WebbTwo simple curves Depending on which parts are initially fixed, there are different ways to compute the remaining parts. One way is solving the vertex triangle, Figure D-12, created by the three PIs. Figure D-12 Vertex triangle Another method is to use a closed loop traverse through points O 1 -BC 1 -PI-EC 2 -O 2, Figure D-13. Figure D-13 Webb18 juni 2012 · The theory of a recently developed method of curve ranging known as the Optimum Point Method (OPM) is reviewed. Among the advantages of the OPM is its ability to provide on-the-spot solution to most types of obstruction encountered in the field.

The interval between the peg is usually 20 to 30 m. strictly speaking this interval must be measured as the arch intercept between them. However as it is necessarily measured along the chord, the curve consist of series of a chord rather than of arcs. dfw weather live stream
