摘要
针对土地开发整理过程中不同比例尺数据转换后面积计算的问题,该文依据微结构不规则图形具有的周长、面积关系,将分形理论引入到不同比例尺数据相互转换后的面积计算中,探讨具有不同比例尺数据的土地整理项目面积计算方法,得到一种基于分形理论的面积计算方法。试验证明,该算法具有运算速度快、算法简单、计算结果合理等优点。
In the process of the land consolidation, there will always be on the problem of areas calculation of graphic converted between different scales. How to calculate the areas accurately and efficiently is very important for land planning and design,the control of total investment and allocating fund. Aimed at the problem of area problem,based on the microstructure with irregular graph of perimeter,area relations in the Literature [7],the fractal theory was introduced into post-conversion area calculation between different scale map in this paper. The area calculation method of different scales data of land consolidation was discussed,and a kind of area calculation method based on the fractal theory was gotten. The experiment proved this algorithm is simply, faster and the calculation results are reasonable.
