Assessing Long Term Stability of Landsat 5 TM, Landsat 7 ETM+ and Landsat 8 OLI
, 2017 The radiometric calibration stability of Landsat 5 (L5) Thematic Mapper (TM), Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) and Landsat 8 (L8) Operation Land Imager (OLI) is continuously monitored, trended, and updated using various on-board and vicarious calibration techniques. The on-board calibrators in L5 TM and L7 ETM+ were deemed unreliable

Irrigated lands assessment for water management: Technique test [PDF]
A procedure for estimating irrigated land using full frame LANDSAT imagery was demonstrated. Relatively inexpensive interpretation of multidate LANDSAT photographic enlargements was used to produce a map of irrigated land in California.

Computer Mapping of Water Quality in Saginaw Bay with LANDSAT Digital Data [PDF]
The author has identified the following significant results. LANDSAT digital data and ground truth measurements for Saginaw Bay (Lake Huron), Michigan, for 31 July 1975 were correlated by stepwise linear regression and the resulting equations used to ...
