Introduction

On worksites (factories, construction sites, warehouses, etc.), it is often difficult to keep track of who is doing what and where, which can contribute to reduced productivity and communication losses. In traditional site management, it was not unusual to see situations where someone trying to give work instructions had trouble locating the person in charge, or veteran supervisors rushed around the site to check conditions. However, with advances in digital technology, "visualizing people’s locations" has become possible, and site management methods are starting to change significantly. By visualizing the real-time location information of people working on-site, initiatives that lead to productivity improvements and enhanced safety are attracting attention across industries. This article explains in detail the role that visualizing people’s locations plays within the flow of on-site DX (digital transformation), its effects, and points to consider when implementing it.

What is On-site DX?

First, let’s confirm what on-site DX is. DX (digital transformation) refers to efforts to transform business and operational processes using digital technologies to create value and strengthen competitiveness. On-site DX specifically focuses on operations at the "site" such as factories and construction sites, and refers to making daily work processes more efficient and advanced through digital technologies. Examples of on-site DX include sharing progress management that used to be done with paper slips or whiteboards in real time on the cloud, and optimizing work planning that previously relied on the intuition and experience of skilled workers through sensor data and AI analysis. The essence of on-site DX is not simply introducing IT devices to the site, but updating the culture of the site itself by changing decision-making and communication methods based on data.

Against a backdrop of population aging, labor shortages, and increasing demands for improved safety, on-site DX has become an indispensable issue in many industries. Promoting on-site DX is expected not only to improve productivity and quality and create new value, but also to contribute to work-style reforms and improvements in working conditions. Among these efforts, "visualizing people’s location information" is an important initiative that symbolizes on-site DX.

Challenges of On-site Management and the Need for "Visualization"

Several challenges have been pointed out in traditional site management. For example, in large factories or construction sites, it is difficult to accurately know "who is where right now," so managers needed to confirm by radio or phone or patrol the site directly. Time can be wasted searching for workers, and time lags can occur before information reaches the right person, lowering operational efficiency. In addition, if a problem occurs in an area outside the manager’s sight, there is a risk of delayed response.

Moreover, personalized management has its limits. Veteran supervisors can grasp site conditions from experience, but that knowledge and intuition are difficult to share with others, and management that relies on individual skills can make overall optimization difficult. The idea of "visualization" is to create a state in which "what is happening on-site can be objectively seen by everyone." Data such as temperature and production counts are beginning to be visualized by sensors, and information about people’s movements and locations is another area where visualization is required.

By visualizing, it becomes possible to capture what used to be sensed intuitively at the site as data. Who did what, where, and when; which routes were taken; how long was spent on work or waiting—if such information becomes visible as data, it becomes easier to discover inefficiencies, wastes, and unevenness (muda, mura, muri) on site. In other words, visualization is the first step in solving on-site problems.

What Is "Visualizing People’s Locations"?

So, what exactly does "visualizing people’s locations" refer to? Simply put, it is a system that collects the real-time location information of people working on-site and visualizes it on a map or similar display. The image is of each worker’s current position being shown on a factory floor map or a construction site layout. Managers can view the whole site on a PC or tablet screen and instantly grasp each person’s location and movements.

Various technologies are used to realize this system. Outdoors, GPS can be used to acquire location from workers’ smartphones. In indoor or GPS-denied areas, systems that use BLE beacons (Bluetooth Low Energy transmitters), UWB (ultra-wideband), Wi‑Fi signal strength, or RFID tags are used to determine position. Workers carry small transmitters or have tags attached to helmets or uniforms, and sensors installed on-site detect them to capture people’s whereabouts in real time.

Collected location data are aggregated in cloud or on-premises systems and visualized by displaying people’s icons on a map. This makes it easy to know, for example, which area a person in charge is currently working in or how far a patrolling staff member has circulated within a facility. Advanced visualization can display movement history as tracks on the map for a given time period or show areas with long dwell times as heat maps, not just current positions.

In short, "visualizing people’s locations" means capturing people’s movements with digital sensors and overlaying that information on spatial data of the site so it becomes visible. This enables not only on-site managers but also managers and related departments located remotely in offices to share real-time on-site conditions.

Why Visualizing People’s Locations Improves Productivity

So, why does visualizing people’s location information actually lead to productivity improvements? Here are some main reasons.

• Wasteful movement and waiting time reduction: Analyzing people’s location data reveals how workers move around. This makes it possible to identify inefficiencies such as material storage being too far away causing long round trips, or waiting time occurring while workers wait for instructions. For example, at one factory, analysis of worker movement data led to rethinking frequent trips to retrieve materials and changing material placement, which significantly reduced time spent moving. In this way, visualizing location information directly leads to improvements that reduce unnecessary movements and increase work efficiency.

• Optimization of personnel allocation: If you know in real time who is where, it becomes easier to allocate the right people to the right places. For example, when urgent help is needed in the field, you can immediately identify nearby staff and send them to assist. If too many workers are concentrated in one area and other areas are understaffed, visualization helps you rebalance staffing. This corrects personnel shortages and surpluses across the site and allows efficient use of manpower.

