“…This prestudy gives evidence that the use of videos with higher radiometric and spatial resolution will extend the capabilities of existing unmanned orbital sensor systems (e.g. Poli & Toutin, 2012;Rupnik, Pierrot Deseilligny, Delorme, & Klinger, 2016). Especially SkySat (d 'Angelo, Máttyus, & Reinartz, 2015) has already shown that sub-meter resolution imagery and high-definition video are valuable for Earth observation.…”

A large variety of various passive and active satellite sensors producing panchromatic, multispectral or hyperspectral images of the Earth's surface are currently in space and are used in different scientific fields such as earth science (e.g. geography, hydrology, geology, oceanography and glaciology), disaster management, as well as for military, commercial and economic purposes. In contrast, video files are a rather exotic data format in the field of Earth observation. Occasionally, video cameras are used in airborne remote sensing, but only recently video Earth observation from space has been established. This paper aims at the integration of video data in the scientific workflow, revealing advantages and disadvantages of moving images. Being the only available source for continuous video Earth observation data, the NASA experiment High Definition Earth Viewing on-board the International Space Station is the basis for our evaluation of the usability of video data. Following the rather coarse resolution of these data, we exemplify some potential fields of application in science and education. We show a basic workflow how to produce 3D models and stereoscopic videos of the Earth's surface. As a pre-study for videos with better spatial as well as radiometric resolution, the delivered products serve not only scientific purposes, but are integrated in school lessons to evoke the pupils' fascination for earth sciences and space.

Observations of surface deformation within 1–2 km of a surface rupture contain invaluable information about the coseismic behavior of the shallow crust. We investigate the oblique strike‐slip 2016 M7 Kumamoto, Japan, earthquake, which ruptured the Futagawa‐Hinagu Fault. We solve for variable fault slip in an inversion of differential lidar topography, satellite optical image correlation, and Interferometric Synthetic Aperture Radar (InSAR)‐derived surface displacements. The near‐fault differential lidar pose several challenges. The model fault geometry must follow the surface trace at the sub‐kilometer scale. Integration of displacement datasets with different sensitivities to the 3D deformation field and varying spatial distribution permits additional complexity in the inferred slip but introduces ambiguity that requires careful selection of the regularization. We infer a Mw 7.09−0.05+0.03 earthquake. The maximum slip of 6.9 m occurred at 4.5‐km depth, suggesting an on‐fault slip deficit in the upper several kilometers of the crust that likely reflects distributed and inelastic deformation within the shallow fault zone.

“…The orientation results obtained with RPC are usually refined introducing a 6-parameter 1st-order transformation in the RPF equation: (2) where the six parameters (A0, A1, A2, B0, B1, and B2) are estimated using a set of few GCPs [18][19][20][21].…”

High-resolution satellite images must undergo a geometric rectification process in order to be used for metrical purposes. This operation, called orthorectification, is necessary because of deformations mainly due to camera distortions and acquisition geometry. To correctly orthorectify an image, it is necessary to accurately reconstruct the photogrammetric-acquisition characteristics and the image position with respect to a reference system connected to the ground. This operation, called orientation, can be done using various mathematical models such as rigorous, rational polynomial function (RPF), and rational polynomial coefficient, or, according to some authors, rapid positioning coefficient (RPC) models. Orientation and orthorectification are usually performed within specific commercial software, but in QGIS, these complex operations can be performed using the open libraries of the Orfeo Tool Box (OTB). Unfortunately, instructions given by OTB developers lead to scarce results. In fact, the procedure proposed in OTB does not allow for the full exploitation of the potential of RPC models, on which OTB itself is based. As OTB is open-source software, a plugin was developed to overcome these limitations and exploit its full potential. In fact, OTB interfaces are unfortunately essential, and some necessary functions are missing. Therefore, a new QGIS plugin was developed in order to run the entire process in the most photogrammetrically and statistically correct way, and, at the same time, to simplify the relative procedures.
