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

Applied 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

Multifunctional Ground Control Points with a Wireless Network for Communication with a UAV

Sensors, 2019
Ground control points (GCPs) are commonly used for georeferencing in remote sensing. Precise position measurement of the GCPs typically requires careful ground surveying, which is time-consuming and labor-intensive and thus excessively costly if it needs

Harmonizing the Landsat Ground Reference with the Sentinel-2 Global Reference Image Using Space-Based Bundle Adjustment

Remote Sensing, 2020
There is an ever-increasing need to use an accurate and consistent geometric ground reference in the processing of remotely sensed data products, as this reduces the burden on the end-users to account for the differences between the data products from ...

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

International 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]

Jurnal 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]

The 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 ...

Generation of a Digital Terrain Model (DTM) Fusioning WV-2 Images and RTK-derived Topobathymetric Data

Revista Brasileira de Cartografia
Digital terrain models (DTMs) are digital elevation models (DEMs) that represent the bare ground surface. They are created by multiple sources, including satellite remote sensing, aerial photography, and ground-based surveys, and are often combined with
