public static final Length DEFAULT_TOLERANCE_LENGTH

Application default tolerance, 0.04 meter.

Method Detail

create

public static SpatialInfo create(CoordSys coordsys)

Create a (cached) SpatialInfo based on a coordinate system.

getCoordSys

public CoordSys getCoordSys()

Get the coordinate system of the geometry.

Returns:

the coordinate system of the geometry

getZUnit

public LinearUnit getZUnit()

Get the linear unit of the z coordinate of the geometry.

This value may be null even if the geometry has z values set. A unitless z value is supported.

Returns:

the linear unit of the z coordinate. May be null.

IGeometry.zSet()

getTolerance

public double getTolerance()

Get the tolerance to use when comparing the coordinates of the geometry.

This value is in the distance unit (either angular or linear) of the coordinate system of this object.

Returns:

the tolerance value to use when comparing coordinates

getToleranceLength

public Length getToleranceLength()

Get the tolerance to use when comparing the coordinates of the geometry. The tolerance is represented as a Length.

Returns:

the tolerance value represented as a Length

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
