05. BUILDING THEMATIC MAP USING UAV TECHNOLOGY FOR WATER SUPPLY AND DRAINAGE PLANNING IN THE CASE STUDY OF HAI PHONG CITY

Tóm tắt

Thematic maps are crucial representations that depict specific natural and socioeconomic phenomena. Unmanned Aerial Vehicles (UAVs) offer several advantages, including high resolution, accuracy, rapid image processing, easy 3D data creation, and cost-effectiveness. UAV technology is highly suitable for mapping small or inaccessible survey areas using direct measurement methods. This article aims to establish a thematic map using UAV technology for urban water supply and drainage planning, focusing on the case study of Le Chan district in Hai Phong city. The steps involve image capture, control point surveys, image block processing, thematic map establishment, and accuracy assessment. This resultant map for water supply and drainage planning will significantly contribute to effective and sustainable planning and exploitation of the case study in the near future.
