Back-pressure is a logical mechanism to control the flow of information on a communication channel of a latency-insensitive system (LIS) while guaranteeing that no packet is lost. Back-pressure is necessary for building open LISs and it represents an interesting design alternative also for closed LISs because it makes possible to realize highly modular implementations with more predictable feat...

The IRS-1D LISS III false colour composite (FCC) decoded imagery belonging to Kosi river watershed of Almora district of Uttaranchal under warm humid Lesser Himalayan agro-ecological region was interpreted and surveyed for soil resource mapping. On the basis of image interpretation and ground truth study ten physiographic units were identified. Soil physiography relationship was established on ...

Pulicat Lake is one of the major wetlands in India. It is the second largest brackish water lagoon in India next to Chilika Lake in Orissa state. Pulicat Lake sits beside the Bay of Bengal so, the study on the mouth is vital. The investigations were carried out by using multi-temporal satellite imageries of IRS P6, LISS III data for four years viz., 2009, 2011, 2012 and 2013. Subsequent changes...

The objectives of this project are to create a spatial digital database consisting of LU/LC and road network maps with the help of IRS-ID, PAN & LISS-III merged data and SOI toposheets, to create database consisting of traffic volume, vehicle density and details of solid waste and to evolve an optimal transportation route maps for efficient, safe and economic disposal of solid waste. The final ...

Image fusion is a technique of obtaining high spatial resolution multispectral images from low spatial resolution multispectral and high spatial resolution panchromatic images. Various techniques exist to perform such fusion. These techniques, however, do not seem to preserve the spectral information content of original multispectral image in the fused image. Hence, in this study a recent and e...

Watershed prioritization is considered as the most significant aspect in watershed resource management and development program. The present work attempts to prioritize seventeen sub-watersheds Ruparel of Alwar district Rajasthan, India. For sub-watersheds, morphometric land use/land cover (LULC) analysis were performed using remote sensing GIS. Base map study area has been derived from SOI topo...

Digital image classification is generally performed to produce land cover maps from remote sensing data, particularly for large areas. The performance of image classifiers that utilize only the remote sensing data may deteriorate, especially in mountainous regions, due to the presence of shadows of high peaks. In this study, a multisource classification approach to map land cover in Himalayan r...

Recent dramatic bleaching events on coral reefs have enhanced the need for global environmental monitoring. This paper investigates the value of present high spatial resolution satellites to detect coral bleaching using a change detection technique. We compared an IRS LISS-III image taken during the 1998 bleaching event in Belize to images taken before the bleaching event. The sensitivity of th...

Water conservation becomes essential as the resource scarcer. The most important step in managing water resources is estimating watershed runoff generated from rainfall, and rainfall are key factors determining availability for surface storage groundwater recharge. So, this study mainly focused on three sub-catchments of Karamadai, Tamil Nadu, India, using heavy to extreme daily events received...
