Development of digital elevation model for small catchment area using UAiCs technology

摘要

This paper has discuss the image processing of aerial photograph acquired from unmanned aerial imagery capturing system (UAiCs) in generating a digital orthophoto and digital elevation model of a small catchment. The purpose of the study is to produce a recent digital elevation model of the study area which comprise of terrain and water bodies particularly in depicting river water level during rainy season. The process of handling the UAiCs including the preparation stage for flight planning and the actual flight mission were also discussed. The end result shows the digital orthophoto product as well as digital elevation model of the catchment area that ready to be used for further analysis.
