (N,E)

and

calculates the Bearing from the Start Point (TP1) to the Finish

Point (TP2) with the Length between these 2 points

X

EDM Calculator - Circular Road / Circle

Circular Road/Curve

This calculates the Northings & Eastings at any Chainage, along

the Centre Line, from any Start Point (TP1) to any Finish Point

(TP1) for any Radius

and

calculates the Northings & Eastings to any offset widths to the

Right & Left of the Centre Line which are at 90 degrees to the

 Centre Line and the Radial Point

and

calculates the Horizontal Distance (Hd) & Bearing (WCB) to any

of the above Chainage Centre Line Points & Offset Points,

 from the Instrument Set Up Point

and

calculates the Approach Bearing, the Exit Bearing, the Length

of Curve, Long Chord, Rise, Co-ordinate Value of the Curve

Centre & Deflection Angle.
