The coal development zone of Northern Shaanxi, China is one of the eight largest coal mines in the world, also the national energy and chemical bases. However, the coal mining leads to ground surface deformation and previous studies show that in collapse fissure zone soil water losses almost 50% compared with non-fissure zone. The main objective of this study is to develop a retrieval model tha...

Digital image processing techniques were used for mapping structural features using a medium resolution image (ETM+) from Landsat 7. The aim of this study is to utilize remote sensed data and digital image processing techniques for updating the structural map in the north eastern part of the Dead Sea (Ma’in area), Jordan. The study area is becoming an important target for geological survey acti...

This study examines the need/importance for ground validation of Landsat 5 Thematic Mapper (TM) and 7 Enhanced Plus (ETM+) observation at 2 gas flaring sites in Rivers State Niger Delta, Nigeria. 12 imageries (3 TM 9 ETM+) acquired from 25/03/1987 to 08/03/2013 with < % cloud contamination were used. Both are located within a single scene (Path 188, Row 057). Fieldwork measurements obser...

Vegetation moisture and dry matter content are important indicators in predicting the behavior of fire and it is widely used in fire spread models. In this study, leaf fuel moisture content such as Live Fuel Moisture Content (LFMC), Leaf Relative Water Content (RWC), Dead Fuel Moisture Content (DFMC), and Leaf Dry Matter Content (LDMC) (hereinafter known as moisture content indices (MCI)) were ...

The concept of Economic Traffic Management (ETM) encompasses various techniques for optimizing overlay networks considering both, underlay and overlay networks’ performance requirements as well as the resulting economic implications for ISPs. This work presents several mechanisms through an overall ETM System (ETMS), identifying the possibility for synergies between mechanisms, both in the sens...

Interviewing stakeholders is a common way to elicit information about requirements of the system-to-be and the conditions in its operating environment. One difficulty in preparing and doing interviews is how to avoid missing the information that may be important to understand the requirements and environment conditions. Some information may remain implicit throughout the interview, if the inter...

An atmospheric correction tool has been developed for public web site access for the Landsat-5 and Landsat-7 thermal band. The Atmospheric Correction Parameter Calculator uses the National Centers for Environmental Prediction (NCEP) modeled atmospheric global profiles for a particular date, time and location as input. Using commercially-available MODTRAN software and a suite of integration algo...

The increasing number of sensor types for terrestrial remote sensing has necessitated supplementary efforts to evaluate and standardize data from the different available sensors. In this study, we assess the potential use of IKONOS, ETM+, and SPOT HRVIR sensors for leaf area index (LAI) estimation in forest stands. In situ measurements of LAI in 28 coniferous and deciduous stands are compared t...

-This is the second paper of the series on atmospheric correction of ETM+ land surface imagery. In the first paper, a new algorithm that corrects heterogeneous aerosol scattering and surface adjacency effects was presented. In this study, our objectives are to 1) evaluate the accuracy of this new atmospheric correction algorithm using ground radiometric measurements; 2) apply this algorithm to ...
