宗地面积量算的误差分析

在阐述面积量算误差的同时,重点分析了用坐标法计算面积时宗地形状对面积精度的影响.据研究,宗地面积量算的方法不同,其精度就有所不同.在采用解析法中的坐标法量算面积时,宗地面积的精度不但和界址点的精度有关,还和宗地的形状有关.在面积相同,界址点个数相同,界址点点位中误差相同的情况下,宗地为正多边形时其面积量算的中误差最小.

Error Analysis of Parcel Area Measuring

In cadastral survey and management, the area amount can be regarded as the essential content, mentioning its precision, because methods to adopt are different, the precision is different to some extent. While while taking about the precision of calculating of area amount of coordinate law in the analytic method, everybody knows its precision conciliates the precision clicked in location and has something to do, some people will ignore a question, that is while regarding form of as the area with the law amount of coordinate, the precision of the area of a case of ground is still involved in one, in the same area, solve some number in the location the samly, hit under situation with the same error in some positi in the circle location, case for area their hit error to be minimum at the regular polygon. This text while calculating the error in amount of area explains, analyzes with coordinate law cases of topographical form impact on precision of area at the area of calculating especially.
