OPTIMIZATION OF GROUND CONTROL POINT (GCP) CONFIGURATION FOR UNMANNED AERIAL VEHICLE (UAV) SURVEY USING STRUCTURE FROM MOTION (SFM) [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Abstract. This research presents a method in assessing the impact of Ground Control Point (GCP) distribution, quantity, and inter-GCP distances on the output Digital Elevation Model (DEM) by utilizing SfM and GIS. The study was carried out in a quarry site to assess the impacts of these parameters on the accuracy of accurate volumetric measurements UAV

Semi-Automatic Selection of Ground Control Points for High Resolution Remote Sensing Data in Urban Areas

open access: yesApplied Computer Systems, 2016
Geometrical accuracy of remote sensing data often is ensured by geometrical transforms based on Ground Control Points (GCPs). Manual selection of GCP is a time-consuming process, which requires some sort of automation. Therefore, the aim of this study is

Automatic selection of permanent scatterers-based GCPs for refinement and reflattening in InSAR DEM generation

open access: yesInternational Journal of Digital Earth, 2022
In DEM generation using interferometric synthetic aperture radar (InSAR), the ground control points (GCPs) for refinement and reflattening are usually selected by manual selection, field surveying, GPS points and existing basemaps, which may not be ...

ANALISIS PENGARUH SEBARAN GCP (GROUND CONTROL POINT) TERHADAP AKURASI HASIL ORTHOPHOTO DI PIT CENDANA PT KALIMANTAN PRIMA PERSADA SITE BRE [PDF]

open access: yesJurnal GEOSAPTA, 2019
Kelemahan dari foto udara adalah masih belum didapatkannya cara yang bisa membuat tingkat akurasi dari hasil proses foto udara itu sendiri menjadi memilki tingkat akurasi yang tinggi dan masih belum bisa diperkirakan seberapa baik tingkat akurasi yang akan didapatkan dari proses foto udara itu sendiri. Namun keuntungan dari foto udara ini sendiri yaitu

GEOMETRIC CALIBRATION OF ZIYUAN-3 THREE-LINE CAMERAS COMBINING GROUND CONTROL POINTS AND LINES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Due to the large biases between the laboratory-calibrated values of the orientation parameters and their in-orbit true values, the initial direct georeferencing accuracy of the Ziyuan-3 (ZY-3) three-line camera (TLC) images can only reach the kilometre ...
