The tests in Rome (Italy) were handled by [7] for estimating height accuracy, by [8] for orthoimage generation and validation, and by [9] regarding the classi cation for land use/cover. The pansharpening quality was analysed by [10] in Ankara (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 quite recent availability of satellite stereo pairs allows users to extract three-dimensional data that can be used in different domain of applications, such as urban planning, energy, emergency management, etc. This research paper aims to extract digital surface models (DSM) from satellite stereo pairs acquired by three different satellites (Deimos-2, Pléiades-1 and WorldView-3) over the area of the city of Turin (Italy). The results are then assessed in term of geometric accuracy comparing them with a cadastral point height dataset, used as benchmark. The comparison, in terms of difference height values (between the DSM and the benchmark), is calculated on a set of sample points. Just two of the generated DSM guaranteed a high height accuracy level useful for the domain of application, such as existing cartography update, emergency management, building damage assessment, roof slope and solar incoming radiation assessment. Further developments will investigate different blending techniques and software that could provide more accurate results.
