Extraction of ground control points (GCPs) from synthetic aperture radar image using DEM

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Synthetic aperture radar (SAR) data have serious geometric distortions caused by inherent side looking geometry and are usually corrupted by speckle noises so that it is difficult to identify ground control points (GCPs). The location of the pixel in a given SAR image can be derived from the knowledge of sensor position and velocity.

An automatic ground control point matching based on GCP chip database for remote sensing images

2009 International Conference on Image Analysis and Signal Processing, 2009
With the rapid development of remote sensing technology and comprehensive applications, there are more demands on precision and efficiency for remote sensing digital orthographic maps (DOM). Selecting and positioning ground control points (GCP) is one of the most important parts of geometry correction to produce the DOM.

Standardization of the Shape of Ground Control Point (GCP) and the Methodology for Its Detection in Images for UAV-Based Mapping Applications

2019
The challenge of georeferencing aerial images for an accurate object to image correspondence has gained significance over the past couple of years. There is an ever-increasing need to establish accurate georeferencing techniques for Unmanned Aerial Vehicles (UAVs) for tasks like aerial surveyance of mines/construction sites, change detection along ...

Influences of the Ground Control Point (GCP) configuration on the UAV-derived Structure from Motion (SfM) in the coastal environment

Earth Science Informatics
In recent years, there has been a considerable increase in the use of Unmanned Aerial Vehicles (UAVs) for conducting high-resolution topographic surveys across various environments, with excellent outcomes. Photogrammetric surveys, in particular those employing drones, constitute the primary technique for reconstructing topography.

KAJIAN KETELITIAN TITIK GCP (GROUND CONTROL POINT) MENGGUNAKAN APLIKASI ONLINE POST-PROCESSING INA-CORS UNTUK ORTORHEKTIFIKASI CITRA SATELIT RESOLUSI TINGGI

Prosiding SEMSINA
Orthorektifikasi citra merupakan proses memposisikan kembali citra sesuai lokasi sebenarnya, dikarenakan pada saat pengambilan data terjadi pergeseran yang diakibatkan posisi miring pada satelit dan variasi topografi. Orthorektifikasi selain digunakan untuk mengkoreksikan citra secara geometrik, juga mengkoreksi citra berdasarkan ketinggian ...
