Description

In principle, there is already a hierarchy based on the shapefiles/location. This means that you can already see which space is within which other space. (It can be seen quite easily at the database level because you can easily see that the shapefile of Apeldoorn is located within the shapefile of the larger region and that is within the shapefile of the country etc. ) This parenting relationship between reference spaces is currently saved within the database, but there isn't really a user interface where this can be seen.

Therefore, this user interface should be created.

This is already done within cities (we know that infrastructures are within a city and can be used in the master map). In the future, it would be important that we show relationships between other reference spaces. For instance, cities within NUTS3, 2, … countries, regions of countries. This hierarchy between the scales (from closest to furthest) should become evident. --> The system would demonstrate that Apeldoorn is within NUTS3 Veluwe and NUTS 2 - Gelderland. And that Veluwe is in Gelderland.
What is more, it should also reveal what kind of data exists on these other levels:

WHY: This will help if we consider downscaling in the future, to look for data that are closest to the city (making them a priori the most accurate). For example, if I don't have crop data for Apeldoorn, but there is crop data for Veluwe, it would be great to have this suggested, that this exists in the system.

Before you start this task, please discuss with Paul what kind of code you suggest to implement, before rolling it all out. He can then talk technical details with you.
