WebThe TM data are scanned simultaneously in seven spectral bands. Band 6 scans thermal (heat) infrared radiation. A Landsat 4 or 5 TM scene has an instantaneous field of view (IFOV) of 30 meters by 30 meters (900 square meters) in bands 1 through 5 and band 7, and an IFOV of 120 meters by 120 meters (14,400 square meters) on the ground in band 6. WebIf you are looking for Land-Use/Land-Cover change detection, you will first have to classify your imagery (which I will not explain as it is a whole process in itself), and then do some sort of subtraction. Don't get confused though when I say subtraction - this is just one of many methods of change detection that you can do within ENVI.
