Package	Description
io.goobi.viewer.model.maps	Provides the core domain model for geo-maps in the Goobi viewer, including map configurations, feature sets, markers, filters, and Solr-backed spatial data providers.
io.goobi.viewer.model.maps.coordinates	Provides parsers and readers for converting geographic coordinate representations such as GeoJSON and WKT (point and polygon) into internal coordinate objects.

Class	Description
AbstractFeatureDataProvider	Abstract base class for geo map feature data providers that execute Solr queries and convert the results into MetadataDocument instances for downstream feature generation.
DocStructDataProvider	Feature data provider that retrieves structural document elements (DOCTYPE:DOCSTRCT) from Solr for use in geo map feature generation, supporting large result sets via query expansion.
FeatureGenerator	Converts MetadataDocument objects retrieved from Solr into GeoJSON GeoMapFeature instances for rendering on geo maps.
FeatureQueryGenerator	Generates Solr search filter queries for geo map features based on coordinate and label metadata extracted from a given MetadataContainer.
IFeatureDataProvider	Strategy interface for retrieving MetadataDocument results from a data source (e.g. the Solr index) based on a query and optional facet filters.
LabelCreator	Creates localised label values for geo map features by applying configured metadata templates to a given MetadataContainer.
MetadataDataProvider	Feature data provider that retrieves Solr metadata documents (DOCTYPE:METADATA) and their parent top-level records for use in geo map feature generation.
MetadataDocument	Aggregates a Solr main document together with its inline metadata, grouped METADATA child documents, and structural child docstructs, used to supply data for geo-map feature generation.
RecordDataProvider	Feature data provider that retrieves top-level records (works and anchors) from Solr, optionally including their child metadata group documents for geo map feature generation.
RelationshipDataProvider	Feature data provider that extends MetadataDataProvider to additionally resolve relationship metadata by loading related Solr documents for each retrieved metadata group.
