Remote Sensing for environmental resource mapping

Remote sensing is the science and art of collecting, obtaining, analyzing, information of an impartial sensations or area acquired by a device that is not in contact with the purpose, zone or portents under research. Remote sensing is the outcome of development of science and technology. Although, it has wide range of application for environmental source investigation, supervision, demonstration and mapping. It is increasingly been used because of its different positive aspects such as repetitive use in all seasons with high accuracy in different context.

Remote sensing is the mechanisms, systems and devices to observe the earth's surface at a distance and to interpret the images obtain in order to acquire meaningful information of a particular substances on earth. The characteristics measured by a sensor are the electromagnetic energy reflected on emitted by the ground apparent. A true colorful is made sensitive to the primary colors by coating three separate color layers – blue, green, red. It is also cost effective inaccessible parts or areas such as, high altitude mountain at the time.

Geographic Information System (GIS) Technology for Natural Resource Management

GIS is a computer system designed for the acquisition, management, manipulation, analysis, modelling and display of geo referenced data for solving complex planned and a managed problem of natural resources. GIS is an interdisciplinary technology. GIS technology was developed in Canada. GIS system in regional planning. 

GIS technology is adopted by different organizations in Nepalese context, different departments, research institutions like Department of Forest and Soil Conservation, Department of Survey, Department of Geology, Local Development, Ministry of Population and Environment, different organizations relating to Urban Development. Department of Agriculture, ICIMOD, and many more.  

GIS technology is used for land capability classification, land use study as planning, activity relating to urban planning, service center location, different types of environmental studies, different types of environmental studies, different types of hazardless studies, preparation of different types of maps, different types of infrastructure development relating activities, different types of population studies and many more. 

The application of GIS has made the natural resource management activities effective and reliable. It makes the decision makers to make decision formulate policies and strategy developing models.
