Předmětem článku je zpráva o cílech, teoretických a metodologických základech a dosavadním průběhu výzkumného projektu zaměřeného na aplikaci leteckého laserového (lidarového) skenování – nejnovější metody dálkového archeologického průzkumu a 3D (výškopisného) mapování zemského povrchu s výskytem nemovitých archeologických památek. Projekt jako první svého druhu na území České republiky je koncipován tak, aby prokázal potenciál uvedené metody a jeho efektivitu z hlediska identifikace a dokumentace nemovitého archeologického dědictví v jeho kvalitativní (druhové) rozmanitosti a v různorodých krajinných typech (lesní prostředí, otevřená krajina, nížina včetně intenzivně oraných ploch, pahorkatina), a také ve srovnání s klasickým geodetickým zaměřováním památek. and Archaeological remote sensing by means of airborne laser scanning. Interim report upon the first lidar research project in Bohemia. This paper brings report upon the goals, theoretical and methodological bases and current state of a research project which aims at the application of airborne laser (lidar) scanning (ALS) – the most recent sophisticated method of remote sensing used for the identification and 3D documentation of landscapes (terrain surfaces) containing prehistoric and ancient sites and monuments, specifically earthworks. As the very first project of this kind in the Czech Republic it is expected that the potential of this method and its effectiveness from the perspective of both identification and documentation of archaeological heritage, namely in terms of sites and monuments variability and placement in different landscape types (such as woodland, open landscape, lowland including cultivated fields, upland) will be recognized. Also, a comparison of costs between ALS and terrestrial survey of a site will be checked in the final section of the paper.
Southern Poland, especially Polish Carpathians, is a region affected by strong mass-movements. The importance of massmovements problems has been taken into consideration on the governmental level and Landslide Counteracting System (SOPO) program was launched in 2008. The main purpose of this program is to create inventory and map all active and inactive landslides and landslide prone areas in Poland. However, in case of such gigantic work, the traditional mapping methods meet sometimes their limitations. In order to overcome some of efficiency problems the new technology, the application of airborne laser scanning was tested. The main purpose of presented work is to test whether the LiDAR DTM is capable to support geological interpretation and landslide detection on steep and forested slopes for the purposes of landslide mapping within SOPO project. For this purpose the ALS dataset covering 40 km2 of the area near Roznow Lake in Polish Carpathians have been acquired in April 2010. The average scanning resolution was 7 points/m2 and LiteMapper 6800i system based on the full waveform, Riegl LMS-Q680i scanner have been used. Acquired point cloud was applied to generate DTM of 0.5 m resolution. For efficiency test purposes the detailed geological interpretation of constructed ALS DTM was focused on already well mapped large Zbyszyce landslide. The extents of the landslide and the zones of different level of activity have been mapped and then verified with field data. During the detailed analysis it was found that the level of the details of ALS DTM allows also performing morphometric analysis on landslides., Andrzej Borokowski, Zbigniew Perski, Tomasz Wojciechowski, Grzegorz Jóźków and Antoni Wójcik., and Obsahuje bibliografii
