The Landsat sensors - EOSAT's plans for Landsats 6 and 7
Abstract
This paper describes the design configuration of the Enhanced Thematic Mapper (ETM) sensors that are presently under construction for Landsats 6 and 7. The paper begins with a brief introduction to EOSAT and a status report on the Landsats 4 and 5 operations, followed by an overview description of the Thematic Mappers that are currently flying on Landsats 4 and 5. The enhancements to the Landsats 6 and 7 Thematic Mappers are then described in some detail, including the implementation of a panchromatic band of detectors providing 15 m spatial resolution for both ETM sensors. The Landsat-7 ETM may include as many as five bands of thermal detectors with 120/60 m spatial resolution; the implementation and performance of this option will be discussed. The paper also provides a brief description of two new sensors that are being considered for Landsats 6 and/or 7: a low-resolution (500 m), wide-field sensor (a Regional Mapper) with the Thematic Mapper's spectral coverage, and a high-resolution (10/20 m), narrow-field, pointable Advanced Landsat Sensor (ALS) utilizing multispectral linear array technology.
