| Unstrukturiertes Gitter mit zusätzlichen SubGrid-Informationen.
| | Ein aus beliebigen Polygonen - Dreiecke und Vierecke - aufgebautes Gitter wird beschrieben. Zusätzlich sind typische Daten des SubGrid vorhanden: SubGrid-Tiefenklassen der Kanten, SubGrid-Tiefenklassen der Polygone, Plot-SubKanten und Plot-SubPolygone. Der Dateityp hierfür ist [[UTRSUB_GRID.DAT|utrsub_grid.dat]]. |
| | Die Speicherung von Daten auf diesem Gitter, z. B. der Tiefe (Bathymetrie), wird an anderer Stelle |
| | beschrieben (siehe [[NetCDF Synoptische Daten im Dreiecksgitter]]). Ebenso werden hier keine Informationen über offene und geschlossene Kanten oder Positionen zum Einsteuern von Randwerten aufgeführt. Es wird ausschließlich |
| | die Struktur (Topologie) des Gitters beschrieben. |
| | |
| | Die Beschreibung wurde vollständig für die ''staggered data'' Positionen ''node'', ''edge'' und ''poly'' gestaltet. |
