摘要
特殊环境地区的数据库管理是一项重要且复杂的综合性工作,传统关系型数据库对海量气象观测数据与矢量数据的整合管理存在一定限制,尤其是在空间关系与分析上.为此以腾格里沙漠公路为研究背景,基于ArcGIS地理空间数据库(ArcGIS Geodatabase)实现空间数据库的构建,依不同要素类型划分图层单元实现沙漠地区数字地图的矢量化,通过概念框架设计、逻辑模型构建、物理分层设计、数据库实施,使多种类型数据互相关联、集成于同一数据库中.这一地理空间数据库不仅具有传统数据库储存和管理数据的性质,更对所储存的空间图形数据和属性数据二者建立起了联系,实现特殊环境下的数据可视化管理、风沙情况分析、空间分析、专题图制作等功能,能够为空间数据和资料的分析提供有效支撑.
The database management of special environment area is an important and complex comprehensive work.The traditional relational database has some limitations on the integration management of massive meteorological observation data and vector data,especially in the spatial relationship and analysis.In this paper,Tengger desert is taken as the research area,based on ArcGIS geo database realizes the construction of spatial database,layer units is divided according to different element types,and the vectorization of digital map is realized in desert area.Through conceptual framework design,logical model construction,physical hierarchical design and database implementation,multiple types of data are interrelated and integrated in the same database.This geospatial database not only has the nature of traditional database storage and management data,but also establishes the connection between the stored spatial graphic data and attribute data,realizes the data visualization management,sand situation analysis,spatial analysis,thematic map production and other functions under the special environment,and provides effective support for the analysis of spatial data and data.
