LANDSAT 4 investigations of thematic mapper and multispectral scanner applications

Progress in the investigation of the quality and performance of LANDSAT 4 TM data is reported. Average mean brightness values were computed for each band and a look-up table was designed to place the values at about 1.0 density on the straight line portion of the film's H and D curve. Manual interpretation of bands 5 and 7 indicated these data to be good sources for determining locations of dugouts and small ponds as water sources
