摘要
平面坐标系统服务于地理信息系统、大比例尺地图、大型工程建设等多种应用,美国的州平面坐标系统历经SPCS27、SPCS83到最新的SPCS2022,形成了一套完善的技术体系,按照统一的标准编设带名带号,综合考虑各州的地形特征、行政区划、人口分布等多种因素,将长度变形控制在一定限度内。为了保持现势性,SPCS2022与国家空间参考系统中的板块参考框架关联。梳理美国州平面坐标系统的发展历程,分析SPCS2022的建立过程和主要特点,在设计思想和技术方法上为建立独立平面坐标系提出启示和建议。
The plane coordinate system serves a variety of applications such as geographic information system,large-scale mapping and engineering.The State Plane Coordinate System in the United States,from SPCS27,SPCS83 to the latest SPCS2022,has formed a well-developed technical system.In order to limit the length deformation within a certain range,all projection zones,whose names and numbers according to the unified standards,are determined comprehensively according to the topographic characteristics,administrative divisions,population distribution,etc.The projection zones are connected with the tectonic plate reference frames of the National Spatial Reference System so as to maintain the current status of the results.By sorting out the development history of SPCS and analyzing the establishment process and main characteristics of SPCS2022,the inspirations and suggestions about design concept and technical methods for the establishment of an independent plane coordinate system are put forward.
