These points are employed in the overlap analysis and map registration of possible parcel points and digitalized cadastral maps to identify the coordinates of parcel points. Based on the computed horizontal distance and angle between control points and parcel points, parcels are staked out using ground surveys. Most studies survey possible parcel points using ground surveys with, for example, total stations. Compared with ground surveys, UAV (Unmanned Aerial Vehicle) aerial photogrammetry can provide more possible parcel points. Thus, an overlap analysis of digitalized cadastral maps, combined with the collection of possible parcel points, will be more comprehensive. In this study, a high-quality-medium format camera, with a 55 mm focal length, was carried on a rotary UAV to take images, with a 3 cm ground sampling distance (GSD), flying 300 m above the ground. The images were taken with an 80% end-lap and side-lap to increase the visibility of the terrain details for stereo-mapping. According to the test conducted in this study, UAV aerial photogrammetry can accurately provide supplementary control points and assist in the boundary verification of digitalized cadastral areas in Taiwan. 關聯 Remote Sensing, 12(10), 1682 資料類型 article DOI https://doi.org/10.3390/rs12101682 dc.contributor 地政系 - dc.creator (作者) 邱式鴻 - dc.creator (作者) Chio, Shih-Hong - dc.creator (作者) Chiang, Cheng-Chu - dc.date (日期) 2020-05 - dc.date.accessioned 2022-07-04 - dc.date.available 2022-07-04 - dc.date.issued (上傳時間) 2022-07-04 - dc.identifier.uri (URI) http://nccur.lib.nccu.edu.tw/handle/140.119/140757 - dc.description.abstract (摘要) In conducting land boundary verification surveys in digitalized cadastral areas in Taiwan, possible parcel points must be surveyed.
