图象数字化
Examples
- Map digitizing data quality control method
地图数字化数据质量控制方法 - At present , the theory and application of topographical mapping system is quite mature . more of them reached the criterion of topographical map and the requirement of map digitizing . however , the deeper application and conversion of digital map to gis are ignored
目前，以单纯成图为目的测量绘图平台开发的理论和应用已经比较成熟，大多数的绘图平台已经基本实现了地形图图示上的绘图要求，能满足测绘部门数字成图的需要。 - Topographical maps are the principal frame form of gis , and realization map digitizing and offering gis basic spatial data is one of the important research fields in surveying and gis , which is also necessity of development of science and technology . based on building gis - oriented topographical mapping system theories , this themes apply the advanced objectarx technology , aim at topographical mapping and exporting to gis , and resolve several key problems , such as symbols analysis and building , dtm and contour line automatic drawing , topographical map adjoining , digital image rectifying etc . and it offers models and arithmetic , realizing the general functions of gis - oriented topographical mapping system
本文以建设面向gis的测量绘图平台理论为基础，以autocad平台下objectarx开发技术为核心，围绕地形图的成图和入库( gis数据库)这一课题，对其中的关键技术难题? ?符号库的建立与实现、 dtm与等高线的自动绘制、地形图接边、数字化栅格图像的定向与纠正、接口数据文件的生成等进行了研究分析，提出了相应的模型和算法，实现了面向gis的测量绘图系统的基本功能。 - Characteristic and application of gis firstly . secondly it introduced the designing frame of uiims , achieving of the sub - - function and the pattem of the application . it emphasizes on the principle of the map digitizing , the foundation of the data model and encoding means , the construction of the topology data structure , the theory of different format data convertion
本文首先介绍了地理信息系统的研究现状、技术背景、特点及应用；其次介绍了城市基础设施信息管理系统设计框架、具体功能的实现原理及应用模式，其中重点分析了地图数字化原理、数据模型的建立及其编码方法、拓扑数据结构的建立、不同格式的数据相互转换原理。
