The present study was carried out in view of the industrial development and geographical changes of the Inchon area, near Seoul, Korea. The time series observations by Landsat have revealed that the salt fields in this area have remarkably decreased over the past decade, though there was almost no significant salt field reduction in the preceding four decades. The process of the salt field reduction on this area was displayed in the classified time series image from 1972 to 1988 with a view of making raster type GIS data files. The changes of coast lines were clearly revealedby overlaying old maps on the time series images. For Better visual demonstration of the changes of land coverage, these GIS data files were overlayed after rating with a special care. This procedure is probably available to make many types of thematic maps as well as GIS data base for various purposes.
It has been also found that the salt fields in the Inchon area have been being reclaimed as industrial sites, as ever seen in Seto Inland Sea area from the 1960's through 70's in Japan.
