基于GIS的林业数据库系统架构与实现

随着数字林业的发展,空间数据不断引入,增大了森林资源数据库的数据量,这给应用系统的运行效率带来了挑战。如何有效地组织数据,制定查询优化策略,已经成为森林资源数据库应用系统设计中的关键问题。本文以浙江省诸暨市林业资源为数据源,基于C#语言与ArcGIS Engine组件构建GIS桌面端数据库系统,建立了图形数据库和属性数...

GIS-based Forestry Database System Model and Its Implementation

As the digital forestry’s development and continuously introducing spatial data,the data in forest resource database keeps increasing and it brings problems to the system’s operation efficiency.How to organize data effectively and how to make the query optimization strategy have become the key problems to the forestry database system.This paper uses Zhuji’s forestry resources as our data sources.We use C# programming language and ArcGIS Engine to build GIS database system.It includes graphics database and attribute database.We store data into the forestry geographic information system uniformly and learn about the regional forest resource situation perfectly.
