DETAIL SURVEY
RADIATION BY TACHEOMETRY
Tacheometry is an optical distance measurement method that is capable of providing horizontal and vertical distances at accuracies suitable for detail surveys
-
Distances obtained by tacheometry tacheometry are of low order accuracy, therefore, is suitable to be used for producing plans at scales less than 1 : 200
