Any information system is normally a computer-based information system that enables capture, modeling, manipulation, retrieval, analysis and presentation of geographically referenced data. The rise of information technology and its use in a wide range of disciplines provides transportation and air quality modelers with a powerful tool for developing new analysis capability.

In recent years, conservationists have increasingly used satellite imagery based analyses for planning. We used forest plots and satellite image analysis to study the same landscape of forests used and managed by Wounaan indigenous peoples in eastern Panama.

In this study, an attempt was made to define the optimum set of spectral narrowbands and the required bandwidth for agricultural applications. Spectral observations were collected using ASD handheld spectroradiometer (325

Landscape changes were measured in two watersheds of western Himalayas over a period of 17 years using satellite images. Whereas the total forest cover was found to have been altered, there was substantial shift

Kolleru, the largest freshwater lake along the east coast of India in Andhra Pradesh (AP) had been encroached, mainly for aquaculture, to such an extent that most of the lake area was highly compartmentalized by 3

Masjed-i-Soleiman (MIS) is situated in the northern part of the Dezful embayment, which is in the Zagros fold

A globally consistent methodology using satellite imagery was implemented to quantify gross forest cover loss (GFCL) from 2000 to 2005 and to compare GFCL among biomes, continents, and countries. GFCL is defined as the area of forest cover removed because of any disturbance, including both natural and human-induced causes.

An evaluation for the development work done in the two watersheds, viz. Bunga and Dabkauri in Panchkula District, Haryana was carried out for 2004 and 2007. Satellite digital data of LISS-IV sensor for 2004 and

To achieve sustainable development and to ensure water availability in hydrological basins, water managers need tools to determine the actual evapotranspiration (ET) on a large scale.
