摘要

摘要:本文将13世纪末至16世纪末制作的12张波尔多兰海图上亚得里亚海海盆的几何形状与现代地图进行了比较，采用赫尔默特变换以保留其原始几何形状，并在每张海图上使用相同的40个相同的点。在研究的第一阶段，将portolan图表的几何形状与六个选定的地图投影进行比较，以确定几何形状的“最佳拟合”。在第二阶段，绘制在图表上的线网按区域和功能划分，并与“最佳拟合”地图投影进行比较，以确定更详细的几何模式。研究结果表明，亚得里亚海海盆在portolan海图上的绘制可能是有意采用与现代共形柱(Mercator)投影在几何上最相似的地图投影的结果。

Conformal Cylindrical Properties of Adriatic Sea Basin Renderings on Portolan Charts

ABSTRACT The geometry of Adriatic Sea basin renderings on 12 portolan charts made from the late thirteenth to the late sixteenth century was compared to a modern map by applying Helmert transformation in order to preserve their initial geometry and by using the same 40 identical points per chart. In the first stage of the research, the geometry of the portolan charts was compared to six selected map projections in order to determine the geometrical ‘best fit'. In the second stage, networks of lines plotted on charts were divided regionally and functionally and compared to the ‘best fit’ map projection to determine their geometric patterns in more detail. The research results showed that Adriatic Sea basin renderings on portolan charts were probably the result of a deliberately applied map projection which was geometrically most similar to the modern conformal cylindrical (Mercator) projection.

期刊介绍： The Cartographic Journal (first published in 1964) is an established peer reviewed journal of record and comment containing authoritative articles and international papers on all aspects of cartography, the science and technology of presenting, communicating and analysing spatial relationships by means of maps and other geographical representations of the Earth"s surface. This includes coverage of related technologies where appropriate, for example, remote sensing, geographical information systems (GIS), the internet and global positioning systems. The Journal also publishes articles on social, political and historical aspects of cartography.
