The Ultimate Guide to Indoor Maps for Enterprises: The Building Blocks for Smarter Spaces

15 minute read

The way we experience indoor spaces is about to change dramatically, and it is today’s enterprises that are leading the charge. While it is certainly a bold claim to say that technological innovation is going to completely revolutionize our experience of place in the next few years, it is a substantiated one when we observe the shifts already happening. When it comes to smart spaces and a new experience of place, the wheels of change are already well and truly in motion, and we are well on our way to creating a more connected world.

 Ultimate Guide to Indoor Mapping for Enterprises

When one considers the innovations in outdoor navigation that have taken hold over the last two decades, it should come as no surprise that change is also on the horizon for the great indoors. It is only a matter of time before the GPS-enabled outdoor experiences that we have come to expect will be complemented by similar interactions with our indoor environments as well. Intelligent wayfinding and proximity-based messaging shouldn’t - and soon, won’t - cease when you walk through the doors of a building. 

Enterprise organizations are in an especially powerful position to not only lead the charge in reshaping the world via indoor intelligent connectivity, but also to capitalize on those changes as early adopters. In this guide, we’re going to cover off:

  • definitions around indoor intelligence and smart building technologies;
  • explore what kinds of use cases indoor maps can power;
  • explore some case studies from other enterprise organizations in various industries;
  • and outline what the first steps are to laying the foundation for smarter buildings.

Clarifying Key Terminology

As with any other emerging industry, the hype around smart spaces has helped generate an abundance of buzzwords and jargon that can overcomplicate the key concepts. It’s important that we look beyond the buzz and establish a solid comprehension of the key terms to understand what exactly is going on in the world of indoor intelligence and connectivity.

The Internet of Things (IoT)

The Internet of Things, usually referred to as IoT, is a network of devices (things) and the connectivity which allows these things to connect, interact and exchange data (the internet part). Simply put, IoT is a network of things that are all connected to a platform that aggregates and collates the data from each device.

What does IoT have to do with indoor maps and smart buildings? In a smart building, your indoor positioning devices and beacons, the mobile phones within the building, and your indoor maps are connected via a network to provide real-time location information in the form of navigation or tracking. Indoor mapping and navigation projects are Internet of Things projects.

Smart Buildings

There’s plenty of talk about smart buildings, but what actually is a smart building, and what makes one ‘smart’? Smart buildings essentially use IoT technology to monitor and control building systems and operations. By leveraging pervasive wireless connectivity, sensors, and IoT technologies, they are able to communicate and analyze data, manage indoor security, and optimize building controls, lighting, HVAC, and more. These same technologies can also be used to remove friction from daily interactions, as we often see in the context of smart offices and connected corporate campuses. Smart buildings can also leverage AI and machine learning to optimize energy efficiency by controlling lighting schedules, temperature monitoring, power supply and distribution, and more.

Digital Twins

A digital twin is a virtual representation of a physical environment that collates and presents data from a variety of sources. This also extends to digital representations of your connected devices. It’s basically a digital replica of an asset, like a building, and everything inside it. For example, there could be a device twin for each of your IoT devices, and there would be a JSON file in the cloud for each of the devices, viewable using a platform like Inpixon's.

Indoor Maps

You may be wondering, what are indoor maps and why do they matter? Where do they fit into smart buildings? Indoor maps actually play a monumental role in the creation of smart spaces- they are the starting point for any project that requires location-awareness within an application. Would you like people to be able to use a kiosk or an app to get around your building? You’ll need an indoor map. Do you want to visualize data from sensors in relation to your building? You’ll need an indoor map.

Indoor Mapping

Indoor mapping is the process of converting floor plans into digital, interactive representations of indoor spaces. In addition to serving as a wayfinding platform, indoor maps leverage business rules, localization and the IoT to enable users to visualize spatial data, creating real-time ‘indoor location intelligence’. With Inpixon's indoor mapping platform, any system can be enhanced to display data in the context of an indoor map and buildings can become digitally addressable.

 

 

Digging Deeper on Indoor Maps

Not all indoor maps, or indoor mapping platforms for that matter, are created equally. When indoor mapping and map digitization is done well, the maps can look very simple, but it takes a lot of work to make effective, intuitive, IoT-enabling indoor maps. Having basic floor plans or the original architect’s drawings of your building is a great starting point, but the indoor mapping process is key to turning them into something meaningful and useful. In the process of digitizing your maps and making your space digitally addressable, there are several key components that separate the weak mapping providers from the strong.

If you have your building drawings in a digital format, you may be wondering why you can’t just use the maps you have now as they are. What it comes down to is the fundamental differences between static and dynamic, interactive maps.

A static map is an image with no interactive elements. It can be added to a webpage using HTML, but you can’t embed elements or geotag assets within the map - they’re just pictures that are available to be viewed. Static maps are essentially the web equivalent of keeping a stack of paper maps at the building entrance. By contrast, dynamic maps are interactive objects that allow users to engage with them. Your indoor maps need to be dynamic in order to do anything of value.

