The spatial location of the origin (0,0,0) point of this localengineering CRS, expressed in a recognized spatial coordinatereference system. This point serves as the anchor for transforminglocal engineering coordinates to the target spatial coordinates.
The 'actuate' attribute is used to communicate the desired timing of traversal from the starting resource to the ending resource; it's value should be treated as follows:onLoad - traverse to the ending resource immediately on loading the starting resource onRequest - traverse from the starting resource to the ending resource only on a post-loading event triggered for this purpose other - behavior is unconstrained; examine other markup in link for hints none - behavior is unconstrained
The 'show' attribute is used to communicate the desired presentation of the ending resource on traversal from the starting resource; it's value should be treated as follows: new - load ending resource in a new window, frame, pane, or other presentation contextreplace - load the resource in the same window, frame, pane, or other presentation contextembed - load ending resource in place of the presentation of the starting resourceother - behavior is unconstrained; examine other markup in the link for hints none - behavior is unconstrained
Spatial extent and direction for each axis defined in theCartesian coordinate system. There should be one axisLocationelement for each axis in the coordinate system. The ordershould match the axis order in the Cartesian CS definition.
Identifier for the mathematical method to be used for coordinatetransformation between this local engineering CRS and spatialcoordinates. Examples include: "affine", "helmert", "direct-linear-referencing", "polynomial", etc.
Rotation angle(s) for orienting the local coordinate systemaxes relative to the spatial coordinate system. For 2D systems,one rotation angle is specified (rotation about the verticalaxis). For 3D systems, up to three rotation angles may bespecified (e.g., Euler angles or rotations about X, Y, and Z axes).The interpretation of multiple angles depends on the specifiedtransformationMethod.
Uniform scale factor applied to the local coordinate systemrelative to the spatial coordinate system. Default is 1.0(no scaling). Values greater than 1.0 indicate that localengineering coordinates represent larger distances than thecorresponding spatial coordinates. Values less than 1.0 indicatethat local engineering coordinates represent smaller distances.
Estimated accuracy of coordinate transformation between thislocal CRS and spatial coordinates. Expressed as a lineardistance uncertainty (e.g., in meters or feet). This valuerepresents the expected positional error when transformingcoordinates between the two systems.
Type definition for a spatially-defined local Cartesian coordinate referencesystem. This type includes the standard CRS components (coordinate system,datum) plus additional spatial positioning elements (origin location, axislocations, transformation parameters) that enable coordinate transformationsbetween the local CRS and spatial coordinate reference systems.
