Magic2 Scanning Charts 0380 — 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质资源研究所（CNR-IGAG）对隶属于海军水文研究所（IIM）的59幅测深图中的一幅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操作，以确保数字化标记点位完全落在原图表点位的表示范围内，最大偏差不超过该图表点自身的尺寸。所获取的全部点位随后将提交至IIM进行最终核准。
