The route and duration of perpendiculars needs to be established out with wonderful accuracy. The check can be produced by measuring diagonals with the rectangles. For the same rectangle, diagonals really should be equivalent. In this article Advert must be equal to BC, and EH equivalent to FG.
The impediment of this sort may be crossed above by “Random line strategy”. In fig. three.20, let AB be the line whose length is required. From A, run a line AB’ identified as a random line, in the approximate hassle-free course of AB and continue it right up until place B is obvious from B’ Chain the road to B’ where BB’ is perpendicular to AB’ and measure BB’.

The combination of historic rules and rising systems in Bangladesh’s surveying training mirrors the region’s journey – rooted in abundant traditions nonetheless dynamically evolving toward a technologically advanced long term.
Land surveying can be a historic job with a lengthy legacy of exact measurements employing applications and procedures proven over the years to establish property boundaries. Adopting electronic land surveying and rugged technologies solutions could possibly be observed as disruptive to that legacy. Prolonged-time professional land surveyors have to find out how to implement rugged technological know-how and electronic land surveying procedures, which some may view as challenging.
