摘要
Abstract
In order to adapt to the GIS construction of Tianjin Port,it is necessary to convert the traditional CAD data to the standard format of GIS data. Due to the mapping method and habit,the irregular point and theline in CAD data;unclosed polygons and disorder figures of layers and in the layer for a long time,the structure of CAD data and GIS data are much different. It is too hard to transplant CAD data to GIS data entirely. Basing on the analysis of the questions in the process of CAD data transplanted to GIS data,the logical structure of the CAD data of Tianjin Port, the design of the layers and attributes are deeply discussed in this paper.关键词
