haleĀ»studio supports MsSQL Server database (tested version 2012 and 2014) import like generic Database import based on JDBC. Thus has the same limitations.
haleĀ»studio supports both geometry and geography spatial data types of MsSQL Server but there are some limitations on curved spatial data objects.
All the curved spatial data objects like CurvePolygon, CircularString, CompoundCurve are first interpolate to the Polygon, LineString and LineString respectively. We want to provide all the spatial data types support. However, within its limits to curved spatial data objects it is functional and may be useful to you.
