openflows flood软件在加载地形xyz数据的时候,坐标系设置里面没有更新最新的中国CGCS2000的坐标系,这个地方可以添加自定义坐标系么
另外,国家已经硬性规定测绘要求用统一的CGCS2000,软件里面不配置这个坐标系,后续的坐标对应 应该没法做吧

北京54和国家2000应该不一致吧。这样不会有偏差么
Hello,
You can find more information in the article regarding Coordinate systems and projections in OpenFlows FLOOD.
The proj4 string to the conversion in your case should be: +proj=longlat +ellps=GRS80 +no_defs
Please let me know if it works.
Kind regards,Luis
