Vortex importer scripting example

The Vortex API is written in java allowing access via jython scripting. The following example demonstrates importing a grib file via jython script.

This batch script example uses two scripting files:

1. A *.py file that contains the scripting logic
2. A *.bat file that sets the environment and executes the python script

In addition to the script files, two jars were used:

1. A version of vortex
2. A version of jython-standalone.jar

The python script met_data_import.py imports a grib file to a dss by interacting with the Vortex API:

from mil.army.usace.hec.vortex.io import BatchImporter
from mil.army.usace.hec.vortex.geo import WktFactory

in_files = ['C:/Temp/MRMS_GaugeCorr_QPE_01H_00.00_20170102-120000.grib2']

variables = ['GaugeCorrQPE01H_altitude_above_msl']

clip_shp = 'C:/Temp/Truckee_River_Watershed_5mi_buffer.shp'

geo_options = {
    'pathToShp': clip_shp,
    'targetCellSize': '2000',
    'targetWkt': WktFactory.shg(),
    'resamplingMethod': 'Bilinear'
}

destination = 'C:/Temp/myPythonImport.dss'

write_options = {'partF': 'my script import'}

myImport = BatchImporter.builder() \
    .inFiles(in_files) \
    .variables(variables) \
    .geoOptions(geo_options) \
    .destination(destination) \
    .writeOptions(write_options) \
    .build()

myImport.process()

The batch script met_data_import.bat sets the environment and executes the script:

set "VORTEX_HOME=C:\Programs\vortex-0.11.2"
set "PATH=%VORTEX_HOME%\bin;%VORTEX_HOME%\bin\gdal;%PATH%"
set "GDAL_DATA=%VORTEX_HOME%\bin\gdal\gdal-data"
set "PROJ_LIB=%VORTEX_HOME%\bin\gdal\projlib"
set "CLASSPATH=C:\Programs\jython-standalone-2.7.2.jar;%VORTEX_HOME%\lib\*"
%VORTEX_HOME%\jre\bin\java.exe -Xmx2g -Djava.library.path=%VORTEX_HOME%\bin;%VORTEX_HOME%\bin\gdal org.python.util.jython met_data_import.py

This example can be found on github.

That's all there is to it. Happy scripting!
