3 Demention Vector Contour

Abstract 3 Dimension Vector Contour of the whole national land have been produced based on surveys measured by Geographical Survey Institute, and the algorithm of its production, structure of National data and system structure for its usage are clarified in this report. The whole contour of Japan is integrated by UTM (Universal Transverse MERACATOR) drawing system containing 4717 drawing units. Contour pitch is 10 meter and accuracy (re3solution of height) is 1 meter. This report clarifies how to supply 3 Dimension Vector Contours to scientific use.
