Apport des images satellitaires très haute résolution sur une étude de tracé d'infrastructure routière

open access: yesRevue Française de Photogrammétrie et de Télédétection, 2015
La quatrième rocade d'Alger a fait l'objet d'une étude préliminaire de faisabilité géotechnique en 2009 à partir d'images SPOT5 Ortho Basic. Adoptant une démarche naturaliste, une étude comparative est menée entre ces images et les images PLEIADES XS et ...

RESEARCH OF THE LONG-TERM BEHAVIOUR OF THE PLEIADES BY USING OF PHOTOGRAPHIC PLATES FROM UKRVO DIGITAL ARCHIVE AND BALDONE OBSERVATORY

open access: yesOdessa Astronomical Publications, 2016
The Pleiades Star Cluster (M45) is one of the most studied star clusters in the galaxy. At the same time as part of the Pleiades are many long-period variable stars, including flashing that need further study.

Vegetation Height Estimation Near Power transmission poles Via satellite Stereo Images using 3D Depth Estimation Algorithms [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Monitoring vegetation encroachment under overhead high voltage power line is a challenging problem for electricity distribution companies. Absence of proper monitoring could result in damage to the power lines and consequently cause blackout.

3D CAPABILITIES OF PLEIADES SATELLITE [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
End of 2011 a new optical satellite, called Pléiades, was launched by the French space agency (CNES). It provides 20 km x 20 km images at 0.5 meters. This agile acquisition system is able to relocate very rapidly and scan the earth in any direction. The

Potential of Pléiades and WorldView-3 Tri-Stereo DSMs to Represent Heights of Small Isolated Objects

open access: yesItalian National Conference on Sensors, 2020
High-resolution stereo and multi-view imagery are used for digital surface model (DSM) derivation over large areas for numerous applications in topography, cartography, geomorphology, and 3D surface modelling.

Radiometric and geometric characteristics of Pleiades images [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Pleiades images are distributed with 50 cm ground sampling distance (GSD) even if the physical resolution for nadir images is just 70 cm. By theory this should influence the effective GSD determined by means of point spread function at image edges ...

ROTATION IN THE PLEIADES WITH K2. I. DATA AND FIRST RESULTS [PDF]

open access: yes, 2016
Young (125 Myr), populous (>1000 members), and relatively nearby, the Pleiades has provided an anchor for stellar angular momentum models for both younger and older stars. We used K2 to explore the distribution of rotation periods in the Pleiades.

Simultaneous Kepler/K2 and XMM‐Newton observations of superflares in the Pleiades [PDF]

open access: yesAstronomical Notes - Astronomische Nachrichten, 2019
Context. Flares are powerful events ignited by a sudden release of magnetic energy which triggers a cascade of interconnected phenomena, each resulting in emission in different electromagnetic bands.
