THE DISPLAY OF LANDSAT DATA AT LARGE SCALES BY MATRIX PRINTER

Lineprinter images of digital Landsat multispectral data may be conveniently and economically displayed on standard line-printer paper by using a matrix printer. DOTPRINT images at nominal scales of 1:24,000, 1:50,000, and I:62,500 are produced. These images may be compared with maps and aerial photographs to locate terrain features within about a 1 percent scale error. Other smaller scales may be produced by averaging row-by-column pixels. More precise geometry is obtained by using control points and regression equations which permits features to be located to the nearest half-pixel over an area the size of a 15-minute quadrangle. Color infrared images and color classifications (geological maps) may be produced from several DOTPRINTs by overprinting channel- or ratio-images of different colors on the same piece of paper.
