【摘要】 土地利用数据库是反映全国土地资源空间分布状况的、大尺度数据,是从国家层次进行可持续宏观决策研究的重要依据,是实现土地管理信息化,全面管理土地资源重要的数据平台。本文针对土地利用数据库结构的特点和需求,利用Geoimager、AutoCAD、Arc/Info、ArcGIS和MAPGIS相结合的方法对土地利用数据库进行研究和设计。论文完成的主要工作如下:(1)对土地利用数据库的结构特点、应用需求进行了深入的分析和研究,阐述了土地利用数据库的数据采集、处理和数据库整个建设过程。(2)对Geoimager、AutoCAD、Arc/Info、ArcGIS和MAPGIS等多种技术相结合的建库方法展开了讨论。利用AutoCAD和DMAPS2002进行数据采集、利用Arc/Info、ARCGIS提供的语言编写的工具对数据进行处理,利用MAPGIS进行建库。(3)对在土地利用数据库设计和建设过程中遇到的一些关键技术和问题进行了研究,主要包括:不同GIS平台之间的数据格式转换方法;如何消除人为产生的错误问题;以及图形接边、图形拼接、面积检核、狭长图斑识别等问题。(4)在上述分析研究的基础上,设计出基于MAPGIS的土地利用数据库,详细描述了整个建库的流程:数据采集、数据处理、数据建库。该土地利用数据库已完成设计和调试,现已成功地运用在安徽省宿州市埇桥区、马鞍山市区、当涂县、芜湖县、郎溪县、灵璧县、界首市、萧县、太和县等1:1万土地利用数据库建库项目中。更多还原

【Abstract】 As a kind of the large-scale data for reflecting the national spatial distribution of land resources,Land use database is an important basis for government’s macro decision-making on national sustainable development and an important data platform for realizing the informationization of land management and for roundly managing land resources.Aimed at the structures and characteristics,this thesis researched and designed the land-use database based on the combination of such tools as Geoimager,AutoCAD,Arc / Info,ArcGIS and MAPGIS.The main works of the thesis are as follows:(1) Characteristics and the application needs of the land use database were analyzed and researched in depth,and the data collection,processing of land use database or even the entire construction process of land use database had been expatiated.(2) By the combination of Geoimager,AutoCAD,Arc / Info,ArcGIS and MAPGIS and other technology,the building methods were discussed.IN the method mentioned in this thesis,DMAPS2002 and AutoCAD were used for data collection,the language and tools provided by Arc / Info,ARCGIS were used for the data processing,MAPGIS were used for database construction.(3) Encountered in land use database designing and construction,some core technologies and research issues were analyzed,including the conversion method of GIS platform between different data format;how to eliminate man-made errors; and any other problems such as graphics Edge matching,graphics splicing,area checking,strip map speckle identification.(4) Based on the above-mentioned analysis,the design of land use database was made up on MAPGIS platform.Furthermore the entire process of land use database was described in detail,including data collection,data processing,database construction.At present,the designing and debugging of the land use database has completed, which has been used successfully for 1:1 million land use database building projects on such counties and districts in Anhui Province as:Yongqiao District of Suzhou City,Ma’anshan City,Dangtu County,Wuhu County,LangXi County, Lingbi County,Jieshou City,Xiaoxian County,Taihe County.更多还原
