Remote sensing refers to the activities of recording, observing, and perceiving (sensing) objects or events in far-away (remote) places. In remote sensing, the sensors are not in direct contact with the objects or events being observed. Electromagnetic radiation normally is used as the information carrier in remote sensing. The output of a remote sensing system is usually an image representing ...

Based on remote sensing images, the panoramic views of land coverage distribution across a large geographic area can be accessed conveniently. Remote sensing monitoring system of land coverage change in mining area, which is a complex information system based on spatial database to manage multi-source heterogeneous data, was proposed in this article. The system structure, function and developme...

water plays a vital role in the development of activities in an area. the surface water resources are inadequate to fulfill the water demand. productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

The ratio of leaf area to ground area (leaf area index, LAI) is an important state variable in ecosystem studies since it influences fluxes of matter and energy between the land surface and the atmosphere. As a basis for generating temporally continuous and spatially distributed datasets of LAI, the current study contributes an analysis of its spatial variability and spatial structure. Soil-veg...

INTRODUCTION Telecommunication infrastructure is being rolled out across Australia with little knowledge about the uptake by health professionals in remote areas. Computer mediated communication has the potential to offer educational support to remote practitioners; however, the viability of this is uncertain. The aim of this research was to establish and evaluate an internet-based resource lib...

the aim of this research was to evaluate some soil physical quality indicators using remotely sensed date, gis and geostatistical methods in baft area that is one of the most important centers of agricultural production in kerman province. therefore, soil samples were collected from 0 to 20cm depth of 183 points based on regular sampling pattern (every 250 meters) and soil physical indicators i...
