摘要:

基于不同的应用目的,由不同单位采集的同一区域的综合地下管线数据与专业地下管线数据在数据模型、位置精度与属性信息等方面存在一定差异,由此产生的“两套数据、两个系统”的管理模式,严重影响了不同单位间管线数据的集成融合与共享交换。本文结合两类管线数据的特征,构建了管线层次匹配模型,开发了城市地下管线空间数据匹配系统,为城市地下管线数据的集成与融合提供软件支撑,促进管线空间数据的共享与深层次应用。

关键词: 城市地下管线, 层次匹配模型, 骨架线, 相似性

Abstract:

Based on different application purposes,there are some differences in data model,location accuracy and attribute information between the integrated underground pipeline data and professional underground pipeline data which are collected by different departments.As a result,there are two sets of data and two systems.This management model has seriously affected the integration and sharing of pipeline data between different departments.In the light of the characteristics of the two types of pipeline data,this paper constructed the pipeline hierarchical matching model,and developed the urban underground pipeline spatial data matching system,which provides software support for the integration of urban underground pipeline data,and promotes the sharing and deep application of it.

Key words: urban underground pipeline, hierarchical matching model, skeleton line, similarity
