• GPS (global positioning system)– Car GPS systems, yield monitors, smart phones
• RS (remote sensing)– Satellite or Aircraft imagery (Including UAS)– Your camera
• GIS (geographic information system)– Combines layers of information– Can include GPS and RS information– Provides analytic tools– ArcGIS, ArcGIS Online, QGIS, GoogleEarth?

What Is Remote Sensing (RS)
Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites.

Comparison of Spectral ResponsesResponse from Grass Area
Response from Football Field
Channel numbers in order of blue, green, red, near infrared red
• Notice the difference in channel 4 or the near infrared band
• Use of near infrared was very helpful for camouflage detection during World War II
• Any thoughts on how else these type of response differences can be used?
