GRASS GIS manual: v.in.adcirc

NAME

v.in.adcirc_grid - Loads ADCIRC fort.14 triangular mesh into a GRASS vector.

KEYWORDS

Import, ADCIRC, vector

SYNOPSIS

v.in.adcirc_grid
v.in.adcirc_grid help
v.in.adcirc_grid [-p] input=name output=name [--overwrite] [--verbose] [--quiet]

Flags:

-p: Load node points instead of mesh lines
--overwrite: Allow output files to overwrite existing files
--verbose: Verbose module output
--quiet: Quiet module output

Parameters:

input=name: Name of input file
output=name: Name for output vector map

DESCRIPTION

This module will import a grid and boundary information file (fort.14) created for the ADCIRC coastal ocean circulation model. The user may choose between importing the mesh grid triangles as lines, or by using the -p flag, importing the grid nodes as points. In both cases 3D coordinates and identifier numbers are preserved.

NOTES

MPI users can import the fort.14 files from the PE0000/ directories to spatially view the sections of the full grid running on each node. (e.g. for determining which SWAN control files to manually adjust)

Depths are converted to negative values during the import.

EXAMPLES

Import the mesh grid as vector lines:

v.in.adcirc_grid input=fort.14 output=mesh_grid

Copy the per-node grid files into the main working directory, then import them individually:

for dir in PE0* ; do
   cp $dir/fort.14 fort.14.$dir
   v.in.adcirc_grid input=fort.14.$dir output=mesh_grid_$dir
done

TODO

Create an attribute database containing node attributes. (boundary nodes, ...)
