Question

What is the difference between remote sensing and GIS?

Answer 1

Remote Sensing is a technique of capturing data using censors removed from the actual target site, like an airplane or satellite. The sensors can capture visual spectrum data (photographs) as well as IR and Roughness data (heat, radar).

This data is typically stored in what is known as a Raster format (tiff, jpeg, etc...) along with information about where that picture exists on the ground.

GIS is a system of displaying and analyzing geographic data. As Remote sensing data typically includes geographic information (coordinates of each cell in the picture), it can be easily integrated into GIS. While Remotely Sensed data is popular in GIS, Vector data in the form of layers like streets and rivers form another large portion of GIS Data, that is consider separate from Remote Sensing.

Answer 2

Remote sensing can be used in GIS, remote sensing is gathering information through satellite, plane, pigeon.  GIS utilizes information whether it be storing it, making maps, or analyzing it.
