摘要
为满足“省级统筹、市县协同、联动更新”的新型基础测绘要求,湖北省开展了新型基础测绘项目试点工作。试点生产组织模式是建立大比例尺图库一体化的基础地理信息数据库。基于立体航测成图软件,对地理要素进行合理编码,研究了一套集内业采集和编辑入库于一体的三维数据数据采集入库出图方法,获取了试点区域的三维DLG数据。实验证明,图库一体化的数据采集与更新工艺流程不仅保证了图形数据与数据库数据的统一,而且极大地提高了DLG的更新效率和数据质量。
To meet the new basic surveying and mapping requirements of“provincial overall planning,city-county coordination and linkage up-dating”,Hubei Province has carried out the new basic surveying and mapping project pilot work.The pilot production organization mode is to es-tablish a basic geographic information database integrating large scale DLG mapping and database.Based on the three-dimensional aerial map-ping software,this paper reasonably encoded geographic elements and proposed the 3D data acquisition method integrating large scale DLG map-ping and database in one system,and obtained the pilot area three-dimensional DLG data.The experiment shows that the acquisition can not only ensure the unity of terrain graphics and database data,but also greatly improve DLG update efficiency and data quality.
