Mapping is the process of presenting information about the earth's surface in the form of facts, including the shape of the earth's surface and its natural resources based on scale, projection systems, as well as various symbols and emblems of the elements on earth. Mapping using a Small Unmanned Aerial Vehicle (SUAV) is a process of making maps using aerial photos with high resolution images, faster and more efficient compared to conventional methods.
This research is a field study on the Lake Tondano Ring Road Section STA 21+100 – STA 44+200, Minahasa Regency, North Sulawesi. Field data collection uses a Small Unmanned Aerial Vehicle (UAV) for aerial photos and Geodetic GPS. Drones are needed to capture area objects, while Ground Control Point (GCP) measurements use the Real-Time Kinematic (RTK) method.
The results of research conducted on the Lake Tondano Ring Road Section STA 21+100 – STA 44+200 produced a spatial resolution of 11.7 Cm/Pix. From the results of the planimetric coordinate accuracy test results from aerial photo mapping, it was found that the CE90 value was 0.003 m and the LE90 value was 0.004 m, which means that the horizontal accuracy test results of the map accuracy met the 1:1000 scale, namely entering class 1 with a maximum accuracy of 0.3 m. Mapping surveys using the Small Unmanned Aerial Vehicle (SUAV) method are much faster and more efficient, unlike conventional methods. The length of the mapped road, namely 22.1 kilometers, was completed in 4 days, compared to conventional methods which can take ± 20 days.
