Opportunities and Challenges of UAV Application for Monitoring the Construction Progress and Updating the Geographic Database in Urban Area of Ho Chi Minh City, Vietnam

Abstract

Abstract Authorities of the Ho Chi Minh City have expressed an interest in developing application solutions of UAV (Unmanned Aerial Vehicle) that are able to monitor construction progress at different stages of any project; and to update cadastral maps for improving geospatial information for decision-making. This paper aims to describe new opportunities of using UAV in monitoring and mapping at Thu Duc district, and to address main challenges from different aspects and limitations that help engineers to improve the procedures and accuracy of UAV images processing. Some specific application cases focused on monitoring construction progress, cadastral mapping and updating the database are also introduced for understanding how UAV solutions can be applied as one tool to improve the analysis of land use change and infrastructure management in the urban area. In addition, the analysed results also shown how to develop the flight planning and the suitable Ground Control Points (GCPs) with challenges from different aspects in application solutions in capturing necessary data on monitoring construction progress and updating cadastral maps with large scale (1:200 and 1:500).
