ETM+ (Enhanced Thematic Mapper Plus)

Flown onboard Landsat 7.

Applications: land use/land cover; environmental monitoring; climatology; oceanography; ice and snow cover; coastal studies; soil.

The ETM+, the latest in a series of instruments flown onboard the Landsat satellites, has 7 spectral bands covering the visible, near infrared, shortwave, and thermal infrared; the panchromatic (visible to near infrared) has a pixel size of 15 m, while the thermal infrared band has a pixel size of 60 m, all others have a pixel size of 30 m.

On a rare fog free day Landsat 7 flew over 
            San Francisco and produced this stunning true color image. You can 
            easily see both man made structures–the Golden Gate Bridge, the 
            Bay Bridge, Alcatraz, and Oakland International Airport–and natural 
            features such as the Marin Headlands and the complex currents in San 
            Francisco Bay. This image was provided by the EROS Data Center Landsat 
            7 Data Handling Facility Image Assessment System (IAS)
