Abstract

Since the recent development of UAVs(Unmanned Aerial Vehicles) and digital sensors technology has enabled the acquisition of high-resolution image data, it is considered that the image data of riverside can be analysed. Therefore, this study analyses the applicability of remote sensing techniques through image analysis in river systems and habitats. The target stream in this study was the Cheongmi stream and the applicability of the river environmental evaluation technique was analysed through image analysis. The satellite images used for the analysis of river topography and environments were compared with the aerial images taken by a micro UAV), and the river environmental evaluation was carried out with the field research at the same time. The data acquisition range and application limit by river environmental evaluation technique proposed previously were evaluated, and as a result, it was found that it was possible to draw various evaluation parameters using a drone that could take an image at a low altitude in comparison to satellite images.
