Surveying methods for levees inventory on the example of Vistula Boulevards in Cracow

Abstrakt

Geodetic works carried out for the purposes of evaluation of technical condition of flood embankments have to meet some special technical criteria. Modern technologies such as classical measurements, the photogrammetric studies and laser scanning have been taken into consideration in the paper. The presented method follows a hybrid approach by integration of classical measurements, scanning function of reflectorless tachymeter and camera images. Experiences based on geodetic inventory of the Vistula Boulevards in Cracow conducted in 2010 r allows to determine the usability of above mentioned methods in this specific measurements. It has been found that in the case of inventory of earth structures the optimal method of measurement needs combining classical methods and scanning tachymeter. The proposed hybrid method is also effective when applied for typical concrete constructions. Using of laser scanners is justified only in the case of measurement of very complicated structure.
