OGC updates container format GeoPackage and approves indoor mapping format

Information from OGC

In approving GeoPackage V1.3, the Open Geospatial Consortium (OGC) has made a minor update to the current version 1.2.1. The consortium has also adopted Apple’s Indoor Mapping Data Format (IMDF) 1.0.0 as an OGC standard.

Minor update to GeoPackage

V1.3 is a minor update to GeoPackage, the open, standards-based, platform-independent, portable, self-describing, compact format for transferring geospatial information.

GeoPackage builds on the industry-standard SQLite relational database, and can store multiple datasets, data types, and metadata records in the same file, minimising cumbersome and inefficient file manipulation.

In addition to a number of administrative changes to improve readability, clarity, and correctness, the following substantive changes were incorporated:

  • Enforce alignment of Spatial Reference System (SRS) Identifiers between tables.
  • Clarify use of views in user-defined tables.
  • Relax Requirement 104 to allow use of schemas with attributes and extensions.
  • Allow metadata scopes to be extended.
  • new Requirement 152 to describe empty geometries.

Format for creating indoor map apps and service

The OGC has also approved the Indoor Mapping Data Format (IMDF) 1.0.0 as a standard. IMDF enables anyone to create indoor map apps and services using the same highly accurate and detailed data on any app, website, or operating system.

The format provides a mobile-friendly, compact, human-readable, temporally aware, highly extensible data model for any indoor space, providing a basis for orientation, navigation, and discovery.

IMDF was proposed by OGC members Apple, Autodesk, Esri, Google, New York City Department of Information Technology and Telecommunications, Ordnance Survey Limited, and Safe Software. Apple developed IMDF to deliver indoor maps for venues around the world.

Like all OCG standards, the GeoPackage and IMDF standards are free to download and implement.
