Abstract

Predmet istraživanja ovog diplomskog rada izrada je inventara klizišta primjenom LiDAR tehnologije na pilot području u Gornjoj Dubravi, Grad Zagreb. Prednost LiDAR tehnologije u odnosu na ostale metode daljinskih istraživanja je izrada digitalnog modela terena (DMT) vrlo visoke rezolucije bez vegetacije koji omogućuje identifikaciju i kartiranje klizišta na područjima pod gustom vegetacijom i nedostupnim terenima. Inventar klizišta za pilot područje površine 19 km² dobiven je vizualnom interpretacijom morfometrijskih karata izvedenih iz LiDAR DMT-a, a to su karta osjenčanosti terena, karta nagiba terena i karta slojnica ekvidistance 1 m. Inventar klizišta sadrži 730 klizišta, površine od 14,86 do 10.045,28 m2, a najučestalija veličina klizišta je 255,66 m2. Inventar klizišta izrađen u ovom radu uspoređen je s već postojećim inventarom iz 2007. godine te je provedena terenska verifikacija manjeg broja klizišta. Provedena je analiza procjene rizika klizanja za elemente pod rizikom, odnosno kolika je ugroženost od pojedinačnih klizišta na pilot području. Analiza je pokazala kako je na pilot području od klizišta ugroženo 424 građevine i 11 km duljine prometnica, odnosno da se na građevinskom području unutar pilot područja nalazi ukupno 315 klizišta, odnosno 43,19 % od ukupnog broja klizišta u inventaru. Iz svega navedenog proizlazi da LiDAR DMT visoke rezolucije, dobiven laserskim skeniranjem iz zraka, omogućava pouzdanu vizualnu interpretaciju klizišta i izradu detaljnog i potpunog inventara klizišta kojeg je moguće koristiti i u drugim analizama, kao i u prostornom planiranju te za potrebe sustava civilne zaštite.

Abstract (english)

The research subject in this master's thesis is the creation of an inventory of landslides using LiDAR technology in the pilot area in Gornja Dubrava, City of Zagreb. The advantage of LiDAR technology compared to other remote sensing methods is the creation of a digital terrain model (DMT) of very high resolution without vegetation, which enables the identification and mapping of landslides in areas under dense vegetation and inaccessible terrain. Landslide inventory for the pilot area of 19 km² was obtained by visual interpretation of morphometric maps derived from LiDAR DMT, and those are the hillshade map, the slope map and the contour map with an equidistance of 1 m. The landslide inventory contains 730 landslides, with surfaces ranging from 14,86 to 10.045,28 m², and the most common landslide size is 255,66 m². The inventory created in this thesis was compared with the existing geomorphological inventory from 2007, and a small number of landslides was verified on-site. A landslide risk assessment analysis was performed for elements at risk, i.e. the risk of individual landslides in the pilot area. The analysis showed that in the pilot area, 424 buildings and 11 km of roads are threatened by landslides; also, there is a total of 315 landslides in the construction area within the pilot area or 43,19 % of the total number of landslides in the inventory. From all of the above, it follows that high-resolution LiDAR DMT, obtained by airborne laser scanning, enables a reliable visual interpretation of landslides and the creation of a detailed and complete inventory of landslides that can be used in other analyses, as well as in physical planning and for the needs of the civil protection system.
