Research on Multi-Level Iterative Coordinate Transformation Partitioning Method Based on K-means
Different from traditional coordinate transformation,large-area coordinate transformation usually adopts the method of partition transformation to ensure the precision,and different partition strategies have great influence on the final transformation precision.Therefore,it is of great significance to study the method of large area coordinate transformation.Based on the analysis of the characteristics of large area coordinate transformation,the applicability of K-means algorithm is discussed in this paper.A multi-level iterative partitioned coordinate transformation method based on K-means is proposed and the coordinate transformation program is programmed.The feasibility of the method is verified by an example,which not only adapts to the situation of different area and coordinate point distribution,but also improves the precision of coordinate transformation.
