Error creating index for table 'MSParcels': WriteConcern detected an error 'Can't extract geo keys from object, malformed geometry?:

{ type: "Polygon", coordinates: 
    [ [ [ -122.118466012, 47.6511409501, 0.0 ],

        [ -122.118466012, 47.6511409501, 0.0 ] ] ] }

Problem is, I'm copying from SQL Server where identical coordinates pass STIsValid

Using C# driver MongoDB.Driver.Builders.IndexKeys.GeoSpatialSpherical

Mongo version 2.4.4

Any advice?

geojson 对 mongodb 无效——它只接受 x,y 而不是 z 坐标（高度）。这是因为它只有二维索引/查询功能。

您需要从 geojson 文档中删除 z 坐标，如下所示：

{ type: "Polygon", coordinates: 
    [ [ [ -122.118466012, 47.6511409501], 
        [ -122.118687874, 47.6508529655], 
        [ -122.118817718, 47.650852731], 
        [ -122.118890754, 47.650852592], 
        [ -122.118891979, 47.651140118], 
        [ -122.118703033, 47.6511404878], 
        [ -122.118466012, 47.6511409501] ] ] }

您的坐标无效。geojson 多边形是具有两个坐标而不是三个坐标的数组数组（额外的 0.0）
