Land Surface Temperature Estimation using Landsat ETM+ Data
Abstract: Land Surface Temperature (LST) can be estimated from remotely sensed satellite data. LST is a key parameter in the physics of land surface processes because it is involved in the energy balance as well as in the evapo-transpiration and desertification processes. The knowledge of surface temperature is important to a range of issues and themes in earth sciences central to urban climatology, global environmental change, and human-environment interactions. In this …

Use of LANDSAT ETM + Data for Detection of Prosopis juliflora in Irrigated Zones
Abstract: Prosopis juliflora (PJ) can be used as a relevant indicator for integrated management of irrigated saline soil in arid zones. Remotely Sensed Landsat Enhanced Thematic Mapper Plus (ETM+) dataset was used for detection and delineation of areas under PJ. The vegetation densities were classified using normalized difference vegetation index (NDVI) whereas soil moisture levels were estimated based on distribution of soil wetness index (SWI). The classified NDVI map was combined …

A Comparative Study of Statistical Features for Satellite Images with Natural Images
Abstract: While satellite imaging involves several bands that capture the geographical features, the natural images taken from camera in real world uses RGB model, which is composed of three channels, where each image can store discrete pixels with conventional brightness intensities between 0 and 255. So, the uniqueness of the two imaging techniques is reflected in its bits of every pixel. It is well known that the whole information of an …

Integrated Geospatial Technology for Appraising Surface Temperature and Forest Biomass in Context to Conducive Tiger Habitats in Sariska Wildlife Reserve, India
Abstract: Sariska Wildlife Reserve of Rajasthan (India) is an excellent wildlife habitat, but due to improper conservation, anthropogenic activities and human-wildlife conflicts, the number of tigers started dwindling in the middle 1990s and completely disappeared during 2005. The forest temperature and forest biomass are vital parameters in several forest-related issues and has an apparent relationship to wildlife habitat and conservation strategies. Satellite remote sensing data being the best possible way for …

Application of Remote Sensing and GIS Techniques for Decadal Change Detection of Mangroves along Tamil Nadu Coast, India
Abstract: Mangrove forests are among of the most productive and biologically important ecosystems of the world. The mangrove forests aids stabilize shorelines and reduce the devastating impact of natural disasters such as tsunamis and hurricanes. They also provide breeding and nursing grounds for marine and pelagic species, and food, medicine, fuel and building materials for local communities. Despite of its immense importance, it is declining due to increasing coastal population, urbanization …

Assessment of Temporal Features for Geographical Localisation of Satellite Images
Abstract: AbstractMost of the geographical applications are dependent upon the frequent interpretation or analysis of satellite images captured at periodical manner. Consequently the observation is mainly due to the environmental or human based comprehensive changes in spatio-temporal information, which affect the overall process. Thus the past and present data are main sources in the various predictive investigations in remote sensing. While inherent spatial and spectral information are exploited severely, it is …

Mapping of Crop Management Factor (C) for Sylhet Sadar using Remote Sensing and GIS
Abstract: Sylhet Sadar suffers from excessive rainfall causing the enormous soil loss in this area. C-factor is one of the most important parameter of the Universal Soil Loss Equation (USLE) and revised version of USLE for estimating soil loss. The current study was conducted for determining the crop management factor (C) using remote sensing (RS) and geographical information system (GIS) tools. Satellite images (Landsat 7 ETM+ of 2000, 2010 and Landsat …

Glacier Volume Changes and Their Climatic Causes in Tirungkhad Basin Located in Western Himalaya
Abstract: Normal 0 false false false EN-IN X-NONE X-NONE In the Himalaya, a significant number of glaciers are shrinking due to climatic variations. Monitoring of these glaciers is important to assess future availability of water resources. However, Himalayan glaciers are normally difficult to monitor due to the rugged, mountainous terrain. Therefore, in the present study, Survey of India (SOI) topographical maps (1966) and Landsat datasets as ETM+ (2000, 2006) and TM …

Study on Land Use/Land Cover Change Dynamics through Remote Sensing and GIS – A Case Study of Kamrup District, North East India
Abstract: The study describes the land use and land cover dynamics in Kamrup district of Assam from 1991 to 2011 using remote sensing and Geographical Information System (GIS). Satellite remote sensing and GIS acts as an effective approach for analyzing the direction, rate and spatial pattern of land use dynamics. Landsat-TM and ETM+ for the period 1991, 2001 and 2011 were used to prepare the land use/land cover (LULC) map for …
