Abstract

Landsat-7 Enhanced Thematic Mapper Plus (ETM+) sensor offers several
enhancements over the Landsat-5 Thematic Mapper (TM) sensors, including increased
spectral information content, improved geodetic accuracy, reduced noise, reliable
calibration, and matching scenes were recorded by both, and improved spatial resolution
of the thermal band. In this paper, we present some comparisons between Landsat-7
ETM+ and Landsat-5 TM imagery in order to quantify these improvements. Practically,
we find that the ETM+ continues the record of TM observations, and, in many respects,
substantially improves upon the earlier sensor. Specific improvements include lower
spatial noise levels, improved information content, and geodetic accuracy of
systematically corrected products to 50–100 m. These improvements are likely benefits
for land-cover mapping and change detection applicat
