About this format
KML format context
Format: KML
Overview
KML matters because it became the mainstream way to package placemarks, overlays, and earth-browser style geographic presentations for visual map consumption rather than raw developer interchange.
Earth-browser and visual map workflows needed a format for placemarks, overlays, and geospatial presentation layers.
KML remains common for visual geographic sharing, overlays, and earth-browser style presentation workflows.
KML is closely associated with Open Geospatial Consortium.
KML is usually selected for workflows that center on system exchange, automation, specialized interoperability.
Typical Workflows
- system exchange
- automation
- specialized interoperability
Common Software
- Google Earth
- QGIS
- map overlay tools
Strengths
- Good for visual geospatial overlays and placemarks.
- Strong association with Earth-browser style presentation.
- Readable XML structure for many exchange tasks.
Limitations
- Less convenient than JSON-based formats for developer-first API workflows.
- Presentation-heavy constructs do not always map neatly into other GIS formats.
Related Formats
- KMZ
- GEOJSON
- GPX
Interesting Context
KML is strongly associated with the Google Earth ecosystem and was later standardized through OGC.
KML belongs to Google Earth publishing, tourism and property map overlays, GIS exports, geospatial storytelling, and cross-platform map visualization workflows.
It remains widely recognized by mapping software because it became the canonical format for Earth-browser content and portable geographic overlays.
Status: active. Introduced: 2004. Invented by: Keyhole, Inc.. Stewarded by: Open Geospatial Consortium.
How KML fits into workflows
Workflow role: KML
Convert to KML when the output needs to open cleanly in Google Earth or another Earth-browser workflow, especially for annotated map layers, site plans, territory overlays, and location datasets that benefit from styling and folder-based organization.
History of KML
Format history: KML
KML is strongly associated with the Google Earth ecosystem and was later standardized through OGC.
Original problem: Earth-browser and visual map workflows needed a format for placemarks, overlays, and geospatial presentation layers.
Why KML still matters
Current role: KML
KML matters because it became the mainstream way to package placemarks, overlays, and earth-browser style geographic presentations for visual map consumption rather than raw developer interchange.
Modern role: KML remains common for visual geographic sharing, overlays, and earth-browser style presentation workflows.
When to use KML
- system exchange
- automation
- specialized interoperability
