Different Faraday Rotation (FR) estimators are discussed, their estimation performances are assessed and compared to each other. The algorithms are applied on a set of quad-pol ALOS Pal-SAR data and the obtained estimates are validated against FR values derived from TEC maps obtained from GPS measurements.

Remote sensing data from multi-source optical and SAR (Synthetic Aperture Radar) sensors have been widely utilized to detect forest dynamics under a variety of conditions. Due to different temporal coverage, spatial resolution, and spectral characteristics, these sensors usually perform differently from one another. To conduct statistical modeling accuracies evaluation and comparison among seve...

Chronic disease management programs (CDMPs) were introduced in Australia to reduce unnecessary health care utilization by the growing population with chronic conditions; however, evidence of effectiveness is needed. This study evaluated the impact of a comprehensive CDMP, My Health Guardian (MHG), on rate of hospital admissions, readmissions, and average length of hospital stay (ALOS) for insur...

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), ...

The purpose of the proposed work is to examine the feasibility of using Polarimetric Interferometric SAR (PolInSAR) techniques on ALOS PALSAR data to extract forest canopy heights with the ultimate objective of deriving biomass estimates. Previous work [1] has shown that in homogeneous European forest stands, tree height is a reasonably robust estimator of biomass through a simple allometric re...

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...

One of the instruments on board of the ALOS satellite, launched by the Japanese Aerospace Exploration Agency (JAXA) in 2006, is the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM). PRISM has three cameras with different viewing directions (nadir, forward, backward), recording imagery with a ground resolution of 2.5 m. A main characteristic of raw ALOS PRISM imagery is that dep...

This paper discusses an initial polarimetric calibration of ALOS PALSAR. ALOS was launched on January 24, 2006. PALSAR, which is one of ALOS three sensors, is the first spaceborne L−band polarimetric synthetic aperture radar. It is expected that PALSAR polarimetric data is used for many applications such as agriculture, forestry, ocean, natural disasters etc. Thus, polarimetric calibration is a...

This paper aims to develop a new methodology for monitoring forest disturbances and regrowth using ALOS PALSAR data in tropical regions. In the study, forest disturbances and regrowth were assessed between 2007 and 2010 in Vietnam, Cambodia and Lao People’s Democratic Republic. The deforestation rate in Vietnam has been among the highest in the tropics in the last few decades, and those in Camb...

OBJECTIVES This study aimed to promote quality end-of-life (EOL) care for nursing home residents, through the establishment of advance care plan (ACP) and introduction of a new care pathway. This pathway bypassed the emergency room (ER) and acute medical wards by facilitating direct clinical admission to an extended-care facility. DESIGN An audit on a new clinical initiative that entailed the...
