urbanization and population growth along with an increase in the environmental pollution resulting from human activities which have dramatically changed the green space and land cover have been key factors in the sustainable development of land and the management of land use. to collect reliable data required for providing land cover maps as well as for investigating the environment, remote sen...

nowadays, remote sensing comes under the title of management method for precision farming. for provision of the land cover and therefore land use map use must be made of satellite images. for an assessment of the type of agricultural crops it is required to have satellite images of high resolution. from specifications of the satellite images one is to produce maps with varied scales. in this re...

Soil Informatics, the GIS-based decision-support system, helps to establish the potentials and limitations of different soils for crop production. A new methodology combining soil survey indices with available nutrients (P and K) was developed to evaluate soil productivity. Physiographic-soil map was generated by interpretation of IRS 1C/1D LISS III satellite data and soil survey in an agricult...

The mountainous state of Himachal Pradesh is known for its vast natural wealth, including forests, alpine meadows, rivers and valleys endowed with a rich array of life forms. However, this biodiversity hot spot is under great peril owing to human-induced disturbance factors. The findings on spatial representation of the habitat at a scale which can be used for conservation planning and rehabili...

Indian cities are experiencing an accelerated pace of growth since independence and are now emerging as centres of domestic and international investments in an era of economic reforms, liberalisation and globalization. This has created opportunities for technologists and planning professionals to guide and develop the process of planned development and management utilizing modern technologies. ...

Indian Ocean is the home to rare flora and fauna that act as the bio-shield to many coastal communities. Indian Ocean experienced the world’s most deadly natural disaster “Tsunami” on 26 December, 2004, which on one hand is unparallel in the history considering its magnitude and devastation and on the other hand, caused an unprecedented impact on the aqua and aqua terrestrial ecosystems. One of...

Systems design consists of both geometry-based three-dimensional (3D) and energy-based one-dimensional (1D) models. Automatically synthesizing 1D and 3D models from the same specification is useful because it saves time and eliminates errors. State-of-the-art synthesis algorithms use a one-to-one mapping of 3D to 1D artifacts and therefore only cover the geometric aspects of the design. In this...

Land cover is one of basic data layers in geographic information system for physical planning and environmentalmonitoring. Digital image classification is generally performed to produce land cover maps from remote sensing data,particularly for large areas. In the present study the multispectral image from IRS LISS-III image along with ancillary datasuch as vegetation indices, principal componen...

Path radiance due to aerosols plays an important role over satellite derived reflectance due to higher aerosol optical depth and their seasonal variations. In addition, satellite data from high-resolution sensors are subjected to adjacency effect, which reduces apparent surface contrast by decreasing the top of the atmosphere radiance over bright pixels and increasing the brightness of the dark...
