Możliwości wykorzystania danych z lotniczego skanowania laserowego do modelowania rzeźby dna projektowanego zbiornika wodnego Pietraszki (Kielce)
Possibilities of airborne laser scanning data use for modelling of the designed Pietraszki water reservoir bottom relief (Kielce)

Summary/Abstract: The paper presents the possibilities of the airborne laser scanning (ALS) data use in the morphological analysis of the bottom of the designed Pietraszki multi-purpose water reservoir, which is located in the mouth section of the Sufraganiec river (5th rank) in Kielce. The source material consisted of 0.5 m resolution digital terrain model created by the MGGP Aero company on the base of ALS point cloud obtained in 2011. The analysis was performed in SAGA GIS software and included modelling of the Sufraaniec valley bottom, where the reservoir’s coastline was outlined, and a calculation of the reservoir’s geometrical and morphological parameters. A practical effect of the analysis was the estimation of the ground masses volume that need to be moved in the investment area and also the designation of recreational zones along the reservoir’s coastline. The performed analysis demonstrates the legitimacy of ALS digital terrain model use in detailed modelling of the planned reservoir bottom and also in outlining its coastline reach at the designed water levels.
