Overview
Indoor Mapping Data Format (referenced throughout this document as "IMDF") provides a generalized, yet comprehensive model for any indoor location, providing a basis for orientation, navigation and discovery. In this release there are also detailed instructions for modeling the spaces of an airport, a shopping mall, and a train station.
This release also has an extension model which enables a venue, organization, or even an industry to create valid features and validations not available in the current specification for private or public use
Developers can access both text and visual examples of all features, along with clear explanations of all terms. IMDF conforms to RFC 7946, ensuring compatibility and transferability of the data. IMDF is lightweight, mobile friendly, and can be rendered on any device, OS, or browser.
For GIS and BIM specialists, there is support for IMDF in many of your favorite tools.
IMDF maps integrated with indoor positioning can establish the foundation for a wide range of consumer and enterprise location-based apps and websites.
