JSON-2-TAB

The JSON-2-TAB converter is a command line tool and library to crop global JSON windturbine database to domain specific TAB-file.

Optionally this tool can generate plots to visualize results, therefore only some additional optional python packages need to be installed. These are grouped in the plotting group in the poetry project configuration

Setup

Installation

To install the core of the JSON-2-TAB converter just call

make install

To install the JSON-2-TAB converter including the plotting functionality one can use the following install option

make install/plotting

Preparation

When using json2tab it is expected that the static_data is prepared. Most of the statc_data files are already stored in the repository; but some has to be downloaded. To prepare the static_data folder run the make command in that folder, i.e:

cd static_data && make

Note: The make command worldmap/eez is likely to fail due to required user interation. So to continue preparation of static data download www.marineregions.org/download_file.php?name=EEZ_land_union_v4_202410.zip and save it to static_data/worldmap/eez/EEZ_land_union_v4_202410.zip

Afterwards rerun the make command:

cd static_data && make

Now all static data needed to run JSON-2-TAB is installed in the static_data folder.

Usage

After installation of json2tab one can use the commandline interface using options as listed by

json2tab --help

Meta-data generation: instructions to build (or update) master turbine location database

The input data to create the master turbine location database (a.k.a. euromap) is basically split in two main categories of data;

1. The first part is collecting so called static_data; this is static data that is expected not to change. For example information about country borders or the known wind turbine type database.
2. The second part is called web_data and is about collecting country/source specific wind turbine location information. Different countries/sources might have different update intervals to update the wind turbine location information. Therefore, to update the master turbine database one can update the web_data folder and all sources where new data is expected will fetch the latest wind turbine location information.

With both a populates static_data and web_data we can use json2tab's convert, map and merge functionality to combine and build a single master wind turbine location file.

Euromap build/update procedure

To build your own version of the master turbine location database use the following instructions:

1. Install optional packages needed for euromap generation: make install/euromap_generation
2. Enter folder euromap
3. Run make web-update
4. Run make

Note: it is assumed you have the JSON-2-TAB package installed and the static_data downloaded; if you haven't done it see section Preparation how to do it.

Data sources for master turbine database

The master turbine database combines wind turbine location information from different sources. At the moment data from the following countries/sources are used:

• Austria
• Belgium [Flanders + Offshore]
• Bulgaria (static)
• Denmark (yearly?)
• EMODnet
• Finland (static)
• France (daily)
• Germany (daily)
• Greece (manual)
• Italy (static)
• Netherlands [onshore: RIVM, offshore: RWS] (yearly)
• OpenStreetMap (daily)
• Sweden (daily)
• United Kingdom (quarterly)
• wf101 [Old Austrian dataset based on flight obstables]

Note: For some countries there is not automated procedure to update country information; for these countries the make web-update will create a text-file with instructions how to fetch data for these countries.
