基于WebGIS技术的实测地层剖面数据Web发布系统设计与实现

Design and implementation of measured stratigraphic profile data publishing system based on WebGIS

我国在青藏高原开展了许多地质调查与矿产勘查工作,取得了大量的地质资料,但是这些珍贵的地质资料没有实现统一管理,不能实现共享,影响了为青藏高原经济社会发展的服务。因此,开展实测剖面数据库建设与数据Web发布系统的研究工作,可以全面摸清青藏高原地质资料数据分布情况,并通过基于Web GIS技术的实测地层剖面数据Web发布系统发布这些地质资料。通过这一系统,用户可以十分直观地了解已完成区域地质调查项目的实测地层剖面分布情况,了解每一条实测剖面的地理位置、所测地层、长度、生产单位、生产日期,观看剖面示意图,了解每一地层分段的岩石特征、化石种类、岩层厚度等,为用户提供地层剖面数据的检索与查询服务,以及地图查询、浏览、打印服务,同时还可以了解相关的地质背景知识。

Large amount of geological data are achieved in geological survey and mineral exploration projects ofQinghai-Tibet Plateau, and these need unified management and effective sharing for servicing the economic andsocial development in this underdevelopment area of China. The Web publishing system for measured stratigraphicprofile can exhibit and release spatial distribution characteristics and geological data in Qinghai-Tibet Plateaubased on WebGIS technology. We can visualize the major information of measured stratigraphic profile incompleted projects by this system, including location, measured strata, length, production entity, date, profile,and even rock characteristics, fossil species, and strata thickness. The Web publishing system provides services ofretrieval and query, map browsing and print, and introduction of related geological background.
