Elastic Maps Service (EMS) enhances geospatial visualizations in Kibana by providing basemap tiles, region map boundaries, and key attribute data, including new vector map layers for country subdivisions like Australian states and Swiss cantons. These layers use the ISO 3166-2 codes for unique identification, allowing users to visualize web traffic by country subdivisions. To achieve this, users can leverage the Logstash GeoIP filter or the Ingest GeoIP Processor to add location data from the MaxMind GeoIP databases, and subsequently create a Painless scripted field to join the data with region maps. Kibana version 6.4 introduces a preview feature for scripted fields, facilitating the creation of region maps for specific countries using these subdivisions. EMS continues to expand its offerings with more vector map layers, which are accessible without requiring updates to Elasticsearch or Kibana, with region maps available from Kibana version 5.5 onwards.
