Remote sensing: A tool for sustainable environment

Author(s):

Abstract:
Remote sensing is an important method of earth observation from out of space using satellites. Satellite sensors can constantly observe the earth’s surface and with the development of remote sensing science, it has become an important mechanism to determine spatial and temporal land surface information quantitatively based on the principle of electromagnetic spectrum. It records the electromagnetic energy reflected or emitted by the earth’s surface. The amount of radiation from an object (called radiance) is influenced by both the properties of the object and the radiation hitting the object (irradiance). High level remote sensing products are urgently needed to meet global changes and for many other applications. Generating these high level products is challenging, however and has become a hot research topic. Remote sensing imagery has many applications in mapping land-use and cover, agriculture, soils mapping, forestry, city planning, land degradation, archaeological investigations, military observation, land cover changes, deforestation, vegetation dynamics, water quality dynamics, droughts, floods, urban growth, forest fires, etc. This paper overview the use of remote sensing as tool to can get frequent and sustained information of the earth surface which can further utilized for the sustainability of the ecosystem services provided by the earth.
