Magic2 Scanning Charts 5571 — 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.本文件记录了由CNR-IGAG完成的工作：对隶属于意大利海军水文研究所（Hydrographic Institute of the Navy，缩写IIM）的59幅测深图中的单幅图开展数字化处理，并完成其地理配准。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进行操作，以确保数字化标注的点位完全落在原图图形点位覆盖的区域内，最大偏差不超过该点位自身的尺寸。所获取的全部点位随后将提交至IIM，以待其完成最终审核确认。
