**Context**
- Overlays (aka [[ https://www.mediawiki.org/wiki/Help:Extension:Kartographer#GeoShapes_via_Wikidata_Query | GeoShapes ]]) are predefined objects on the map that are tied to latitude/longitude coordinates.
- These polygons and way objects (countries, roads, parks, etc.) are defined in OpenStreetMaps (OSM) and replicated to appear on the maps in wiki projects. (see an example below)

//[[ https://en.wikipedia.org/wiki/Central_Park#/map/0 | Map overlay of Central Park in New York City ]]//
**Why**
-
**How**
- Because these map overlays are defined in OpenStreetMap, they need to be synced with our infrastructure in order to display the objects and stylings in Wikimedia projects.
- There has been a substantial lag in the syncing of these 2 systems mainly due to a failure in the [[ https://www.mediawiki.org/wiki/Help:Extension:Kartographer/OSM | OSM ]] replication tool, osm2pgsql, that performs the database updates.
