摘要
随着2000国家坐标系的推广使用,地方坐标系在城市基础测绘中的弃留问题困扰着业内人士。以厦门地区为例,基于国家及地方坐标系统开展的实地测试与验证表明,从施测便利性来看,城市基础测绘的坐标系统不宜选用2000国家坐标系,而宜基于地方坐标系。地方坐标系有其存在的合理性和必要性。
With the popularization and use of the 2000 national coordinate system,the abandonment or reservation of the local coordinate system in urban basic surveying and mapping has troubled the professionals.Taking Xiamen as an example,field tests and verification based on national and local coordinate systems show that,from the point of convenience of surveying,the 2000 national coordinate system is not suitable for urban basic surveying and mapping,conversely,local coordinate system is much more suitable.Local coordinate systems has its rationality and necessity of existence.
