Buat polyline geografi dari titik di T-SQL

coba ini :(catatan :pengurutan titik penting agar garis dihasilkan dengan benar.)

DECLARE @BuildString NVARCHAR(MAX)
SELECT @BuildString = COALESCE(@BuildString + ',', '') + CAST([Longitude] AS NVARCHAR(50)) + ' ' + CAST([Latitude] AS NVARCHAR(50))
FROM dbo.LongAndLats
ORDER BY SortOrder             

SET @BuildString = 'LINESTRING(' + @BuildString + ')';   
DECLARE @LineFromPoints geography = geography::STLineFromText(@BuildString, 4326);
SELECT @LineFromPoints
