Magic2 Scanning Charts 5655 — Version 2.0

This document represents the digitisation by the CNR-IGAG of one of the 59 sounding graphs belonging to the Hydrographic Institute of the Navy (IIM) and by their georeferences. The digitisation methodology has been agreed with IIM technicians, using a very high-resolution video work scale in order to ensure that the digital quoted point falls within the area represented by the graphic point or at most at a distance equal to the size of the point itself. The points thus obtained were then returned to the IIM for their final endorsement.本文件记录了意大利国家研究委员会地球科学与地球资源研究所（CNR-IGAG）对隶属于海军水道测量局（Hydrographic Institute of the Navy，IIM）的59份水深测图之一及其地理参考数据的数字化工作。本次数字化作业流程已与IIM技术人员共同商定，采用超高分辨率视频工作标尺开展作业，以确保数字化采集点落在原图图形点所代表的区域内，至多与该图形点的间距不超过其自身尺寸。所得采集点随后将提交至IIM进行最终审核确认。
