Assessment of Alos Prism Digital Elevation Model Extraction over Japan
نویسندگان
چکیده
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 Model extraction. By analyzing ALOS data available over an area in Japan, with other reference information, this article will present both the current possibilities available with PRISM data and their limitations.

Generation of the 30 M-mesh Global Digital Surface Model by Alos Prism
Topographical information is fundamental to many geo-spatial related information and applications on Earth. Remote sensing satellites have the advantage in such fields because they are capable of global observation and repeatedly. Several satellite-based digital elevation datasets were provided to examine global terrains with medium resolutions e.g. the Shuttle Radar Topography Mission (SRTM), ...
