# ST_LUCAS QGIS Plugin

The plugin allows to interactively select the spatial, attribute, temporal and thematic filters from the GUI. In particular, it allows selecting an area of interest (spatial filter) by the extent of the map canvas, specifying a country from a list of EU countries or using a user-defined vector polygon data layer. The plugin interface allows specifying also a list of selected years (temporal filter) and a group of attributes (thematic filter). The plugin also integrates functionality for performing a user-defined class aggregation using a JSON file, a nomenclature translation using a CSV file and showing photos of a selected LUCAS point.

The plugin consists of three tabs:

- Download
  - Area of interest
  - Years
  - Groups of attributes
  - Space-time aggregation
  - Output GeoPackage
- Analyze
  - Class aggregation
  - Nomenclature translation
- Photos
