The images depicted below are of the Lloyds Harbor area on the North Shore of Long Island. All three images are from a single satellite image of the area using a variety of band combinations. TM data is acquired in seven separate bands. Each band represents a slice of the electromagnetic spectrum. Any of these bands can be displayed using the three color guns Red, Green, and Blue.
Different combinations highlight different types of ground cover.
Thematic Mapper data has a spatial resolution of 30 meters. Each pixel represents a 30 square meter area on the ground. TM band wavelength ranges are listed below A larger version of each of the images below can be displayed by clicking on the image.
