Schema documentation for component diggs:axisRef

Reference to the axis being defined. Should reference an axis defined in the CartesianCS of the parent LocalCartesianCRS. Typically references the gml:id of a gml:CoordinateSystemAxis element (e.g., "X", "Y", "Z", "easting", "northing", "elevation", "station", "offset").

The ordinal position of this axis in the Cartesian coordinate system definition (1 for the first axis, 2 for the second axis, etc.). This ensures correct matching between axes in the CS definition and their spatial extents, particularly important when the axis order is not alphabetical.

The spatial direction and extent of this axis, expressed as a LinearExtent in the spatial coordinate reference system of the . The start point of the LinearExtent typically corresponds to the origin location of the parent CRS, and the end point indicates the direction and length of the axis in spatial coordinates. The vector from start to end defines the positive direction of the axis. If omitted, the property directionVector must be used.

xlink:actuate

restriction of string

optional

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

xlink:show

restriction of string

optional

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 context
replace - load the resource in the same window, frame, pane, or 
          other presentation context
embed - load ending resource in place of the presentation of the 
        starting resource
other - behavior is unconstrained; examine other markup in the 
        link for hints 
none - behavior is unconstrained

Optional normalized direction vector (unit vector) for this axis in spatial coordinates. This provides an alternative or supplementary method to specify axis direction beyond the LinearExtent. When both are provided, they should be consistent with each other. The vector components correspond to the spatial CRS axes (typically X, Y, Z or Easting, Northing, Elevation). If omitted, location must be used.

Type definition for specifying the spatial extent and direction of a single axis in a local coordinate system. This information enables the axis to be spatially positioned and oriented in a spatial coordinate reference system, supporting coordinate transformation calculations.

Database handle for the object. It is of XML type ID, so is constrained to be unique in the XML document within which it occurs. An external identifier for the object in the form of a URI may be constructed using standard XML and XPointer methods. This is done by concatenating the URI for the document, a fragment separator, and the value of the id attribute.
