基于D、E级控制网的数据融合技术研究

河南省地籍管理部门,在第一次土地调查、第二次土地调查、城镇地籍初始调查、城镇地籍更新调查、农村集体土地所有权调查、农村集体土地使用权调查等几次大的国字号地籍调查工作中,取得了丰富的地籍调查成果。但是,由于调查成果的时间、坐标基准、比例尺和技术方法存在差异,给统一的信息化地籍管理造成了障碍。对不同时间、不同比例尺、不同坐标系统的地籍数据成果进行统一和融合,是解决这一障碍的方法,同时,对于地籍管理的大数据应用意义重大。

Research on Data Fusion Technology Based on D and E Level Control Network

Cadastral management departments of Henan Province,through a land survey,the second land survey,urban cadastral initial investigation,urban cadastral updating investigation,rural collective land ownership investigation,and the rural collective land use investigation right.Several big national cadastral survey and achieved rich results.However,due to the differences of the survey time,the coordinates of the benchmark,scale and technical methods,for the unified management of information technology has caused obstacles.For different time,different scale,different coordinate system of cadastral data results for unity and integration is a good way to solve this obstacle,while,for cadastral management of large data applications.