Another important thing to note about indoor maps is the importance of geospatial accuracy.  How is the map of your building affixed to the world map? It may sound trivial to ponder the nuances of map projections, but knowing how to fit your two-dimensional map onto a three dimensional globe is actually very important. As an example, you need to know where your building sits in relation to the outdoor world to enable accurate outdoor-indoor navigation with other mapping platforms. Geospatial accuracy is also an important factor in determining indoor wayfinding routes, especially when there are multiple floors and street level entrances.

Another point of differentiation between many mapping providers is the ability to create different customized experiences using a single set of maps. You shouldn’t need to have a different map for each user profile using the same space. For example, if you have a building with ten floors, and five different user profiles for staff, visitors, etc, then you should have a set of ten maps - not fifty unique maps that require manual updating with every change. Your indoor mapping platform should empower you to cater to different users by serving customized visualizations of your space based on a user’s profile with a single map instance.

The last, and potentially most important, point about indoor maps is the absolute necessity of interoperability. In an IoT-enabled smart building, especially at the enterprise level, no one vendor is going to be able to deliver on all of an enterprise’s current and future use case needs. Therefore, it is imperative that the vendors being selected by enterprise organizations have open architectures to support easy integration with third-party solutions. The keys to interoperability lie in Rest APIs, robust SDKs, and a commitment to extensibility, and you should always ask indoor mapping providers how they integrate with others.

What Can You Do with Indoor Maps?

A better question might be “what can’t you do with indoor maps?” For innovative enterprises, the sky is the limit. We’ve seen offices completely transformed into smart workplaces where employees can work more efficiently and facilities management processes are optimized. We’ve seen hospitals take steps towards reducing wait times and provide patients with outstanding navigational experiences. In every industry, we are seeing companies roll out indoor mapping projects as they commence their digital journey.

From navigation and asset tracking to proximity messaging, location sharing and beyond, if you can dream it, you can do it. Explore common enterprise use cases here.

Getting Started with Indoor Maps

The beauty of good indoor maps lies in their versatility. Once you have a set of geospatially accurate, digitized indoor maps, there are a wealth of use cases you can implement throughout your facilities.

How You Get the Maps into Apps

So, how do you build apps with maps in them? It all starts with Software Development Kits (SDKs) and plugins.

SDKs are the starting point for almost every program you can name. From your web browser to video games and mobile apps, many of these will have started with an SDK. When it comes to Inpixon, our SDKs allow your developers to focus on integration, styling and user experience. Essentially, our SDKs have already done the heavy lifting for you.

What exactly is an SDK? Keeping the ‘kit’ part in mind is very helpful when we’re talking about SDKs. As Inpixon's Enterprise Solutions Architect Aaron Wong explains it, “when you’re building a model airplane, you need the full kit of tools, instructions, glue, and parts that come in the box in order to assemble the model properly. An SDK (also sometimes aptly called a ‘devkit’) works in a very similar manner, providing a set of tools, libraries, relevant documentation, code samples, processes, and guides that allow developers to create software applications on a specific platform.”

Similarly, a plugin is a software extension that adds a specific feature to an existing computer program requiring minimal coding, or sometimes none at all. You can think of it as another mini SDK to enhance the primary SDK. When a program supports plugins, it enables customizations and permits the developer to enhance the capabilities of an app. Essentially, enterprise development teams can leverage indoor mapping platform SDKs to get maps in their apps quickly, and customize them to meet their needs.

Getting Granular: Mapping File Formats You Need to Know

Throughout the indoor mapping process, you will find that there are several important file formats you’ll encounter in your indoor mapping journey.

GeoJSON

GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes. It is based on JSON (JavaScript Object Notation). GeoJSON features include points (ie. addresses and locations), line strings (ie. streets, highways, and boundaries), polygons (ie. countries, provinces, tracts of land), and multi-part collections of these types. GeoJSON features aren’t limited to representing physical entities. Mobile navigation apps for both indoor and outdoor environments may describe their service coverage using GeoJSON. The GeoJSON format does differ from other GIS standards in that it was written and is maintained by a group of developers, not by a formal standards organization.

IMDF 

IMDF (Indoor Mapping Data Format) is the closest thing we have to an industry standard format, at this point. It is a standardized data model used to describe a venue. IMDF can be rendered on any device and is the first step to enabling indoor positioning for iOS apps. Under the hood, it’s a package of GeoJSON files that meet specific data model requirements.

Inpixon underwent Apple’s extensive process to validate the creating and updating of IMDF through our APIs. Being a validated provider extends developers the ability to work with Inpixon's APIs to address a variety of indoor mapping use cases including indoor wayfinding, asset tracking and more.

Setting Your Enterprise Up for Success

The winds of change are quite literally in the airwaves, and enterprises are being handed the opportunity to become their own digital landlords in a meaningful way. As we move towards a 5G-enabled world, we’ll only see more and more uptake from organizations across enterprises as bandwidth requirements become less of a blocker. The enterprises that start taking steps today to lay the foundation for their future IoT projects by establishing the building blocks of open architectures and digitized maps are the organizations that will be in a position to succeed in the coming years.
