This article presents technical work done with DAICHI ALOS PRISM data in order to assess the feasibility and quality of Digital Elevation Model extracted from ALOS PRISM triplet of images. Thanks to its configuration, the PRISM instrument is capable of simultaneous stereoscopic acquisition of the observed landscape which should easier the automatic processing of such data for Digital Elevation ...

This paper describes the research plan to use ALOS / PALSAR data for Antarctic ice sheet analysis. The final goal of our study is to extract the precise ice sheet elevation and estimate accurate position of grounding line using ALOS / PALSAR data. The authors have been studying the grounding line and ice sheet topography from InSAR data, which mainly used ERS-1/2 tandem data. We plan to adopt t...

Phenological or plant age classification across a landscape allows for examination of micro-topographical effects on plant growth, improvement in the accuracy of species discrimination, and will improve our understanding of the spatial variation in plant growth. In this paper six vegetation indices used in phenological studies (including the newly proposed PhIX index) were analysed for their ab...

OBJECTIVE To assess whether visual impairment contributes to average length of stay (ALOS) within inpatient care facilities. METHODS We used the New York State Department of Health's Statewide Planning and Research Cooperative System (SPARCS) data for 1993, containing 1 principal diagnosis code and up to 8 secondary diagnosis codes for approximately 2.6 million hospital discharges. We evaluat...

The new Japanese optical sensor ALOS/PRISM which was launched in January 2006 has stereo capabilities which can be used for a great number of applications and products. One of the most important products is the generation of Digital Surface Models (DSMs). With SAT-PP (Satellite Image Precision Processing) our group has developed a suite of new methods and a software package which can be used fo...

The aim of this study is to extract water body using the integrated features of Landsat ETM+ and ALOS PALSAR data. Water body extracted from Landsat ETM+ tends to lose smaller water bodies like small rivers and ponds. Besides, water area with plant (lotus) is difficult to recognize. ALOS PALSAR data have a much higher resolution, capable of extracting almost all the water bodies without confusi...

Retrievals of inherent optical properties (IOPs) and chlorophyll-a concentration (Chla) were investigated for AVNIR-2 images with 30 m spatial resolution and four bands in the southwest tropical lagoon of New Caledonia. We corrected the atmospheric and sea-surface reflectance iteratively through the retrieval of IOPs. After an additional correction of seafloor reflectance, the estimated IOPs an...
