| 摘 要： | 针对农村地籍调查中的长度投影变形问题,对长度变形不超过2.5 cm/km的规定提出了质疑,探讨出了通过任意带投影来减少农村地籍调查中的长度投影变形,并同时简化了长度投影变形的计算公式,达到了合理、高效控制高斯投影长度变形影响的目的,既满足了数据质量要求又便于国土资源数据的统一管理。

| Abstract: | For the length projection deformation of rural cadastral investigation,the paper questioned the rules of length deformation less than 2.5cm/km,discussed to reduce the length of the projection of rural cadastral investigation in deformation by arbitrary projection,and simplified formula for Length Projection deformation,reached a reasonable and efficient control effect of Gauss projection length deformation,not only meet the requirements of data quality,but also facilitate unified management of land and resources data. |
