Linguistic Atlases seem to be roughly devided into two kinds. One is a map descrived by dialectical phenomena and the other is the atlas of signs. This sign-atlas that came from Marburg University in Deutsch, may be more familiar than that. Two different methods of a legend style are found, too in Japan. One is a KOKURITSUKOKUGO-KENKYUSHO method, the other is the HIROSHIMA-GAKUHA method. The latter is the legand which means "the structure of dynamic relation of the local languages".
