Each row of the SYSSPATIALREFERENCESYSTEM system view describes an SRS defined in the database. The underlying system table for this view is ISYSSPATIALREFERENCESYSTEM.
This view offers slightly different amount of information than the ST_SPATIAL_REFERENCE_SYSTEMS system view.
Column name  Data type  Description  

object_id  UNSIGNED BIGINT  For system use only.  
owner  UNSIGNED INT  The owner of the SRS.  
srs_name  CHAR(128)  The name of the SRS.  
srs_id  INT  The numeric identifier (SRID) for the spatial reference system.  
round_earth  CHAR(1)  Whether the SRS type is ROUND EARTH (Y) or PLANAR (N).  
axis_order  CHAR(12)  Describes how the database server interprets points with regards to latitude and longitude (for example when using the ST_Lat and ST_Long methods). For nongeographic spatial reference systems, the axis order is x/y/z/m. For geographic spatial reference systems, the default axis order is long/lat/z/m; lat/long/z/m is also supported.  
snap_to_grid  DOUBLE  Defines the size of the grid SQL Anywhere uses when performing calculations.  
tolerance  DOUBLE  Defines the precision to use when comparing points.  
semi_major_axis  DOUBLE  Distance from center of the ellipsoid to the equator for a ROUND EARTH SRS.  
semi_minor_axis  DOUBLE  Distance from center of the ellipsoid to the poles for a ROUND EARTH SRS.  
inv_flattening  DOUBLE 
The inverse flattening used for the ellipsoid in a ROUND EARTH SRS. Inverse flattening (f) is a mathematical value that defines the degree of squashing of the pole of a spheroid towards its equator. The value ranges from no flattening (a perfect circle) to complete flattening (a straight line). Inverse flattening is the value of 1/f, as follows:


min_x  DOUBLE  The minimum x value allowed in coordinates.  
max_x  DOUBLE  The maximum x value allowed in coordinates.  
min_y  DOUBLE  The minimum y value allowed in coordinates.  
max_y  DOUBLE  The maximum y value allowed in coordinates.  
min_z  DOUBLE  The minimum z value allowed in coordinates.  
max_z  DOUBLE  The maximum z value allowed in coordinates.  
min_m  DOUBLE  The minimum m value allowed in coordinates.  
max_m  DOUBLE  The maximum m value allowed in coordinates.  
organization  LONG VARCHAR  The name of the organization that created the coordinate system used by the spatial reference system.  
organization_coordsys_id  INT  The ID given to the coordinate system by the organization that created it.  
srs_type  CHAR(11) 
The type of SRS as defined by the SQL/MM standard. Values can be one of:
If srs_type is empty, the type is unspecified. 

linear_unit_of_measure  UNSIGNED BIGINT  The linear unit of measure used by the spatial reference system.  
angular_unit_of_measure  UNSIGNED BIGINT  The angular unit of measure used by the spatial reference system.  
count_in_use  UNSIGNED BIGINT  For internal use only.  
polygon_format  LONG VARCHAR  The orientation of the rings in a polygon. One of CounterClockwise, ClockWise, or EvenOdd.  
storage_format  LONG VARCHAR  Whether the data is stored in normalized format (Internal), unnormalized format (Original), or both (Mixed).  
definition  LONG VARCHAR  The WKT definition of the spatial reference system in the format defined by the OGC standard.  
transform_definition  LONG VARCHAR  Transform definition settings for use when transforming data from this SRS to another.
