最終版伊能中図北海道における伊能忠敬の測量成果の寄与. (Javanese)

Ino maps of the final edition completed in 1821 cover the whole Japanese Islands including Hokkaido and the belonging islands. However, Ino Tadataka surveyed the southern coast of the Hokkaido only once 1800. Comparing the final edition map and the map completed in 1804 which was drawn only by his own survey, contribution by Ino can thus be separated. We conclude that the results by Ino, for example, azimuth measurements to mountain summits and traverse line surveys along coasts, although these two are main parts of Ino works, are not used in the map of Hokkaido of the final edition. Place names too were newly collected by someone. Only the latitude values obtained by Ino with astronomical measurements of culmination altitude of stars were used for the final edition.
