In particular, we investigate the application of the Kriging geostatistical technique to obtain regularly spaced IPWV values. The horizontal spatial structure r water vapor retrieved by SSM/I is explored by computing-variograms that provide a measure of dissimilarity between pairs IPWV values for the region of interest. Because the water vapor density decreases with height, the GPS station elevation - accounted for in the interpolation procedure. In this respect, the potential of the Kriging with external drift relative to the linary Kriging is evaluated by applying a test based on the validation approach.The case studies are presented and qualitatively compared to the corresponding Meteosat infrared images. A quantitative comparison with an independent source of information, such as IPWV computed from radiosonde observations and from European Centre for Medium-Range Weather Forecasts only, is also performed.

[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) Yesterday's revolution is today's status quo. A few years ago, laser scanning was a novelty in mine survey. Mines without laser surveying are now operating at a disadvantage. Soon they will be anachronisms. In 1400 BC, the Egyptians first used surveying to accurately divide land into plots for taxation purposes. At the same time, polished surfaces were being used as reflectors to send messages. Three thousand years on, advances in the field of optics paved the way for many technological leaps, not the least being telescopes and instruments for more precise measurements. During the industrial revolution, the importance of exact boundaries for public utilities brought surveying into prominence. More accurate instruments were developed. Demand increased. Surveying now impacts all aspects of modern life.

[Termes IGN] système de coordonnéesRésumé : (Auteur) As a model for sensor orientation and 3D geopositioning for high-resolution satellite imagery (HRSI), the affine transformation from object to image space has obvious advantages. Chief among these is that it is a straightforward linear model, comprising only eight parameters, which has been shown to yield sub-pixel geopositioning accuracy when applied to Ikonos stereo imagery. This paper aims to provide further insight into the affine model in order to understand why it performs as well as it does. Initially, the model is compared to counterpart, 'rigorous' affine transformation formulations which account for the conversion from a central perspective to affine image. Examination of these rigorous models sheds light on issues such as the effects of terrain and size of area, as well as upon the choice of reference coordinate system and the impact of the adopted scanning mode of the sensor. The results of application of the affine sensor orientation model to four multi-image Ikonos test field configurations are then presented. These illustrate the very high geopositioning accuracy attainable with the affine model, and illustrate that the model is not affected by size of area, but can be influenced to a modest extent by mountainous terrain, the mode of scanning and the choice of object space coordinate system. Above all, the affine model is shown to be both a robust and practical sensor orientation/triangulation model with high metric potential.

[Termes IGN] traitement d'imageRésumé : (Auteur) Timely and accurate change detection of Earth's surface features is extremely important for understanding relationships and interactions between human and natural phenomena in order to promote better decision making. Remote sensing data are primary sources extensively used for change detection in recent decades. Many change detection techniques have been developed. This paper summarizes and reviews these techniques. Previous literature has shown that image differencing, principal component analysis and post-classification comparison are the most common methods used for change detection. In recent years, spectral mixture analysis, artificial neural networks and integration of geographical information system and remote sensing data have become important techniques for change detection applications. Different change detection algorithms have their own merits and no single approach is optimal and applicable to all cases. In practice, different algorithms are often compared to find the best change detection results for a specific application. Research of change detection techniques is still an active topic and new techniques are needed to effectively use the increasingly diverse and complex remotely sensed data available or projected to be soon available from satellite and airborne sensors. This paper is a comprehensive exploration of all the major change detection approaches implemented as found in the literature.
