org.opengis.cite.iso19136.data.spatial.PointTests

public class PointTests
extends DataFixture

Validates the content of a gml:Point element (or any element in its substitution group), which implements the GM_Point class from ISO 19107. A point is defined by a single coordinate tuple.

Method Detail

findPoints

public void findPoints()

A configuration method (BeforeClass) that looks for gml:Point elements in the GML document under test. If none are found all test methods defined in the class will be skipped.

pointHasValidCRS

public void pointHasValidCRS()

[Test] Verifies that a gml:Point element has a valid CRS reference.

Sources

• ISO 19136, cl. 9.10, 10.1.3.2
• ISO 19107, cl. 6.2.2.17 (Coordinate Reference System association)

pointHasValidPosition

public void pointHasValidPosition()

[Test] Verifies the coordinates of a gml:Point. All of the following constraints must be satisfied:

1. length of coordinate tuple = CRS dimension;
2. the point is located within the valid area of the CRS.

Note that the last constraint will detect obvious cases where the axis order is incorrect (e.g. a position expressed in EPSG 4326 as -122.22, 50.55).

• ISO 19107:2003, cl. 6.2.2.10 (coordinateDimension)

createDirectPosition

org.opengis.geometry.DirectPosition createDirectPosition(Element point,
                                                         boolean ignoreThirdDimension)

Creates a DirectPosition object from a gml:Point element. It will have the same CRS as the given point; the reference system may be inherited from a containing geometry (aggregate) or feature.

Parameters:

point - A gml:Point element (or an element in its substitution group).

ignoreThirdDimension - If this flag is true then it will ignore third dimension else it will include all dimension.

Returns:

A DirectPosition holding the coordinates of the original point.

Throws:

IndexOutOfBoundsException - If the length of the coordinate tuple exceeds the dimension of the associated CRS.
