摘 要: | 在分析相关文件在土地调查图斑椭球面面积计算中存在问题的基础上,通过多个模拟算例,推证了直接使用相关规定计算椭球面面积公式的必要条件:土地利用现状数字线划专题图上的平面多边形图斑各边必须按不超过70m点距实施插点预处理。最后以浙江省陆域面积计算实例验证了课题组所提必要条件的可靠性。 |
关 键 词: | 地籍测量;土地调查;面积计算;高斯平面面积;椭球面面积 |

Abstract: | The existing problem of map spot area calculation on ellipsoid surface in relevant regulations is analyzed in this paper. On the basis of the analysis, it’s verified that the essential condition to use the relevant regulations directly is that points on digital line thematic graph of land use status must be inserted on each side of polygon with distance between adjacent points not over 70 m. In order to verify reliability of the above condition, an example of area calculation of Zhejiang province is introduced. |
Key words: | cadastral survey; land survey; area calculation; Guass plane area; ellipsoid surface area |
