Element gml:TinType / gml:stopLines
Namespace http://www.opengis.net/gml
Annotations
Stoplines are lines where the local continuity or regularity of the surface is questionable. In the area of these pathologies, triangles intersecting a stopline shall be removed from the tin surface, leaving holes in the surface. If coincidence occurs on surface boundary triangles, the result shall be a change of the surface boundary. Stoplines contains all these pathological segments as a set of line strings.

Annotations
Breaklines are lines of a critical nature to the shape of the surface, representing local ridges, or depressions (such as drainage lines) in the surface. As such their constituent segments must be included in the tin eve if doing so violates the Delauny criterion. Break lines contains these critical segments as a set of line strings.

Annotations
Areas of the surface where data is not sufficiently dense to assure reasonable calculation shall be removed by adding a retention criterion for triangles based on the length of their sides. For many triangle sides exceeding maximum length, the adjacent triangles to that triangle side shall be removed from the surface.

Annotations
The corners of the triangles in the TIN are often referred to as pots. ControlPoint shall contain a set of the GM_Position used as posts for this TIN. Since each TIN contains triangles, there must be at least 3 posts. The order in which these points are given does not affect the surface that is represented. Application schemas may add information based on ordering of control points to facilitate the reconstruction of the TIN from the control points.

Annotations
A tin is a triangulated surface that uses the Delauny algorithm or a similar algorithm complemented with consideration of breaklines, stoplines, and maximum length of triangle sides. These networks satisfy the Delauny's criterion away from the modifications: Fore each triangle in the network, the circle passing through its vertices does not contain, in its interior, the vertex of any other triangle.

Attributes
QName Type Fixed Default Use Annotation
axisLabels gml:NCNameList optional
Ordered list of labels for all the axes of this CRS. The gml:axisAbbrev value should be used for these axis labels, after spaces and forbiddden characters are removed. When the srsName attribute is included, this attribute is optional. When the srsName attribute is omitted, this attribute shall also be omitted.
gid string optional
This attribute is included for backward compatibility with GML 2 and is deprecated with GML 3. This identifer is superceded by "gml:id" inherited from AbstractGMLType. The attribute "gid" should not be used anymore and may be deleted in future versions of GML without further notice.
gml:id ID optional
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.
srsDimension positiveInteger optional
The "srsDimension" is the length of coordinate sequence (the number of entries in the list). This dimension is specified by the coordinate reference system. When the srsName attribute is omitted, this attribute shall be omitted.
srsName anyURI optional
In general this reference points to a CRS instance of gml:CoordinateReferenceSystemType (see coordinateReferenceSystems.xsd). For well known references it is not required that the CRS description exists at the location the URI points to. If no srsName attribute is given, the CRS must be specified as part of the larger context this geometry element is part of, e.g. a geometric element like point, curve, etc. It is expected that this attribute will be specified at the direct position level only in rare cases.
uomLabels gml:NCNameList optional
Ordered list of unit of measure (uom) labels for all the axes of this CRS. The value of the string in the gml:catalogSymbol should be used for this uom labels, after spaces and forbiddden characters are removed. When the axisLabels attribute is included, this attribute shall also be included. When the axisLabels attribute is omitted, this attribute shall also be omitted.
