COGO Calculations • End Point/Azimuth – the ending point of the line / the azimuth to another point: either enter manually or select from the map or from the list. • Ht Comp – select the type of height computations for the calculated points from one of the following: – Interpolate Ht: the height of the calculated point will be computed through linear interpolation using the height of the starting and ending points of the line. – Ht of Start Pt (height of starting point): the calculated point will have the same height as the starting point of the line. • Num Subs – check and enable to designate the number of subdivisions you want to subdivide the line. For instance, a value of 3 indicates a calculation of four points by subdividing the line into three equal segments. • SS (Start Sta) – enter the starting station (chainage) of the line. • Next – opens the Station (Chainage) & Offsets screen. Station & Offset The Sta&Ofst screen (Figure 14-52) contains the settings for the calculated stations with offsets from the line. Figure 14-52. Station & Offsets 14-40 TopSURV Reference Manual
