The idea of assessing the damages to roads network after earthquake strikes has been referred as a matter of importance for performing every systematically planned activity in the affected region. When gathering information about the devastated region is crucially costly and time-consuming and in most cases impossible, high-resolution satellite imagery is hired to provide fast and accurate info...

Earth observation at regional scales, such as of the Iberian Peninsula or Mediterranean Basin, is an important tool to understand the relationships between climate and surface properties. Among the different layers of information that can be derived from satellite imagery, land cover maps are important by themselves and as an aid to infer other variables. Land cover legends at regional scales r...

The WWW is increasingly being used as a platform for the presentation of distance education courses. Such a medium has a number of important advantages, among them easy world-wide access to the courses, and ease and flexibility in updating course materials. The Australian Bureau of Meteorology’s Training Centre is participating in a European-based project known as EuroMET (the European Meteorol...

Urban change analysis has traditionally been supported through land use/cover classification and map-to-map comparison. In this research, we investigate the usefulness of satellitederived imperviousness index as an alternative for urban spatial growth characterization. The study area, Pensacola, FL, has witnessed considerable growth in population and regional economies during the past decade. T...

Recently, it has become much easier to obtain commercial high-resolution satellite imagery (HRSI), and application of IKONOS satellite imagery to 3D positioning has recently been investigated, with sub-meter accuracy being achieved. Image matching is one of the most fundamental processes in geopositioning from multi-image HRSI. Least squares matching and cross correlation matching are the most ...

[1] Rupture of the Sunda megathrust on 26 December 2004 produced broad regions of uplift and subsidence. We define the pivot line separating these regions as a first step in defining the lateral extent and the downdip limit of rupture during that great Mw 9.2 earthquake. In the region of the Andaman and Nicobar islands we rely exclusively on the interpretation of satellite imagery and a tidal m...

The feasibility to develop a rapid urban seismic damage detection procedure utilizing satellite radar imagery is investigated. In direct observation of city-wide building loss, remote sensing damage detection techniques have shown merits in rapid damage detection in urban areas. Remote sensing technology has the capability of extracting buildings in urban scenes. Comparing “before” and “after” ...

Actualization of cartographic data using imagery is an important application in the earth sciences. Extraction of map objects such roads from satellite imagery are an important task in many civilian and military applications. Particularly, extraction of these objects from digital imagery is of major practical importance for data acquisition and update of geographic information systems GIS datab...

Vegetation plays a key role in reducing ambient temperature, moisture and pollutant capture, energy use and subsequent ground level ozone reduction. In recent years vegetation mapping has become increasingly important, especially with advancements in environmental economic valuation. The spatial information from the remote sensing satellites enables researchers to quantify and qualify the amoun...

For a quick and stable estimation of earthquake damaged buildings worldwide, using Phased Array type L-band Synthetic Aperture Radar (PALSAR) loaded on the Advanced Land Observing Satellite (ALOS) satellite, a model combining the usage of satellite synthetic aperture radar (SAR) imagery and Japan Meteorological Agency (JMA)-scale seismic intensity is proposed. In order to expand the existing C-...
