Verwendung

Mit diesem Werkzeug wird das Eingabe-TIN geändert. Sie haben die Möglichkeit, das Werkzeug TIN kopieren zum Verwalten einer Sicherung zu verwenden, wenn Sie eine nicht geänderte Version des Quell-TIN beibehalten möchten.
Anhand des Oberflächen-Feature-Typs wird definiert, wie die Eingabe-Features zur Definition der triangulierten Oberfläche beitragen.
- Punkt-Features können als Massenpunkte festgelegt werden, die Datenknoten bereitstellen, deren Z-Werte in der Triangulation der Oberfläche verwendet werden.
- Linien-Features können als Massenpunkte und Bruchkanten festgelegt werden, die Positionen an einer Oberfläche mit linearen Unterbrechungen in der Neigung darstellen, z. B. Bergkämme, Küstenlinien, Straßenbelagskanten, Gebäudegrundrisse usw.
- Polygon-Features können auch als Massenpunkte und Bruchkanten zusammen mit Clip-Features festgelegt werden, die die Datenfläche definieren, Features ersetzen, die Regionen mit konstanten Z-Werten (z. B. Gewässer) definieren, sowie Features löschen, die innere Flächen angeben, in denen keine Daten vorhanden sind.
Wenn genügend Arbeitsspeicher vorhanden ist, kann mit diesem Werkzeug ein TIN mit Millionen von Punkten erstellt werden. Durch das Begrenzen der Anzahl der TIN-Knoten auf einen Wert unter 6 Millionen werden eine reaktionsschnelle Darstellungs-Performance und allgemeine Benutzerfreundlichkeit gewährleistet. Wenn eine größere TIN-Oberfläche benötigt wird, sollten Sie ein Terrain-Dataset verwenden. Das Terrain-Dataset bietet eine TIN-Oberfläche mit mehreren Auflösungen, die viel größere Sammlungen von Quellenmessungen unterstützen kann.

Spalten der Wertetabelle: Input Features—The features that will be added to the TIN. Height Field—The field from the input's attribute table that will provide the elevation for its features. The z- or m-values in the `Shape` field can be used along with any numeric field. Choosing the `<None>` option will result in the feature's elevation being interpolated from its surrounding 3D measurements. Tag Field—A numeric attribute will be assigned to the TIN's data elements using values obtained from an integer field in the input feature's attribute table. Type—The input feature's role in defining the TIN surface. The available options depend on the geometry of the input features. For line- and polygon-based surface feature types, the hard and soft designations for the surface feature type impact the way the line or polygon boundary is handled when interpolating a raster surface from the TIN dataset when using natural neighbor interpolation. A hard surface feature type represents a border with a sharp discontinuity in elevation, such as the edge of a cliff, a wall, or a curb on the side of the road. A soft surface feature type represents a border where the elevation is more smoothly defined. Mass Points—Elevation measurements will be incorporated as TIN nodes. Hard Line—Breakline features will define linear discontinuities in the TIN. Soft Line—Breakline features will define linear discontinuities in the TIN. Hard Clip—Polygon features will define the data area of the TIN surface. Soft Clip—Polygon features will define the data area of the TIN surface. Hard Erase—Polygon features will define interior voids in the data. Soft Erase—Polygon features will define interior voids in the data. Hard Replace—Polygon features will define areas of constant height. Soft Replace—Polygon features will define areas of constant height. Hard Value Fill—Integer attributes will be assigned to nodes and triangle faces. Soft Value Fill—Integer attributes will be assigned to nodes and triangle faces. Use Z—Specifies whether z- or m-values will be used when the `SHAPE` field is specified as the height source. Specifying `True` indicates that z-values will be used; specifying `False` indicates that m-values will be used.	Value Table
Constrained Delaunay (Optional)	Gibt die Triangulationstechnik an, die entlang der Bruchkanten des TIN angewendet werden soll. Aktiviert—The TIN will use constrained Delaunay triangulation, which will add each segment as a single edge. Delaunay triangulation rules are honored everywhere except along breaklines, which will not be densified. Deaktiviert—The TIN will use Delaunay conforming triangulation, which may densify each segment of the breaklines to produce multiple triangle edges. This is the default.	Boolean
