Well-Known Text representation, the Point geography static methods accepts as parameters the Latitude and Longitude coordinates of the point in that order. Unlike the STGeomFromText and STPointFromText geography static methods, which accepts as parameter the point coordinates in the Open Geospatial Consortium (OGC) The geography::Point method constructs a geography instance representing a POINT instance from the latitude and longitude values. Yet another way of creating a geography POINT spatial data object is with the use of the geography::Point extended static geography method.

System.FormatException: 24142: Expected 'POINT' at position 1. If you try to pass any other spatial data object to the STPointFromText aside fromĪ POINT, you will get the following error message: Msg 6522, Level 16, State 1, Line 3 MULTIPOINT, MULTIPOLYGON, MULTILINESTRING and GEOMETRYCOLLECTION). Unlike the STPointFromText method, which only accepts a POINT, the STGeomFromText can accept any of the seven spatial data objects (POINT, POLYGON, LINESTRING, SET = geography::STGeomFromText('POINT(' + CAST( AS VARCHAR(20)) + ' ' + OGC static method, the STGeomFromText returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation. System.FormatException: 24201: Latitude values must be between -90 and 90 degrees.Īnother way of creating a geography POINT is with the use of the STGeomFromText OGC static method. NET Framework error occurred during execution of user-defined routine or aggregate 'geography': Message particularly for the Sydney Opera House landmark record: Msg 6522, Level 16, State 1, Line 1Ī. If the latitude and longitude were accidentally interchanged in the parameter for the STPointFromText, you may get the following error Similarly, latitude is defined as the distance from the equator along the Y-axis. Longitude is defined as the distance from the prime meridian along the x-axis (or theĮquator). Think of the equator of the earthĪs the x-axis while the prime meridian is the Y-axis. You may be wondering why the X-coordinate is the Longitude while the Y-coordinate is the Latitude. Specified by Lat/Long but between these two, the X is the Longitude while the Y is the Latitude. Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation, the format is (x, y).

SET = geography::STPointFromText('POINT(' + CAST( AS VARCHAR(20)) + ' ' +ĬAST( AS VARCHAR(20)) + ')', 4326)Īs you can see from this UPDATE statement, the longitude is specified first before the latitude. STPointFromText returns a geography instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation. To convert the latitude and longitude coordinates to a geography point, we will use the StPointFromText function. This canĮasily be done by the ALTER TABLE statement and we will use the GEOGRAPHY data type for the new column. The first thing to do is to add the new column where we will store the geography point.

Of these landmarks were taken from Google maps and not from Microsoft's Virtual Earth (or Bing Maps).) CREATE TABLE. (Note: The latitude and longitude coordinates To take advantage of SQL Server 2008's new geography data type. Let's say we have a table of famous international geographic landmarks where we store its latitude and longitude coordinates and we want From these spatial data objects, we will be using the Point. MultiLineString, Polygon, MultiPolygon and Geometr圜ollection. The GEOGRAPHY data type supports seven spatial data objects that you can create and work with, namely Point, MultiPoint, LineString, ThisĪrticle will show the different ways of converting the latitude and longitude coordinates of geography locations into a geography POINT. In SQL Server 2008, particularly the GEOGRAPHY data type, this can now be stored as points in a single column stored as a spatial data object. With the introduction of spatial data types Prior to SQL Server 2008, geography locations such as bank branches, restaurant locations and household locations,Īre usually stored as latitude and longitude coordinates in two separate columns.
