From the different contributions made during this symposium it becomes clear that, after a set of new sensors like Envisat, Ikonos, Quickbird, ASTER, MODIS ... became operational, now also the applications have reached the operational stage. The development of adapted methodologies to this new generation of sensors needs a couple of years before entering the application stage.
It is also clear that Very High Resolution data has entered definitively the remote sensing applications "forum", with the emphasis on studies dealing with resolutions adapted to new application areas, urban structures for example, something which was not possible in the past since the resolutions were not appropriate. Many contributions illustrate the use of sensors with a better and finer spectral resolution. Environmental protection, a new field of application was also the theme of several contributions.
It must be started, nevertheless, that for the moment radar images remain the inherent tool for certain applications and Landsat TM and ETM+ for optical remote sensing, remain the "work horses". The recent difficulties with the Landcast sensor, however, may change this part of the "remote sensing landscape". But other sensors with others and sometimes more possibilities are ready to take over. Wo=ith new strategies for Earth observation being formulated, one may conclude that the remote sensing community really is in transition.Note de contenu : - Keynote lectures

The system has been tested on 2.5m per pixel and 1m per pixel aerial images processed to have the characteristics of SPOT 5 and Ikonos output. A system using simple geometric models gives good results for bridges over roads and railroads, and very bad results for bridges over larger regions such as rivers. In contrast, a system using a texture-based classification and hand-made rules applied to that classification gives good results for bridges over rivers and railroads, and bad results for bridges over roads.

[Termes IGN] urbanisationRésumé : (Auteur) The potential of high resolution IKONOS and QuickBird satellite imagery for mapping and analysis of land and water resources at local scales in Minnesota is assessed in a series of three applications. The applications and accuracies evaluated include: (1) classification of lake water clarity (r 2 = 0.89), (2) mapping of urban impervious surface area (r2 = 0.98), and (3) aquatic vegetation surveys of emergent and submergent plant groups (80% accuracy). There were several notable findings from these applications. For example, modeling and estimation approaches developed for Landsat TM data for continuous variables such as lake water clarity and impervious surface area can be applied to high resolution satellite data. The rapid delivery of spatial data can be coupled with current GPS and field computer technologies to bring the imagery into the field for cover type validation. We also found several limitations in working with this data type. For example, shadows can influence feature classification and their effects need to be evaluated. Nevertheless, high resolution satellite data has excellent potential to extend satellite remote sensing beyond what has been possible with aerial photography and Landsat data, and should be of interest to resource managers as a way to create timely and reliable assessments of land and water resources at a local scale.

[Termes IGN] réflectanceRésumé : (Auteur) This study uses IKONOS imagery to quantify the combined spatial and spectral charactenistics of urban reflectance in 14 urban areas worldwide. IKONOS 1-m panchromatic imagery provides a detailed measure of spatial variations in albedo while IKONOS 4-m multispectral imagery allows the relative contributions of different matenials to the spectrally heterogeneous radiance field to be determined and their abundance to be mapped. Spatial autocorrelation analyses indicate that the characteristic scale of urban reflectance is consistently between 10 and 20 m for the cities in this study. Spectral mixture analysis quantifies the relative contributions of the dominant spectral endmembers to the overall reflectance of the urban mosaic. Spectral mixing spaces defined by the two low-order principal components account for 96% to 990% of image variance and have a consistent triangular structure spanned by high albedo, low albedo and vegetation endmembers. Spectral mixing among these endmembers is predominantly linear although some nonlinear mixing is observed along the gray axis spanning the high and low albedo endmembers. Inversion of a constrained three-component linear mixing model produces stable, consistent estimates of endmember abundance. RMS errors based on the misfit between observed radiance vectors and modeled radiance vectors (derived from fraction estimates and image endmembers) are generally less than 3% of the mean of the observed radiance. Agreement between observed radiance and fraction estimates does not guarantee the accuracy of the areal fraction estimates, but it does indicate that the three-component linear model provides a consistent and widely applicable physical characterization of urban reflectance. Field validated fraction estimates have applications in urban vegetation monitoring and pervious surface mapping.
