Pilot NoiseModelling with scripts

In this tutorial, we describe the different ways to pilot NoiseModelling thanks to scripts. To do so, we will use a dedicated packaging of NoiseModelling, called NoiseModelling_4.0.0_without_gui, in which the GUI has been removed (no more Geoserver and WPS Builder).

  1. Go to the NoiseModelling latest release page
  2. Download and unzip the NoiseModelling_4.0.0_without_gui file

From that point, NoiseModelling can be executed in 3 different maners:

  1. with simple command lines
  2. with Bash script
  3. with Groovy script

To illustrate, users are invited to reproduce the tutorial “Get Started - GUI” in command lines.

Note

This tutorial is mainly dedicated to advanced users.

Requirements

Warning

For all users (Linux , Mac and Windows), please make sure your Java environment is well setted. For more information, please read the page Requirements.

1. Simple command line

Below is an example of a bash instruction, executing the Noise_level_from_traffic.groovy WPS Script (located in the directory /noisemodelling/wps/). This block has 5 arguments corresponding to the input table names (for buildings, roads, receivers, dem and ground type).

cd /home/user/NoiseModelling_4.0.0_without_gui/

./bin/wps_scripts -w./ -snoisemodelling/wps/Noise_level_from_traffic.groovy 
tableBuilding=BUILDINGS tableRoads=ROADS tableReceivers=RECEIVERS 
tableDEM=DEM tableGroundAbs=GROUND_TYPE

./bin/wps_scripts instruction allows to launch the wps_scripts.sh or wps_scripts.bat (depending on if you are on Linux / Mac or Windows) file, which is located in the bin/ directory.

Warning

Adapt /home/user/ address with your own situation

2. Bash script

Below is an example of a sequence of simple .groovy scripts, using bash instructions and launching the differents steps described in the “Get Started - GUI”.

# Step 6: Export (& see) the results

3. Groovy script

Below is an example of a complex .groovy script, launching the differents steps described in the “Get Started - GUI”.
