Course Goals

•^

ERS

: to be able to read and evaluate remote

sensing literature in the context of a mechanisticunderstanding of RS principles and technology.– Secondarily, you MUST know the difference between

GPS, GIS and RS!

•^

ERS186L

(Spring): to be able to perform basic

remote sensing research (project design, datacollection, image acquisiton, image analysis,presentation of results).

What Is Remote Sensing?

•^

From your text:– Minimal definition (much better): “remote sensing is

the noncontact recording of information from theultraviolet, visible, infrared, and microwave regions ofthe electromagnetic spectrum by means ofinstruments such as cameras, scanners, lasers, lineararrays, and/or area arrays located on platforms suchas aircraft or spacecraft, and the analysis of acquiredinformation by means of visual and digital imageprocessing.”

What Is Remote Sensing?

• Some thoughts:

– We are NOT going to focus on visual

interpretations, rather we will focus on digitaltechnologies. Photogrammetry (visual/analogremote sensing) can be learned in ERS185.

– Remote sensing is an

applied science

and is

a tool to help understand other fields such asecology, climatology, geology, soil scienceand hydrology.
