ABSTRACT

The aim of the paper is to introduce the surveying and evaluating the historic crane runway in the Karany water treatment plant. The crane runway was built in 1911 and is operated to the present without any major modifications. The aim of the geodetic survey was the control of the directional and vertical straightness of rails and the rail gauge. Accuracy analyzes and deviations evaluation were performed in accordance with technical standard CSN 73 5130. The runway was measured by two different methods. The first method was measurement in the local geodetic network with three standpoints. Automatic targeting to prisms was used, and the least squares adjustment was performed. The second method of measurement was laser scanning by multistation Leica MS60 from 14 standpoints and then evaluation of the point cloud and determination the parameters of the crane runway. Comparable results were obtained from both methods.
