This article explores the differences between GIS (Geographical Information System) and Remote Sensing.

GIS stands for Geographical Information System. Remote sensing, on the other hand, typically involves using satellites.

What is GIS (Geographical Information System)?

GIS-Geographical Information System

A GIS is a powerful tool for managing and analyzing geographic data.

  • It’s a software program that allows users to store and manipulate large amounts of data from GPS and other sources.
  • GIS are software systems capable of input, storage, manipulation, and analysis.
  • It displays geographic (spatial) information in various output formats such as maps, graphs, or charts.
  • Essentially, it’s a system that deals with all types of geographically referenced data.
  • GIS software runs on everything from powerful servers to mobile devices.
  • There are three common ways spatial data is represented in GIS: vector, raster, and triangulated.

What is Remote Sensing?

remote sensing

Remote sensing uses satellites and aircraft to gather information about the Earth.

  • Remote sensing involves using satellites or aircraft to capture information about the Earth’s surface.
  • Remote sensing satellites are valuable for gathering information about objects (i.e., the Earth) from a distance.
  • There are two main types of remote sensing: active and passive.
  • It’s the science of deriving information about an object by taking measurements from a distance. Most remote sensing systems use electromagnetic energy that comes from the objects being observed.
