any human activities affect or are affected by physical and chemical processes occurring in the Earth’s atmosphere, ionosphere, and near-Earth space environment. In this article, we review a wide range of remote sensing research activities being carried out within the APL Space Department that have provided a better understanding of these processes. The research, conducted from both the ground ...
Earthquakes are among the most catastrophic natural disasters to affect mankind. One of the critical problems after an earthquake is building damage assessment. The area, amount, rate, and type of the damage are essential information for rescue, humanitarian and reconstruction operations in the disaster area. Remote sensing techniques play an important role in obtaining building damage informat...
A review of recent developments related to soil hydraulic property estimation using remote sensing is presented. Several soil hydraulic parameter estimation techniques using proximal-, air-, or satellite-based remotely sensed soil moisture, land surface temperature, and/ or evapotranspiration time series have evolved over the past decades. In particular, microwave remote sensing of near-surface...
Remote sensing indices are used to analyze the Spatio-temporal distribution of drought conditions and to identify the severity of drought. This study, using various drought indices generated from Madis and TRMM satellite data extracted from Google Earth Engine (GEE) platform. Drought conditions in Marivan city from February to November for the years 2001 to 2017 were analyzed based on spatial a...
Avian species persistence in a forest patch is strongly related to the degree of isolation and size of a forest patch and the vegetation structure within a patch and its matrix are important predictors of bird habitat suitability. A combination of space-borne optical (Landsat), ALOS-PALSAR (radar), and airborne Light Detection and Ranging (LiDAR) data was used for assessing variation in forest ...
“Fundamentals of Satellite Remote Sensing: An Environmental Approach” by Emilio Chuvieco introduces remote sensing data as a valuable source of information in understanding our environment. The second edition of this book aims to describe sources of available remote sensing data and how this data can be exploited as a key piece of information in environmental applications. Chuvieco focuses on p...
Analyzing the Spatial Pattern of Drought in Central and South Zagros Using Remote Sensing Indicators
Introduction: As a complex phenomenon occurring due to a long period of poor precipitation, drought causes water scarcity in the soil and the hydrological system via hydrological, bringing about long-term consequences which may lead to severe economic, environmental, and social problems worldwide. Droughts are classified into four types: meteorological (rainfall), agricultural (soil’s moisture)...
Reflectance spectrometry techniques with the integration of remote sensing data help us in identifying and mapping the phenomena on the earth. Using these techniques to discriminate the petrologic units independently and without knowing the spectral behavior of rocks along the electromagnetic wavelengths can not be so much useful. For the purposes of this study, 65 samples of igneous and metamo...
