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...
The focus of this study was to thoroughly exploit the capability of very high-resolution VHR satellite imagery such as Ikonos and QuickBird for disaster mitigation. An efficient automated methodology that detects damage was implemented to derive the rich information available from VHR satellite imagery. Consequently, the detected results and the VHR satellite imagery are attractively presented ...
Complex event processing is an important technology with possible application in supply chain management and business activity monitoring. Its basis is the identification of event patterns within multiple occurring events having logical, causal or temporal relationships. The Rete algorithm is commonly used in rule-based systems to trigger certain actions if a corresponding rule holds. The algor...
On the 26th December 2003 an earthquake with MW=6.5 shook a large area of the Kerman Province in Iran. The epicenter of the devastating earthquake was located near the city of Bam. This paper described the application of differential synthetic aperture radar interferometry (D-INSAR) and ENVISAT ASAR data to map the coseismic surface deformation caused by the Bam earthquake including the interfe...
Remote sensing has proved its usefulness for the crisis mitigation through situation report and damage assessment. Visual analysis of satellite images is conducted by analysts, however automatic or decision aid method are desired. We propose a semi-automatic damage assessment method based on a pair of very high spatial resolution (VHR) images and some ancillary data. It is applied to two disast...
A large literature has focused on labour market institutions as a reason for slow growth in Europe. How important have product market regulations been? Recent work has shown that less regulation encourages investment, increases employment and leads to faster productivity growth. Empirical work at the firm level, within individual countries, suggests that the impact may differ in important ways ...

This paper presents a methodology for quantifying the number of buildings that collapsed following the Bam earthquake. The approach is ‘object’ rather than ‘pixel’-oriented, commencing with the inventory of buildings as objects within high-resolution Quickbird satellite imagery captured before the event. The number of collapsed structures is computed based on the unique statistical characterist...
Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...
In resent years, remote sensing technologies are utilized in disaster management as a means of information gathering in a large scale disaster. QuickBird captured a clear image of Bam City, eight days after the 2003 Bam, Iran, earthquake. The city was also observed by QuickBird about three months before the event. In this paper, we perform building damage detection based on land cover classific...
