The authors are studying the automatic reading and interpretation of color airial photographs by using the Ube Tech. College Picture Information Processing System. U-PIPS. The first results of this research we reported were regional division in color airial photographs which were achieved by differences in luminance and chromaticity. We had many satisfactory results. But this method strongly depends on the contents of the photographs and their types. Therefore, we tried another systematic method using Karhunen-Loeve transformation. A color airial photographs about 800 X 450 m in area was processed by this method. As a result, it was realized that this method uses the luminance, the bluish-red features and the greenish features, in order to identify a region. In this paper, several processed results are reported, including the extraction of a lake by isolating the greenish features as an example.
