The purpose of this study is to create land use mesh maps in Asian mega cities such as Seoul, Taipei, Manila, and Bangkok. The method is as follows. First, 1 to 50,000 scale topographic maps of the four cities were collected and scanned as TIFF image files. Second, 1/2 standard mesh data in the urban areas of the four cities was created with using NIGMASX, Access, and ArcGIS. Third, dominant land use was made out and input as category data by 1/2 standard mesh. In doing so, land use was classified into nine items such as forest, grassland, paddy, other farmlands, industrial area, other built-up areas, water area, others, and sea. The creation of land use maps based on the same method can help us analyze urbanization process, developmental level, and their environmental impact, comparatively.
