Abstract
Geological Survey of Japan has published and dizitized many kind of geological maps. The dizitized maps are procesed on GIS(Geographical Information System) for the use of education, civil engineering, enviromental problems, mitigation or geological hazards so on.
We developed a simple GIS software GeomapZ for viewing and analyzing geological data. GeomapZ can read data from DLG-formatted vector data files. DEM-formatted elevation data files, raster image data files in BMP/TIF, and user data in text format. It is easy to create and to print high quality geological images using GeomapZ. GeomapZ is a suitable and easy viewer particularly for publication of geological data in the way with CD-ROM.
