It has, however, over recent years established a fundamental role in monitoring and describing changes to the Earth’s surface. In particular, this article describes the state of the art of the GPS contribution to Seismology, and presents an innovative methodology, VADASE, that enables accurate estimation of co-seismic displacement waveforms in real time using standard broadcast products and high-rate carrier-phase observations collected by a unique GPS receiver. This represents a potential enhancement to GPS Seismology and an effective support for tsunami early warning systems.

Accuracy assessment of high resolution satellite imagery orientation by leave-one-out method / Maria Antonia Brovelli in ISPRS Journal of photogrammetry and remote sensing, vol 63 n° 4 (July - August 2008)

Fundamental and critical goals for the geometric use of this kind of imagery are their orientation and orthorectification, processes able to georeference the imagery and correct the geometric deformations they undergo during acquisition. In order to exploit the actual potentialities of orthorectified imagery in Geomatics applications, the definition of a methodology to assess the spatial accuracy achievable from oriented imagery is a crucial topic. In this paper we want to propose a new method for accuracy assessment based on the Leave-One-Out Cross-Validation (LOOCV), a model validation method already applied in different fields such as machine learning, bioinformatics and generally in any other field requiring an evaluation of the performance of a learning algorithm (e.g. in geostatistics), but never applied to HRSI orientation accuracy assessment. The proposed method exhibits interesting features which are able to overcome the most remarkable drawbacks involved by the commonly used method (Hold-Out Validation — HOV), based on the partitioning of the known ground points in two sets: the first is used in the orientation–orthorectification model (GCPs — Ground Control Points) and the second is used to validate the model itself (CPs — Check Points). In fact the HOV is generally not reliable and it is not applicable when a low number of ground points is available. To test the proposed method we implemented a new routine that performs the LOOCV in the software SISAR, developed by the Geodesy and Geomatics Team at the Sapienza University of Rome to perform the rigorous orientation of HRSI; this routine was tested on some EROS-A and QuickBird images. Moreover, these images were also oriented using the world recognized commercial software OrthoEngine v. 10 (included in the Geomatica suite by PCI), manually performing the LOOCV since only the HOV is implemented. The software comparison guaranteed about the overall correctness and good performances of the SISAR model, whereas the results showed the good features of the LOOCV method.

In this paper, we focus on the georeferencing of pushbroom sensors with rigorous models, that is, approaches that are based on the photogrammetric collinearity equations and describe the exact acquisition geometry of the sensors. By solving a bundle adjustment, the sensor external orientation and additional geometric parameters describing the internal orientation are estimated. We tested two rigorous models developed in academic groups for the georeferencing of a stereopair from QuickBird. The first model (M1) has been implemented at the University La Sapienza, Rome. It is specifically designed for the orthorectification of pushbroom sensors carried on satellite platforms with asynchronous acquisition mode, like EROS-A and QuickBird. The model, implemented in the software SISAR, reconstructs of the orbital segment during the image acquisition through the knowledge of Keplerian orbital parameters, the sensor attitude, internal orientation and the self-calibration parameters. The second model (M2) is a rigorous sensor model for pushbroom linear array sensors, carried on airborne or spaceborne platforms. It estimates the parameters modelling the sensor internal and external orientation through a bundle adjustment, using a suitable number of ground control points. Our research included the orientation of the single images with rigorous model M1, the orientation of the stereo pair with rigorous model M2 and the comparison of the results with a rigorous model contained in commercial software (PCI OrthoEngine). The results demonstrate that by using rigorous models it is possible to achieve RMSE smaller than 1 pixel in the GPs if a sufficient number of GCPs are used.
