Pre-signals -changes in area measured by triangular networks of GPS receivers- were examined for many large earthquakes in Japan and in other Asian regions. We discovered that although the occurrence of location of an earthquake can be predicted, more research is required before the time of an earthquake can be precisely forecast.

[Termes IGN] JaponRésumé : (auteur) Castanopsis sieboldii var. sieboldii is an evergreen broadleaved canopy tree that grows on Honshu, Shikoku and Kyushu Islands in Japan. A closely-related, hybridizing, congener species, C. cuspidata var. cuspidata, has different leaf epidermis structure and different seed nuts morphology compared to C. sieboldii var. sieboldii. Furthermore, the habitats in which the two species grow often indicate different water requirements. Analysis of genetic diversity, using transcribed sequences, will provide a sound basis for the management of this species, allowing successful reforestation, incorporating phylogeographic conservation. In order to obtain transcripts sequences for the species and to develop transcript-based markers, we constructed and analyzed a cDNA library, surveyed microsatellite sequences within it and designed PCR primers for the microsatellites. The cDNA library was constructed using tissue from the inner bark of C. sieboldii var. sieboldii; 3354 Expressed Sequence Tags (ESTs) were identified. We constructed 2417 putative unigenes and assigned putative functions to 1856 of them. Three hundred and fourteen microsatellites were found within the putative unigenes and 16 EST-SSR (Simple Sequence Repeat) markers were developed. The EST-SSR markers developpe in this study should facilitate future analysis of the genetic diversity of this and related species.

[Termes IGN] turbidité des eauxRésumé : (Auteur) The remote sensing of Case 2 water has been far less successful than that of Case 1 water, due mainly to the complex interactions among optically active substances (e.g., phytoplankton, suspended sediments, colored dissolved organic matter, and water) in the former. To address this problem, we developed a spectral decomposition algorithm (SDA), based on a spectral linear mixture modeling approach. Through a tank experiment, we found that the SDA-based models were superior to conventional empirical models (e.g. using single band, band ratio, or arithmetic calculation of band) for accurate estimates of water quality parameters. In this paper, we develop a method for applying the SDA to Landsat-5 TM data on Lake Kasumigaura, a eutrophic lake in Japan characterized by high concentrations of suspended sediment, for mapping chlorophyll-a (Chl-a) and non-phytoplankton suspended sediment (NPSS) distributions. The results show that the SDA-based estimation model can be obtained by a tank experiment. Moreover, by combining this estimation model with satellite-SRSs (standard reflectance spectra : i.e., spectral endmembers) derived from biooptical modeling, we can directly apply the model to a satellite image. The same SDA-based estimation model for Chl-a concentration was applied to two Landsat-5 TM images, one acquired in April 1994 and the other in February 2006. The average Chl-a estimation error between the two was 9.9%, a result that indicates the potential robustness of the SDA-based estimation model. The average estimation error of NPSS concentration from the 2006 Landsat-5 TM image was 15.9%. The key point for successfully applying the SDA-based estimation model to satellite data is the method used to obtain a suitable satellite-SRS for each end-member.

[Termes IGN] photo-interprétation assistée par ordinateurRésumé : (Auteur) ALOS (Advanced Land Observing Satellite) was launched in January 2006, and this made it possible for the Geographical Survey Institute (GSI) to acquire high-resolution images (2,5 m) from the satellite's sensor PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping). It is expected that PRISM will be applied to the mapping and revision of 1:25 000-scale topographic maps. In collaboration with the Japan Aerospace Exploration Agency (JAXA), GSI has finished verifying and demonstrating the feasability of PRISM images for mapping and revision of 1:25 000-scale topographic maps, and has started using the images in its mapping program. This report describes this feasability study and details the actual applications of PRISM images for topographic mapping.

[Termes IGN] valeur radiométriqueRésumé : (Auteur) Elimination of displacement due to map editing inherent in road centerline data of the New Topographic map Information System (NTIS) is implemented. Panchromatic satellite images from ALOS/PRISM are used in the process. Histogram analysis of gray value profiles parallel to the roads is employed. The true-position candidate is selected by supervised classification of histograms using support vector machine (SVM) method. According to the experiments with the Japanese NTIS road centerline database, the proposed method reverses the displacement of approximately 50 % of the road features, while a further 20% of the road features are validated as already located at the true position. The proposed method is proved to be useful for German Amtliches Topographisch-Kartographisches InformationsSystem (ATKIS) road database. This indicates wider applicability of this method to various geographic regions.
