Method Detail

getType

public abstract CoordSysType getType()

Get the type of this coordinate system.

Returns:

The type of this coordinate system.

getDisplayName

public String getDisplayName(Locale locale)

Get the display name for this coordinate system.

Parameters:

locale - The locale of the display name to retrieve.

Returns:

The display name for this coordinate system. May be null.

getCodes

public CodeSet getCodes()

Get the codes for this coordinate system.

Returns:

The codes for this coordinate system.

getAffineTransform

public com.mapinfo.midev.geometry.AffineTransform getAffineTransform()

Get the affine transform for the coordinate system.

Returns:

The affine transform for the coordinate system.

getMBR

public abstract com.mapinfo.midev.util.DoubleRect getMBR()

Get the minimum bounding rectangle of this coordinate system. The unit of measure is that of the coordinate system.

Returns:

The minimum bounding rectangle of this coordinate system.

equivalent

public boolean equivalent(CoordSys coordSys)

Determine whether or not two coordinate systems are equivalent mathematically. tTwo coordinate systems may have different names or identifiers but be mathematically equivalent.

Returns:

true if the two coordinate systems are mathematically equivalent.

createCoordTransform

public CoordTransform createCoordTransform(CoordSys destCoordSys)

Create a new transform from this coordinate system to the specified coordinate system.
