我在 SQL 中有 1000 个 GEOMETRY 形状，我想将它们即时转换为 GEOGRAPHY，但我很难做到这一点。到目前为止，已使用此示例多边形尝试过此代码，但它不会转换，有人可以帮忙吗？为英国创建的多边形的空间索引为 27700。
我看过其他示例，但似乎没有任何效果。

但是，如果我使用 NetTopologySuite 在 C# 中执行此操作，我可以将这些形状点转换为长/纬度。
问题是您的形状不是采用纬度/经度坐标（我们在行业中称为 EPSG:4326 或 WGS:84），这是 SQL Server 在您将几何图形转换（或以其他方式）转换为地理图形时所期望的。
不幸的是，正如这个问题所讨论的，如果没有一些第三部分软件，就不可能重新投影你的几何形状，在这个问题的答案中提出了几种可能性。我会推荐行业领先（且开源）
