Creation and Assessment of a Topographic Map from Unmanned Aerial Vehicle Data in the Province Phu Tho, Thanh Son District

In recent years, there has been a rapid advancement in the use of unmanned aerial vehicles (UAVs) various aspects life, especially area automated data collection. These advancements have brought about numerous possibilities. The article describes an vehicle, specifically PHANTOM 4 pro, to gather remote sensing and create digital topographic plans at scale 1:2000 Phu Tho province's Thanh Son district. A method was suggested for improving current systems obtaining cartography using UAVs. ease controlling UAVs quality timeliness they transmit control points confirm value them maps. addition UAVs, fieldwork also involves GNSS brand CHCNAV I50. high precision system enables camera's 3D position be detected within few centimeters time each capture. map compiled district, covering 165 hectares, processed software such as Agisoft Global Mapper. that produced satisfies documentation requirements government organizations. maximum error height is 4.7 cm, coordinates north east are 1.8 cm 1.4 respectively. This achieved by 590 raster images, which had resolution 2.3 size 5472x3648 pixels. Based on findings, map's accuracy acceptable range less than 2 suitable 1:2000.
