安徽省测量坐标系转换服务

通过分析近20年安徽省内各种不同工程类型项目的基础测绘数据，构建精化大地水准面模型和七参数转换模型。基于该模型实现了用户不同项目、不同时期成果数据（包括不限于测量点坐标、地形图、基于地形图的勘察设计图）的平面、高程坐标系转换及数据格式转换。

By analyzing basic surveying and mapping data from various engineering projects in Anhui Province over the past 20 years, refined geoid models and seven-parameter transformation models were constructed. Based on these models, conversions of planar and elevation coordinate systems as well as data formats were realized for survey products from different projects and time periods of users, including but not limited to survey point coordinates, topographic maps, and survey and design drawings derived from topographic maps.
