您好，请问是在平面场景还是球面场景呢？平面场景采用的是大坐标，不是经纬度，平面场景中添加图层需要将图层配置文件（config.scp）中的position的xy值设置为unity camera的xy值，把图层位置作为原点；球面场景中地理原点就是经纬度（0，0）点，不用设置，直接通过经纬度放置对象即可，参考博客：https://blog.csdn.net/supermapsupport/article/details/124881355?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522166987718416782427475579%2522%252C%2522scm%2522%253A%252220140713.130102334.pc%255Fblog.%2522%257D&request_id=166987718416782427475579&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~blog~first_rank_ecpm_v1~rank_v31_ecpm-1-124881355-null-null.nonecase&utm_term=unity&spm=1018.2226.3001.4450
