Scripts
=======

Scripts that generate flowmaps for specific models:

- matroos_flowmap.sh (download model results for DCSM model and transform them to a flowmap)

Usage
=====

To use the software you can download the latest version using docker.
If you have docker installed you can download the software using the command:

.. code:: bash

docker pull openearth/flowmap

You can run the software by typing the command (for now please prepend the flowmap command with `/opt/conda/envs/py35/bin`.

.. code:: bash

# help
docker run openearth/flowmap flowmap --help

# help per command
docker run openearth/flowmap flowmap generate --help

# generate flowmap
docker run openearth/flowmap flowmap generate delft3doutput.nc --src_epsg=28992 --dst_epsg=3857

# compute subgrid interpolation
docker run openearth/flowmap flowmap subgrid delft3doutput.nc aw_refi_def_asc.tiff --src_epsg=28992

# export tables to nc format
docker run openearth/flowmap flowmap export --format tables --src_epsg=28992 delft3doutput.nc aw_refi_def_asc.tiff

# regrid the output to a tiff file can be done with gdal
gdal_grid -zfield subgrid_waterlevel groesbeek_map_waterlevel_last.geojson groesbeek_map_waterlevel_last_idw.tiff -outsize 16069 20071 -a invdistnn:power=3.0:max_points=4:radius=8 -txe 188819.156 196867.156 -tye 426992.399 416956.899

# extracting the relevant contour

In the case of Delft3D you can convert the default nefis output to netCDF using the vs_trim2nc.m matlab script.
There is also direct nefis support in development, but that has not been properly tested.
By default you will want to project to the web mercator projection. Then you can reuse the velocities as pixels/s in an animation.
