GIS vs Remote Sensing | difference between GIS and Remote Sensing
This page compares GIS vs Remote Sensing and mentions difference between GIS and Remote Sensing. GIS stands for Geographical Information System. Remote sensing is done using satellite.
GIS | Geographical Information System
• The software program which enables users to store and manipulate large
amounts of data from GPS and other sources.
• It is software systems with capability for input, storage, manipulation/analysis. It displays geographic (spatial) information in various output formats such as maps, graphs or charts.
• It is a system which deals with all types of geographically referenced data.
• GIS software runs on powerful servers to mobile software.
• There are three common representations of spatial data used in GIS viz. vector, raster and triangulated.
Refer GIS basics and its benefits >> for more information.
• Remote sensing refers to use of satellites or aircrafts to capture information about
the earth's surface.
• Remote sensing satellites help in remote sensing of useful informations of the objects (i.e. earth).
• There are two types of remote sensing viz. active and passive.
• It is the science of deriving information about an object from measurements made at a distance from the object. Most of the remote sensing systems use electromagnetic energy emanating from objects of interest. Refer remote sensing technology >> and remote sensing satellites >> for more information.
