农村房地一体化测绘的研究

The Study on Integrated Mapping to Rural Integration of Housing and Land

研究探讨了农村房地一体化测量中边长投影变形与坐标系选择、界址点标志建立、宗地草图绘制问题。通过研究得出如下结论:1)当边长综合投影变形超过规范规定的2.5 cm/km时,可建立两套坐标系,一套为CGCS2000坐标系,另一套为抵偿坐标系,两种坐标系下成果分别供上报数据和本地日常管理使用;2)界址点可以不在实地做标识;3)宗地草图一定要现场绘制,其底图可以多样性,但同一个村应该有同一性质的底图,决不允许用宗地图代替宗地草图。

This research discusses the problems of side length projection deformation and coordinate system selection,establishment of boundary markers,and drawing of parcel sketches in the integrated mapping to rural integration of housing and land.The following conclusions are drawn through the research:1)When the comprehensive projection deformation of the side length exceeds 2.5 cm/km specified in the specification,two sets of coordinate systems can be established,one is the CGCS2000 coordinate system,and the other is the compensation coordinate system.The results of these two coordinate systems are used for reporting data and local daily management.2)The boundary point may not be marked on the spot.3)The sketches of land parcels must be drawn on-site,and the base maps can be diversed,but the same village should be with the base maps of the same nature,and the sketches of land parcels are never allowed to replace the land parcel maps.
