Advanced land observation satellite (ALOS). 5 Outline of ALOS satellite system.

A Semi Automatic Road Extraction Method for Alos Satellite Imagery

A semi automatic road extraction method has been constructed and evaluated. Our purpose is to obtain 1/25,000 level road data from PRISM image. PRISM is panchromatic, three views, and the 2.5m resolution sensor carried on ALOS satellite that will be launched on late 2004. A centre line-detecting algorithm is employed for feature extraction. It picks up pixels where second derivative of brightne...

Ionospheric disturbances observed by the PALSAR onboard ALOS satellite

Crustal Deformation in Australia Measured by Satellite Radar Interferometry Using ALOS/PALSAR Imagery

The Advanced Land Observing Satellite (ALOS), launched on 24 January 2006, is a Japanese satellite carrying an L-band SAR sensor, namely the PALSAR, which is expected to demonstrate good performance in applications such as crustal deformation measurement, subsidence detection and landslide monitoring. This paper describes a case study of Differential Synthetic Aperture Radar Interferometry (DIn...

Damage detection in the 2015 Nepal earthquake using ALOS-2 satellite SAR imagery

The Mw 7.8 earthquake jolted the central region of Nepal on April 25, 2015, and caused gigantic destruction. Satellite remote sensing is an effective tool to grasp damages in a wide area. In this study, preand post-event ALOS-2 satellite SAR data were used to detect affected areas in Kathmandu, the capital city of Nepal. Firstly, the crustal movements around the Kathmandu Valley were estimated ...

A Generic Pushbroom Sensor Model for High-resolution Satellite Imagery Applied to Spot 5, Quickbird and Alos Data Sets

A new generic pushbroom sensor model for high-resolution satellite images is presented. The sensor orbit and attitudes are modelled by splines. In order to determine the parameters of the orbit and attitude splines, direct observations for the satellite orbits and attitudes that are provided by the data vendors in metadata files are considered. As these direct observations are usually contamina...
