Remote Sensing of Environment

Remote sensing technique has emerged as an effective tool for systematic survey, analysis, and better management of natural resources (land, soil, water, forests, mountains) along with the monitoring of desertification, flood, drought, and landform change. It provides a vast scope to explore, identify, and analyze the natural resources of undeveloped regions. It documents the dynamic changes in physical processes and resulting landforms, usually by satellite images.

Remote sensing is defined according to certain functions. It involves acquiring the information of an object’s property by a device not in contact with that object under study. This involves the utilization at a distance of any device for gathering information pertinent to the environment, such as measurements of force fields, electromagnetic radiation, or acoustic energy for aircraft, spacecrafts, or ships. The technique employs such devices as a cameras, lasers, radio frequency receivers, radar systems, sonars, seismographs, gravimeters, magnetometers, and scintillation counters. Our eyes are greatly limited by sensitivity to only the visible range of electromagnetic energy. Because of these limitations, humans have continuously sought to develop the technological means to increase our ability to record the physical properties of our environment.

Beginning with the early use of aerial photography, remote sensing has been recognized as a valuable tool for viewing, analyzing, characterizing, and making decisions about our environment. In the past few decades, remote sensing technology has advanced on three fronts: from predominantly military uses to a variety of environmental analysis applications that relate to land, ocean, and atmosphere issues; from analogue photographic systems to sensors that convert energy from many parts of the electromagnetic spectrum to electronic signals; and from aircraft to satellite platforms.

Modern Advantages of Remote Sensing

Remote sensing technology is becoming more important in geography due to attention being paid to the latest information, planning, and management for public and private interests. It is most useful for natural resource management, sustainable development, environmental degradation, and disaster management. Its satellite data are used as basic inputs for the inventory of natural resources and development processes like agriculture, soil, forestry, and geology. There are other important technologies that are available to geographers as well, such as maps, aerial photography/photogrammetry/pictometry, SAR, LIDAR, SONAR, and GIS. Remote Sensing applications span a number of ecosystem types and environmental problems. Each f these has a number of agreements or frameworks for coordinated international action.

Remote Sensing of Environment serves the Earth observation community with the publication of results on the theory, science, applications, and technology of remote sensing studies. Thoroughly interdisciplinary, RSE publishes on terrestrial, oceanic and atmospheric sensing. The emphasis of the journal is on biophysical and quantitative approaches to remote sensing at local to global scales.

Areas of interest  include, but are not necessarily restricted to:


         Agriculture, forestry and range

         Biophysical-spectral models


         Geography and land information

         Geology and geoscience

         Hydrology and water resources

         Atmospheric science and meteorology

         Natural hazards

         Image processing and analysis

         Sensor systems and spectral-radiometric measurements

Our group works with remote sensing imagery that spans a broad range of temporal and spatial resolutions to develop products to characterize environmental features or input model parameters.
