Significance of the File

contains grid data for the numerical model UnTRIM2 (with SubGrid data)

File-Contents (in Catchwords)

  1. static informations:
    • number of vertices;
    • number of edges (geometric edges of a grid);
    • number of polygons (geometric polygons of a grid);
    • number of red polygons;
    • number of polygons at open boundaries;
    • number of internal edges;
    • last edge number with Dirichlet boundary condition (number of edges with flow);
    • mean geographic latitude;
    • EPSG code for coordinate transformation (see EPSG Geodetic Parameter Registry);
    • informative text;
    • number of subpolygons (larger or equal than number of polygons);
    • number of subedges (larger or equal than number of edges with flow).
  2. dynamic data:
    • vertex data (for each vertex):
      • vertex number (informative),
      • x- and y-coordinate, and
      • (optional) vertex depth.
    • polygon data (for each polygon):
      • polygon number (informative),
      • number of vertices (and edges),
      • x- and y-coordinate of the center (meaningful for the computational method),
      • node indices (anti clockwise sorting), and
      • edge indices (anti clockwise sorting).
    • edge data (for each edge):
      • edge number (informative),
      • first node of an edge,
      • second node of an edge,
      • indices of adjacent polygons (0 indicates missing polygons - boundary edge).
    • subpolygon data (for each polygon):
      • polygon number (informative),
      • number of local subpolygons,
      • areas for all local subpolygons (the sum of all subpolygon areas must be less than or equal to the geometric polygon area), and
      • depths for all local subpolygons.
    • subedge data (for each edge):
      • edge number (informative),
      • number of local subedges,
      • lengths of all local subedges (the sum of all subedge lengths must be less than or equal to the geometric edge length), and
      • depths for all local subedges.
