Abstract

Now we are introducing the design and specifications of a new web-based database of archaeomagnetis in Japan and the plan of publishing the database as a web service. The targets of this service are researchers of geomagnetism / paleomagnetism, researchers and investigators of archeology, people related to education, students and general citizens. Our web service will provide the information of archeomagnetic dataset, locations and eras with search engine and map.
