Cliopatria shape dataset

Clone the Cliopatria GitHub repository.
Unzip the file cliopatria.geojson.zip.
Enter the notebooks directory and set up the Python environment as per the instructions in the README.md file in the same directory.
Run the following command to add colours to the dataset:
```
$ python convert_data.py ../cliopatria.geojson
```
This will create a new file with the name “cliopatria_seshat_processed.geojson”. Note: You can preview the file in the Jupyter notebook found in the notebooks directory. Instructions on how to run the notebook are found in the README.md file in the same directory.
Go back to the Seshat repo on the machine the website code is running from (if you are running it on a remote server, upload the processed GeoJSON). With your Seshat Python environment activated, you can populate core_cliopatria table using the following command:
```
$ python manage.py populate_cliopatria /path/to/cliopatria_seshat_processed.geojson
```

GADM

Download the whole world GeoPackage file from the GADM website.
Populate the core_gadmshapefile, core_gadmcountries and core_gadmprovinces tables using the following command:
```
$ python manage.py populate_gadm /path/to/gpkg_file
```

How to add new shape datasets to the maps

Ensure that the database and Django are already set up (see the relevant setup page for more detail) and all migrations have been run for the “core” Django app (python manage.py migrate core).

To create a new shape dataset for use in the Seshat map explorer, you can do the following:

Create a new model for the new dataset in seshat/apps/core/models.py

Generate migration from model, and run it for your database to create the table

$ python manage.py makemigrations core
$ python manage.py migrate core

Create a new “command” at seshat/apps/core/management/commands which can be used to populate the db table from the dataset files - See the examples below - Add a new header on this page to document here how this works
Create a new view and update the the map template with the necessary logic to use this dataset - views at seshat/apps/core/views.py - template e.g. seshat/apps/core/templates/core/world_map.html
