Aus BAWiki
Kurze Beschreibung
Synoptische Daten an Einzelpositionen.
Inhalt der Datei
An anderer Stelle beschriebene Inhalte
- NetCDF Dreiecksgitter: Koordinaten, Topologie und Koordinatentransformation;
- NetCDF Zeitkoordinate: Koordinatenvariable time;
- NetCDF Vertikalkoordinate: Vertikalkoordinate depth oder height:
- node_depth : Vertikalkoordinate für tiefenstrukturierte Daten an Knoten;
- edge_depth : Vertikalkoordinate für tiefenstrukturierte Daten an Kanten;
- poly_depth : Vertikalkoordinate für tiefenstrukturierte Daten an Polygonen.
Bemerkung: Es werden drei verschiedene Vertikalkoordinaten benötigt, da in jedem Attribut formula_terms verschiedene Variablen für Wasserstand und Boden eingesetzt werden müssen.
Dimensionen
Zu den oben festgelegten Dimensionen kommen noch hinzu:
- dimensions:
