makegrid.sh

use makegrid to create a mesh file for cvms4 testing

We have defined two regions that we want to query, and a series of depths. The makegrid.sh script list embedded configuration values. Below are the values used for this exercise

Grid 1:

this is 10m resolution at depths from 80 to 110

34.5 -118.5 33.5 -117.5

HOR_SPACING=0.0001 VERT_SPACING=5 MIN_DEPTH=80 MAX_DEPTH=110 MIN_LON=-118.5 MAX_LON=-117.5 MIN_LAT=33.5 MAX_LAT=34.5

Word count from the output file is:

Grid 2

35.5 -117.5 34.4 -116.5

HOR_SPACING=0.0001 VERT_SPACING=5 MIN_DEPTH=80 MAX_DEPTH=110 MIN_LON=-117.5 MAX_LON=-116.5 MIN_LAT=34.5 MAX_LAT=35.5

makegrid.sh

[ucvm@91e02b10e48d utilities]$ more makegrid.sh #!/bin/sh

Creates and ASCII grid file with

3272481 mesh points and writes it to

file grd.out

HOR_SPACING=0.1 VERT_SPACING=250 MIN_DEPTH=0 MAX_DEPTH=20000 MIN_LON=-130.0 MAX_LON=-110.0 MIN_LAT=26.0 MAX_LAT=46.0

rm -f out.grd

echo "Generating grid"

for z in seq ${MIN_DEPTH} ${VERT_SPACING} ${MAX_DEPTH}; do
for y in seq ${MIN_LAT} ${HOR_SPACING} ${MAX_LAT}; do
for x in seq ${MIN_LON} ${HOR_SPACING} ${MAX_LON}; do
echo $x $y $z >> out.grd;
