cartographic

1·The purpose of the thesis is to utilize UML to improve GIS figure modeling and apply to figure modeling course with GIS linear data simplifying and automatic cartographic generalization.

本文的目的是利用UML改进GIS图形建模，并运用于对自动制图综合和GIS线状数据的简化的图形建模过程。

2·The study on automated cartographic generalization has little breakthrough due to the lack of depth of generalization knowledge gained nowadays.

自动制图综合的研究长期以来未能取得突破性进展，原因之一是人们对制图综合的知识处理的深度不够。

3·Therefore, an ideal frame is established for cartographic expert system of qualitative information.

从而为定性信息的制图专家系统建立了一个思维框架。

4·The comprehensive classification (assessment) of multi-thematic data in thematic cartography is an important content of cartographic data processing.

专题制图中，多专题数据综合分类(评价)是制图数据处理中的重要内容。

5·These changes involve the resources of mapping data, cartographic production process, map representations and map functions.

这些变化涉及制图数据来源、制图生产过程、地图表现形式乃至地图功能诸多方面。

1·This article analyses the theory of continuous bitmap image's geometrical transformation, and makes attempts in cartographic jointure, dot character's stepless transformation on the basis of it.

分析了连续位图图像几何交换的理论基础，并在此基础上时地图拼幅，点阵字符的无级处理等方面做了一些尝试。

2·The analytic function of GIS and the cartographic function of Computer assisted cartography (CAC) are two aspects of geographic spatial data application.

地理信息系统(GIS)的地学分析与计算机地图制图(CAC)是地理空间数据应用不可分割的两个方面。

3·Constructing cartographic model is helpful to make complex system simplified and comparison is a main stage of model construction.

建立地图模型，有助于使复杂系统简单化，而比较是建立模型的主要环节。

4·So the study of automatic cartographic generalization in the web environment is of the utmost urgency.

因此，对网络环境下的地图自动综合进行探索与研究已经迫在眉睫。

5·It is one of the most important factors in cartographic generalization to accept or reject geographic elements.

地图综合的重点是地理要素选取与图形概括。
