Lab 2 Part 2- Multispec

Exercise 1: Changed around the image map parameters, overview of how to use Multispec

Exercise 2: Gives you step by step directions on how each setting works and how to use them, we enhanced the image in this exercise

Exercise 3: Created a cluster map, the colors changed and the pixels were sorted into clusters. compared the cluster map I created to the original image.

Exercise 4: Created training areas for specific classes. Used the project created from exercise 3

Lab 2 Part 1- Remote Sensing

             Remote sensors collect data by detecting the energy that is reflected from eather. So the information is gained without making physical contact with the object. These sensors can be on satellites or mounted on aircrafts. Pictures taken by remote sensors can be used to prepare for hazardous events. Remote sensing makes it possible to collect data on dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation in areas such as the Amazon Basin, glacial features in Arctic and Antarctic regions, and depth sounding of coastal and ocean depths. Military collection during the Cold War made use of stand-off collection of data about dangerous border areas. Remote sensing also replaces costly and slow data collection on the ground, ensuring in the process that areas or objects are not disturbed.

There are two types of remote sensors: passive active. Passive sensors record radiation that is reflected from Earth’s serfuce, usually from the sun. Passive sensors can only be used to collect data during daylight hours. Examples of passive sensors are photography, infrared. Active sensors use internal stimuli to collect data about Earth. Examples would be a laser beam remote sensing system projects a laser onto the surface of the Earth and measures the time that it takes for the laser to reflect back to its sensors.
