Spatial GeoJSON Functions options , if given, describes how to handle GeoJSON documents that contain geometries with coordinate dimensions higher than 2. The following table shows the permitted  options  values. options  values of 2, 3, and 4 currently produce the same effect. If geometries with coordinate dimensions higher than 2 are supported in the future, you can expect these values to produce different effects. The  srid  argument, if given, must be a 32-bit unsigned integer. If not given, the geometry return value has an SRID of 4326. If  srid  refers to an undefined spatial reference system (SRS), an  ER_SRS_NOT_FOUND  error occurs. For geographic SRS geometry arguments, if any argument has a longitude or latitude that is out of range, an error occurs: Ranges shown are in degrees. If an SRS uses another unit, the range uses the corresponding values in its unit. The exact range limits deviate slightly due to floating-point arithmetic. GeoJSON geometry, feature, and feature collection objects may have a  crs  property. The parsing function parses named CRS URNs in the  urn:ogc:def:crs:EPSG:: srid  and  EPSG: srid namespaces, but not CRSs given as link objects. Also,  urn:ogc:def:crs:OGC:1.3:CRS84  is recognized as SRID 4326. If an object has a CRS that is not understood, an error occurs, with the exception that if the optional  srid  argument is given, any CRS is ignored even if it is invalid. If a  crs  member that specifies an SRID different from the top-level object SRID is found at a lower level of the GeoJSON document, an  ER_INVALID_GEOJSON_CRS_NOT_TOP_LEVEL  error occurs. As specified in the GeoJSON specification, parsing is case-sensitive for the  type  member of the GeoJSON input ( Point ,  LineString , and so forth). The specification is silent regarding case sensitivity for other parsing, which in MySQL is not case-sensitive. This example shows the parsing result for a simple GeoJSON object. Observe that the order of coordinates depends on the SRID used. 2336 Option Value Meaning 1 Reject the document and produce an error. This is the default if  options  is not specified. 2, 3, 4 Accept the document and strip off the coordinates for higher coordinate dimensions. • If a longitude value is not in the range ( − 180, 180], an  ER_LONGITUDE_OUT_OF_RANGE  error occurs. • If a latitude value is not in the range [ − 90, 90], an  ER_LATITUDE_OUT_OF_RANGE  error occurs. mysql>  SET @json = ’{ "type": "Point", "coordinates": [102.0, 0.0]}’; mysql>  SELECT ST_AsText(ST_GeomFromGeoJSON(@json)); +--------------------------------------+ | ST_AsText(ST_GeomFromGeoJSON(@json)) | +--------------------------------------+ | POINT(0 102) | +--------------------------------------+ mysql>  SELECT ST_SRID(ST_GeomFromGeoJSON(@json)); +------------------------------------+ | ST_SRID(ST_GeomFromGeoJSON(@json)) | +------------------------------------+ | 4326 |
