【摘要】 本文应用地理信息系统的相关理论与技术,以南京老山林场的空间图形信息为基本数据进行地理信息系统的建立,并利用关系数据模型及可视化技术,使用面向对象的编程语言及GIS二次开发组件Mapobjects完成了老山林场地理信息系统的界面设计和程序设计,实现了系统主要的空间信息管理和属性信息管理功能,基本实现的功能有：(1)显示与制图：系统图形数据库的显示功能是通过Visual Basic6.0编程语言和图形编辑语言MapObject2.4按照林相图和规划设计图的要求进行编译添加的。选择任务栏上专题下拉菜单里面的编辑,用户可通过直观的显示进行统计、查询和修改。(2)双向综合查询：通过空间数据与属性数据之间的查询,实现以下功能：①已知地物的空间位置,查询其属性。即对道路、小班等图形(图元)的查询,获得属性数据。②已知某类地物的属性,查询其主要分布区域,即输入属性查询条件,可以在视图上查询该属性所相应的图元,并在视图上以突起明亮状态显示。(3)统计分析与汇总：用ArcView3.3中基于字段数值的汇总功能Summarize和统计功能Statistics对各小班调查因子分别进行汇总、统计分析,得出基本模块中的专项统计表和直方图。本文所涉及到的关键技术包括有林场空间数据库的建立、VB6.0可视化编程技术的应用以及Mapobjects与编程语言的充分结合。老山林场地理信息系统的建立,能够为该林场进一步实现森林资源信息的全面数字化管理提供开发应用的范例以及良好的数据库支持,并为我国一些林业单位的地理信息系统的建立提供了宝贵的借鉴经验。更多还原

【Abstract】 In this paper, the theory of geographic information systems and technology, to Nanjing, the old forestry basic spatial data, graphical information for the establishment of geographic information systems, and use relational data model and visualization techniques, the use of object-oriented programming language and GIS completed the second development component Map objects old forestry geographic information system interface design and program design, information management. The basic function of the realization of the show are as follows:(1) With drawings:system graphics database shows the function is through Visual Basic6.0 programming languages and graphics editor language MapObject2.4 linxiangtu and planning design in accordance with the requirements of the compiler added. Choose the task bar drop-down menu on the inside of the project, the user can through the intuitive editing statistics and inquires the display and modification. (2) Two-way integrated query:through the spatial data and attribute data, to realize the inquires between the following functions:①the space position, known features its attributes. Inquiry Classes of road, such that the graphics (figure yuan), get attribute data query.②the properties, features some known in its main regional distribution, query that input attribute inquires the views on conditions, can inquire on the properties that the corresponding figure yuan, and in the view to spike bright status display. (3) Statistics analysis and summary:use ArcView3.3 based on field numerical aggregation function to Summarize and statistical functions Statistics classes respectively the investigation factor, summary, statistical analysis, it is concluded that the special TAB and basic modules histogram. In this paper the key technologies involved include forestry spatial database building, VB6.0 visual programming technology and Map objects fully integrated the programming language.Old forest farm of the establishment of geographic information system, to further implement the farm forest resource information management in the over all development and application of digital sample and good database support, and some of China’s forestry unit of the establishment of geographic information systems provide a valuable reference experience.更多还原
