在MSSQL上检查有效性不会捕获超过地球一半的多边形吗？我认为地理是一项要求。采矿场地很大。对可视化工具有什么建议吗？检查完这些区域后，我不得不用ReorientObject（）翻转大部分区域。这样做的副作用是将所有multiplogon定义都转换为空集合。他们都知道区域接近51e14极限。娱乐的想法，所以他们将是正确的方法？将它们分开单独处理？大于地球一半的多边形是有效的，SQL Server有办法处理它们（因为某些版本）。不幸的是，要允许它们，它必须遵循方向规则——这在shapefile中不存在，因此它们可能会被错误加载。我不知道如何可靠地将shapefile加载到SQL Server。我很了解BigQuery，它使用相同的定向规则，但BigQuery可以加载GeoJson，而我认为SQL Server不支持这一点。谢谢你的帮助。在MSSQL上检查有效性不会捕获超过地球一半的多边形吗？我认为地理是一项要求。采矿场地很大。对可视化工具有什么建议吗？检查完这些区域后，我不得不用ReorientObject（）翻转大部分区域。这样做的副作用是将所有multiplogon定义都转换为空集合。他们都知道区域接近51e14极限。娱乐的想法，所以他们将是正确的方法？将它们分开单独处理？大于地球一半的多边形是有效的，SQL Server有办法处理它们（因为某些版本）。不幸的是，要允许它们，它必须遵循方向规则——这在shapefile中不存在，因此它们可能会被错误加载。我不知道如何可靠地将shapefile加载到SQL Server。我很了解BigQuery，它使用相同的定向规则，但BigQuery可以加载GeoJson，而我认为SQL Server不支持这一点。谢谢你的帮助。
