An Overview of Remote Sensing

Remote Sensing is an extensive science, drawing from many areas for support and development. It depends greatly on the support of governments and private industries worldwide. Satellite and digital imagery play an important role in remote sensing; providing information about the land studied.

definition of remote sensing

An Introduction
Remote Sensing is the science and art of acquiring information (spectral, spatial, temporal) about material objects, area, or phenomenon, without coming into physical contact with the objects, or area, or phenomenon under investigation. Without direct contact, some means of transferring information through space must be utilised. In remote sensing, information transfer is accomplished by use of electromagnetic radiation (EMR). EMR is a form of energy that reveals its presence by the observable effects it produces when it strikes the matter. EMR is considered to span the spectrum of wavelengths from 10-10 mm to cosmic rays up to 1010 mm, the broadcast wavelengths, which extend from 0.30-15 mm.


Types

1. In respect to the type of Energy Resources:
   Passive Remote Sensing: Makes use of sensors that detect the reflected or emitted electro-magnetic radiation from natural sources.
   
   Active remote Sensing: Makes use of sensors that detect reflected responses from objects that are irradiated from artificially-generated energy sources, such as radar.
   
2. In respect to Wavelength Regions:
   
   Remote Sensing is classified into three types in respect to the wavelength regions
   • Visible and Reflective Infrared Remote Sensing.
   • Thermal Infrared Remote Sensing.
   • Microwave Remote Sensing.

Geogr aphic Information System Definition

GIS is a system of hardware and software used for storage, retrieval, mapping, and analysis of geographic data.  Practitioners also regard the total GIS as including the operating personnel and the data that go into the system.  Spatial features are stored in a coordinate system (latitude/longitude, state plane, UTM, etc.), which references a particular place on the earth.  Descriptive attributes in tabular form are associated with spatial features.  Spatial data and associated attributes in the same coordinate system can then be layered together for mapping and analysis.    GIS can be used for scientific investigations, resource management, and development planning.
GIS differs from CAD and other graphical computer applications in that all spatial data is geographically referenced to a map projection in an earth coordinate system.  For the most part, spatial data can be "re-projected" from one coordinate system into another, thus data from various sources can be brought together into a common database and integrated using GIS software.  Boundaries of spatial features should "register" or align properly when re-projected into the same coordinate system.   Another property of a GIS database is that it has "topology," which defines the spatial relationships between features.  The fundamental components of spatial data in a GIS are points, lines (arcs), and polygons.  When topological relationships exist, you can perform analyses, such as modeling the flow through connecting lines in a network, combining adjacent polygons that have similar characteristics, and overlaying geographic features.
