Is KML an OGC standard?

KML, or Keyhole Markup Language, is indeed recognized as an Open Geospatial Consortium (OGC) standard. Developed initially for use in Google Earth, KML allows users to visualize geographic data in an Earth browser. The adoption of KML as an OGC standard means it adheres to established protocols and guidelines, promoting interoperability and making it easier to share and use geographic data across various applications and platforms.

KML is standardized under the OGC to ensure that it can be utilized uniformly across different software and systems that support geospatial data. This standardization facilitates better data exchange and collaboration in projects that involve geographic information.

In regard to the other options, KML is not currently under development as a standard, which rules out the notion of it being a developing standard. Furthermore, while KML is widely used in various applications, it does not hold a status as an OGC standard only in certain applications; rather, its standardization by the OGC applies universally across all its implementations.
