Comprehensive Analysis of UAV Flight Parameters for High Resolution Topographic Mapping

EasyChair Preprint 4116

Abstract

Unmanned Aerial Vehicles (UAVs) are aircraft without pilot onboard which being controlled by ground station. The ability of UAV provide high resolution imageries and accurate positioning make it is the best platform compared to satellite image. Therefore, UAV can speed up the topographic works especially during data collection. Topographic mapping has been used by many agencies such as government, private and military. Furthermore, the geotagged high resolution UAV images can provide accurate results using Ground Control Points (GCPs). UAV flight parameters such as flight altitude, percentage of overlap and sidelap can effect the topographic map result derived from UAV images. The optimal flight altitude, overlap and sidelap percentage based on specific topographic surface need to be investigated in order to produce accurate topographic map. The aim of this study is to assess the accuracy topographic map from different flight parameters. There are two objectives to achieve the aim i.e. to produce photogrammetric products from different altitude, overlap, sidelap and analyze the photogrammetric products with ground survey data. In this study, the selected flight altitude in this study are 60m, 80m and 100m. However, the percentage of overlap are 70%, 80%, 90% and percentage of sidelap are 50%, 60% and 70%. GCPs and Check Point (CPs) will be established using Global Navigation Satellite System (GNSS) techniques where the Global Positioning System (GPS) receiver capable of Real-Time Kinematic (RTK) in order to receive the real time data correction from Continuously Operating Reference Station (CORS) in different locations. This study will analyze the topographic results at different flight altitude, percentage of overlap and sidelap using Root Mean Square Error (RMSE). The expected outcome of this study includes comparison coordinates between CPs coordinates and ground survey data coordinates, different Digital Terrain Model (DTM) and different topographic map.
