[Termes IGN] test de performanceRésumé : (Auteur) The spatial resolution attributed to digital cameras is usually based on the number or size of the pixels in the sensor. On closer examination it can often be shown that the real limit to the level of detail recorded by a camera will in practice be due to the performance of the optical system. An example of how this happens is given with a comparison between two satellite camera systems.

[Termes IGN] traitement de données GNSSRésumé : (Auteur) Starting in 2001 the EUREF Permanent Network (EPN) Local Analysis Centres (LAC) are delivering Zenith Total Delay (ZTD) parameters which were combined at the BKG (Bundesamt für Kartographie und Geodäsie, Germany) combination facility. The results have been step-by-step improved, depending on several changes of the processing scheme, leading to an internal precision of 2-3 mm ZTD. The availability of a set of homogeneously processed GPS satellite orbits, clocks and Earth Rotation Parameters (ERP) covering a period of more than a decade (the so-called Potsdam-Dresden reprocessing) motivated MUT (Military University of Technology, Poland) to the all-in-one processing of the EPN stations for the same period. The applied strategy thereby followed the guidelines for EPN processing. While the improvement in coordinate estimation has been recently demonstrated, this paper investigates the quality of the ZTD parameters estimated together with the coordinates. Comparisons with the existing EUREF combined solution, with IGS solutions and with radiosonde data will be presented to evaluate the possible improvement in ZTD estimation by reprocessing activities.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Airborne has yet to become as ubiquitous as aerial imagery for GIS application. But one important use has recently been identified. An online atlas of potential solar energy yield was created for the city of Berlin by measuring parameters such as roof area and slop, taking into account shadowing from vertical objects such as chimneys and masts. The atlas is freely accessible to home and business owners and the hope is that will create more demand for photovoltaic and solar thermal panels.

[Termes IGN] traitement de données GNSSRésumé : (Auteur) Real-time corrections at the decimeter level over an entire continent? The challenge lies in minimizing the ranging errors from signals propagating through the Earth’s atmosphere. European researchers describe how it can be done using a Wide Area Real-Time Kinematic concept that exploits the full geometry of the observations, a central processing facility, and undifferenced processing of measurements from widely space GNSS reference receivers to create a real-time ionospheric model of the signal slant delays.

[Termes IGN] polarimétrie radarRésumé : (Auteur) This paper assesses the potential of using spaceborne X-band synthetic aperture radar (SAR) data for monitoring water-level changes over wetlands. Our analysis is based on three sets of TerraSAR-X (TSX) observations acquired over South Florida's Everglades wetlands during an eight-month period in 2008. The first set was acquired in single HH polarization stripmap mode over our northern study area, consisting of managed wetlands and urban environments. The second set was acquired in dual-polarization stripmap mode over the western half of the same area, consisting mostly of managed wetlands. The third set was also acquired with dual-polarization stripmap mode over our southern study area, consisting of natural flow freshand salt-water wetlands in the southern Everglades. The first data set was used for a proof-of-concept study to verify that X-band data can generate coherent interferograms in wetland areas. Interferometric processing of this data set shows a high level of coherence (> 0.35) over both wetland and urban regions, maintaining interferometric phase in all three interferograms spanning 11 days. Surprisingly, phase is maintained over some of the wetlands even for interferograms spanning 33 days. The other two data sets were used to evaluate interferometric coherence of all four polarization modes and to determine dominant scattering mechanism in each wetland environment. Our results show high coherence values (> 0.4) in all polarization modes, with highest values in HH, then VV, and lowest in HV or VH. Interferograms calculated from multipolarization data show very similar fringe patterns regardless of the polarization type, suggesting that the phase information in all polarization data reflects water-level changes in wetlands and that volume scattering may be less important than commonly believed. We also used the two multipolarization data sets to conduct the Pauli decomposition, finding a strong dependence of scattering mechanism on vegetation type. The high interferometric coherence level of all polarization data suggests that a significant part of the X-band scattered signal interacts with lower sections of the vegetation (trunks and branches), because scattering from wind-affected canopies cannot support such a high coherence level. The high spatial resolution of TSX, combined with its 11-day repeat orbit, makes this X-band sensor surprisingly suitable for wetland interferometric SAR applications.
