Base
Overview
The Overture Maps base
theme provides the land and water features that are necessary to render a complete basemap. These features are currently derived from the Daylight Earth Tables schema and include the Daylight Coastlines.
Schema design choices
- basic classification of features into
type
,subtype
andclass
where appropriate. - parsing and normalization of common OSM tags, such as
height
andele
. - extraction of consistent OSM tags, such as
wikidata
to top-level properties. - direct pass-through of remaining relevant OSM tags.
Current feature types
- infrastructure: Infrastructure features such as communication towers and lines, piers, and bridges.
- land: physical representations of land surfaces. Global land derived from the inverse of OSM Coastlines. Translates
natural
tags from OpenStreetMap. - land_use: classifications of the human use of a section of land. Translates
landuse
from OpenStreetMap tag from OpenStreetMap. - water: physical representations of inland and ocean marine surfaces. Translates
natural
andwaterway
tags from OpenStreetMap.
