“…In the commissioning phase, the images were evaluated by their radiometric and geometric characteristics. [4] carried out the radiometric calibration and the image quality assessment with respect to signal-to-noise ratio, modulation transfer function and general image quality equation. [5] handled both horizontal and vertical accuracy of various products levels (L3A, L3B, L4A, L4B) covering ve test sites in Türkiye.…”

The panchromatic tri-stereo images of Göktürk-1, the first sub-meter optical remote sensing satellite of Türkiye, was assessed with respect to 3D georeferencing accuracy using sensor-dependent orientation model. The investigated panchromatic images were acquired in tri-stereo mode with 50 cm ground sampling distance at nadir-view, covering Zonguldak (Türkiye) test site. The sensor-dependent orientation model developed for the Pléiades 1A/1B/Neo and SPOT 6/7 satellites were preferred since the characteristics of Göktürk-1’s imaging geometry was identical with them. Two GCP/ICP sets (50/9 and 44/15) were established by in-field GNSS survey, and adjusted georeferencing accuracy were estimated almost millimetre and ~ ± 50 cm ( ~ ± 1 GSD) at GCPs and ICPs, respectively. All process was carried out by Geo3o1 tool of GeoEtrim derived in MATLAB environment.

The general image quality equation (GIQE) maps imaging system parameters to performance in terms of common detection and recognition tasks. Changes to the National Imagery Interpretation Rating Scale led to the development of GIQE version 5 in 2015. The purpose of this paper is to provide a review of GIQE 5 applications in the literature, a tutorial on its use, and, for the first time , an independent validation of the new model along with comparisons to GIQEs 3 and 4.
