| 摘 要： | 在测绘工作中,宗地数据一般为dwg格式,要实现数据入库必须对原数据进行处理,即在原数据中宗地属性的扩展数据存储在宗地内的直线中,要将宗地属性与宗地边界线一起入库并解决其带来的孤岛现象。利用开源数据库Spatialite的空间分析功能和AutoCAD的二次开发语言ObjectARX.Net对该类数据进行了处理,并通过GDAL/ORG库将宗地数据转换为ESRI shp格式,从而实现入库。

| Abstract: | DWG format is generally used in parcel data of surveying and mapping.The original data must be processed in order to be imported into a database.The extended data of parcel attributes in the original data are stored in the straight line of the parcel.Parcel attributes and boundary lines must be imported together into a database to solve the island phenomenon.In this paper,the data of parcel attributes and boundary lines are processed by spatial analysis function of Spatialite which is an open source database and ObjectARX.Net,the secondary development language of AutoCAD,and the parcel data can be changed into ESRI shp file format by GDAL / ORG database,so it can be imported into GIS database. |
