Monitoring of water and land objects enters a revolutionary age with the rise of ubiquitous remote sensing and public access.

Bangladeshis in millions would be displaced due to global warming causing sea level rise by thermal expansion of the ocean waters and the melting of land- based ice.

Urbanization has been haphazard in Guwahati which has increased the chances of damage in the event of an earthquake and remote sensing technology will help reduce risks posed by quakes

Development of representative conceptual groundwater flow model is an important step before translating it into a numerical model. In this paper, a methodology for development of conceptual groundwater flow model has been presented in which spatially distributed values for groundwater recharge has been utilized instead of lump sum average values of recharge normally obtained by water budgeting method. The study also extensively uses GIS for preprocessing of hydrological, hydrogeological and geological data.

The preparatory work for Census 2011 began around the end of 2008. The first step was to unambiguously establish and finalize geographical boundaries for all administrative entities, viz., town, wards, districts etc. This "Census of India 2011: Provisional Population Totals" is Paper 1 of 2011 by NCT of Delhi (Series 8).

Mapping of extent of urban sprawl and by monitoring the temporal changes, the impact of changing land use on land, ecology and environment system can be assessed.

The amount and intensity of runoff at catchment scale are largely determined by the presence of impervious land cover types, which are predominant in an urbanized area. This paper examines the impact of different methods for estimating impervious surface cover on the prediction of peak discharges as determined by a fully distributed rainfall-runoff model (WetSpa). The study of River Yamuna and Hindon basin area shows detailed information on the spatial distribution of impervious surfaces, as obtained/calibrated from remotely sensed data.

In this present study, the soil erosion assessment and conservation measures in hill ecosystem is carried out in the Kalrayan hills, Part of Eastern ghats, Tamil Nadu using Remote Sensing and GIS techniques. The geocoded digital data of IRS P6 LISS – III (P101-R65 of 2001) and Survey of India toposheets (1971) were interpreted and various thematic maps such as drainage, lineaments, geomorphology, land use/land cover and slope maps have been prepared.

THIRUVANANTHAPURAM Where elephants will fear to tread, or will not fear to tread, is not something that can be foretold. But not any more.

BHUBANESWAR: Worried over the rising trend of elephant electrocution, the State Government on Thursday announced Rs 20-crore plan besides raising the crop loss compensation to Rs 10,000.
