This study assessed landslide susceptibility in Shahpur valley, situated the eastern Hindu Kush. Here, landslides are recurrent phenomena that disrupt natural environment, and almost every year, they cause huge property damages human losses. These expected to escalate area due high rate of deforestation region, population growth, agricultural expansion, infrastructural development on slopes. La...

This paper presents a practical epipolarity model for high-resolution linear pushbroom satellite images acquired in either along-track or cross-track mode, based on the projection reference plane in object space. A new method for epipolar resampling of satellite stereo imagery based on this model is then developed. In this method, the pixel-to-pixel relationship between the original image and t...

In order to overcome the insufficiency of single remote sensing data source during information extraction, to make use of the complementary characteristics of SAR data and optical imagery, and to facilitate better monitoring and evaluation of resources and ecological environment, this paper develops the idea and presents the approach to land use/cover change detection by different temporal SAR ...

Digital terrain models (DTMs) were extracted from high-resolution stereo images (SPOT-5, EROS-A, IKONOS-II and QuickBird) using a three-dimensional universal physical model developed at the Canada Centre for Remote Sensing, Natural Resources Canada. DEMs were generated using an area-based multi-scale image matching method and then compared to 0.2-m accurate lidar elevation data. Elevation linea...

Over the past few decades, clearing for shrimp farming has caused severe losses of mangroves in the Mekong Delta (MD) of Vietnam. Although the increasing importance of shrimp aquaculture in Vietnam has brought significant financial benefits to the local communities, the rapid and largely uncontrolled increase in aquacultural area has contributed to a considerable loss of mangrove forests and to...

A multi-scale object-based classification was carried out using data from three different sensors to map classes of interest in the framework of the EPISTIS project. This project aims to highlight the spatio-temporal patterns that underlie the epidemiology of certain diseases and more particularly of bluetongue in this case-study. A SPOT5 10m XS image of Sardinia taken in the springtime was seg...

We investigate the elevation and mass-balance response of tributary glaciers following the loss of the Larsen A and B ice shelves, Antarctic Peninsula (in 1995 and 2002 respectively). Our study uses MODIS imagery to track ice extent, and ASTER and SPOT5 digital elevation models (DEMs) plus ATM and ICESat laser altimetry to track elevation changes, spanning the period 2001–09. The measured Larse...
