Geographic Information System (GIS) plays a vital role in collecting or analyzing land-use/cover change information for environmental impacts and infrastructure management. One of the major problem associated with high spatial resolution (56 square meter/pixel) sensors such as AWiFS that is characterized by low temporal resolution (5 days/cycle), limits the(More)
Detection of Earth surface changes is essential to monitor regional climatic changes, avalanche hazard analysis and energy balance studies that occurs due to air temperature anomalies. Geographic Information System (GIS) enables such research activities or procedures to carry out through change detection analysis. From this perspective, different change(More)
Remote sensed information is a primary source of oversee Land-Use/Land-Cover (LULC) changes for environmental impacts, natural hazard analysis and region planning. Change Vector Analysis (CVA) as change detection technique has level headed capability of extracting and identifying LULC changes in terms of change-magnitude and change-direction from two(More)
Remote sensing provides the facility of acquisition of data associated with Earth's surface to observe regular changes. An important characteristic of imaging sensor is resolution which is classified in four different ways: (a) spatial; (b) spectral; (c) radiometric; and (d) temporal. During recent decades, the emergence of multispectral sensors provides(More)
Remotely sensed data is only a key source of detection of Earth's surface changes or Land-Use/Land-Cover (LULC) monitoring. During past decades, a series of effective change detection techniques such as Principal Component Analysis (PCA), Change Vector Analysis (CVA) and Post Classification Comparison (PCC), have been developed to observe the LULC(More)
The present study deals with analysis of different topographic corrections over north Indian Himalayan. Remote sensing is only the possible solution to monitor temporal variations by acquiring information on nearly daily basis concerned with Earth surface. In order to monitor the regional climatic changes, some corrections need to be performed on acquired(More)
