Abstract
A seamless geological map with unified legend was created at the scale of 1:200,000 covering the entire Japanese Archipelago. This was accomplished by harmonizing regional geological maps that were compiled in various ages. A research scenario from basic geological research to information technology (IT) for distribution of digital geological maps was designed. Type 2 Basic Research was proposed to distribute the interoperable data set of geological maps, which were transformed from the results of Type 1 Basic Research for geological mapping. Seamless geological mapping was finally proposed as a Full Research program in geological research field.
