Introducing OpalAI’s Newest Offering: Custom IMDF File Creation for Enhanced Indoor Mapping

At OpalAI, we're thrilled to unveil our latest breakthrough in indoor mapping technology: a bespoke service that transforms CAD datasets into the highly versatile Indoor Mapping Data Format (IMDF). IMDF is a comprehensive, Apple-developed format designed to enable precise indoor mapping across a myriad of devices and applications.

Before diving into our process of transforming CAD data into IMDF files, let's explore the significance of IMDF and its advantages over other formats.

Understanding IMDF

IMDF has been meticulously designed to cater to developers, venue owners, and organizations that require a detailed and accurate representation of indoor spaces. Its target audience spans across various sectors, including retail, airports, museums, corporate campuses, and more. By providing a universal standard for indoor maps, IMDF facilitates easier creation, consumption, and sharing of indoor space data, integrating seamlessly with location-based services and indoor navigation solutions.

What this means for you

Compared to other formats, IMDF offers unparalleled precision and flexibility. It allows for detailed mapping of complex indoor environments, including multiple floors and intricate layouts, without sacrificing usability or performance. IMDF's JSON-based structure supports extensive metadata and custom attributes, making it not only a spatial dataset but also a rich source of information about the indoor environment. This depth of detail supports a wide range of applications, from wayfinding to resource allocation and beyond.

Furthermore, IMDF is designed with scalability and interoperability in mind. It can easily be integrated with existing Geographic Information System (GIS) technologies and indoor positioning systems (IPS), providing a robust framework for developers to build upon. Its open nature encourages innovation and adoption, setting a standard for the future of indoor mapping.

IMDF files are compatible with your app/website and Apple Maps

How we bring IMDF files to life

The following steps outline OpalAI’s approach to IMDF creation:

  • Begin with preparing a comprehensive Master file by compiling all necessary layers for an accurate conversion base.

  • Preprocess data through meticulous manipulation and enhancement to align floors, standardize attributes, and meet specific standards.

  • Develop custom solutions to address common issues such as misaligned layers and inconsistent naming, including georeferencing for accurate real-world mapping.

  • Manually refine data to ensure the highest accuracy and detail, addressing anomalies that automated processes might miss.

  • Utilize advanced programming techniques to restructure cleaned data into a hierarchical format for IMDF, making indoor maps navigable and user-friendly.

  • Employ scripting and custom tools for data structuring, detailed georeferencing, and accurate element representation in the map.

  • Subject each IMDF file to a rigorous validation and quality assurance process, combining automated tools and manual reviews to ensure standards compliance, accuracy, and completeness.
