问题

When using a data source based on a Shapefile or GeoJSON file that was imported into SQL Server, visualizations based on the resulting geographies may appear inverted, and the join slower than expected.

环境

  • Tableau Desktop
  • Spatial Joins
  • Shapefiles 
  • GeoJSON 
  • SQL Server

原因

The vertex order convention of Shapefiles is the reverse of the vertex order specified by SQL Server.
