Add subcommand `gribmagic smith bbox`, to extract an area of interest

[amotl]

About

Extract area of interest from GRIB files using a bounding box.

Examples

Extract subset by coordinates, a space-separated list of lat_min lat_max lon_min lon_max.

gribmagic smith bbox \
  ".gribmagic-data/raw/icon-d2/**/*regular-lat-lon*.grib2" --output=.gribmagic-data/subgrid \
  --bbox=46.0 47.5 14.5 16.8

Extract subset by two-letter country code.

gribmagic smith bbox \
  ".gribmagic-data/raw/icon-d2/**/*regular-lat-lon*.grib2" --output=.gribmagic-data/subgrid \
  --country=AT

For plotting the results on a map and rendering them to .png files, install Magics and use the --plot option:

make magics-install
export MAGPLUS_HOME=/usr/local/opt/magics-4.9.3

gribmagic smith bbox \
  ".gribmagic-data/raw/icon-d2/**/*regular-lat-lon*.grib2" --output=.gribmagic-data/subgrid \
  --country=AT \
  --plot