• Smoother communication: Visualizing locations also improves communication inside and outside the site. Managers no longer have to search for "Where is that person now?" and can check on-screen and contact them directly. It reduces unnecessary calls and announcements and makes it possible to deliver necessary instructions quickly to the necessary people. Sharing real-time site information with remote headquarters or partner companies also smooths situation explanations and reporting.

• Enhanced safety management: Knowing workers’ positions can improve safety. You can set alerts when someone approaches a hazardous area or confirm that everyone has entered designated safety checkpoints before starting work. In case of disaster or accident, you can immediately grasp who is where, enabling quick rescue or evacuation guidance. Continuous monitoring of people’s movements can help detect suspicious behavior or unauthorized entry into restricted areas early.

• Operational improvement and personnel development: Accumulating and analyzing people’s location data can be used to improve on-site operations. For example, data can reveal which tasks take longer and how movements differ between experienced and novice workers. As a result, bottleneck processes can be identified and addressed, and excellent work procedures can be standardized. Showing site realities with objective data is also useful for training less experienced personnel. Location visualization can be used as a tool for workers to review and improve their own movements.

As described above, visualizing people’s locations is not mere surveillance but a data infrastructure that comprehensively raises productivity, safety, and communication on-site. In actual domestic and international cases, DX using location information has reported results such as "search time reduced by XX%," "productivity improved by reviewing personnel allocation," and "achieved zero unauthorized entry into hazardous areas."

How On-site DX Is Changing Conventional On-site Management

Initiatives in on-site DX, typified by visualizing people’s locations, are significantly changing conventional on-site management. One major change is the shift to data-driven management methods. Previously, site supervisors used their five senses and experience to grasp conditions; now sensors and systems can collect uninterrupted data 24/7. Reliance on intuition and experience is reduced, and a culture of making decisions based on objective data is beginning to take root.

Also, because the site can be monitored remotely in real time, the need to "stick to the site to manage" is being reconsidered. It becomes possible to centrally monitor and direct multiple locations, or check site progress from home or the office, enabling location-independent management. This brings changes to work styles and is expected to reduce the burden of supervisors being constantly tied to the site for long hours.

On-site DX also strengthens organizational coordination by sharing visualized information. For example, if the placement and progress of workers on a production line are visualized, information can be passed seamlessly to adjacent processes and management departments, making it easier to build a team-wide rapid response system. The old assumption that "only people on-site know the site" is changing, and anyone can discuss and propose improvements based on the same data.

Furthermore, data accumulated through DX can be used for prediction and optimization with AI and advanced analytics. In the future, combining people’s location data with other data (equipment operation status, weather data, etc.) may enable advanced site management such as predictive detection of risk signs and automated work planning. The attitude of "moving the site based on data" fostered by on-site DX is transforming the experience- and intuition-dependent management style into a new conventional wisdom.

Key Points and Precautions When Implementing

When introducing visualization of people’s locations at a site, there are several key points and precautions to keep in mind.

First, gaining site consensus and clarifying objectives is important. While acquiring location information is convenient, workers may feel uneasy or resistant, worrying they are being "monitored." Therefore, it is essential to fully explain the purpose of the system before implementation and obtain employees’ understanding and consent. Emphasize that it is not for "watching whether people are slacking off" but to "ensure everyone can work safely and efficiently," and proceed while incorporating on-site voices.

On the technical side, choose positioning methods appropriate to the environment. Outdoor-dominant sites can use GPS or cellular signals, while indoor sites require combinations such as BLE beacons, UWB, or Wi‑Fi positioning depending on radio conditions. Select the optimal system considering site area, structure, and the presence of radio interference. Also consider hardware durability and battery life. If attaching to helmets, devices should be lightweight and not interfere with work; in explosive areas, use explosion-proof devices—designs must match the site environment.

Creating a framework for data utilization is also important. Don’t be satisfied with just collecting and visualizing location information—how you analyze it and turn it into improvements is the key to success. Regularly review heat maps and activity logs, and monitor KPIs (for example, reduction in travel distance, shortened response times). By making layout changes or rule improvements as needed, you can maximize the benefits of visualization.

Finally, do not forget to consider privacy and security. Handle and store acquired data carefully and implement measures to prevent unauthorized leaks or inappropriate use. Also, clarify the scope and rules of data collection so employees are not monitored during breaks or outside working hours, maintaining trust.

New Technology to Further Advance On-site DX: Simple Surveying with LRTK

Visualizing people’s locations is a major step in on-site DX, but digital technology use does not stop there. On-site needs are growing not only for "who is where now" but also for "quickly digitizing the site itself." Surveying tasks such as measuring terrain elevation differences or checking dimensions of completed structures traditionally required specialist surveyors and expensive equipment. However, recently, by using a technology called LRTK, simple surveying (position measurement) can be done with just a smartphone and a small device.

LRTK is a next-generation RTK positioning device that can be attached to a smartphone, making it easy to use the high-precision Real-Time Kinematic positioning technology. Traditional GPS had errors on the order of several meters (several ft), but using RTK allows position measurement with centimeter-level accuracy (half-inch accuracy). By utilizing simple surveying with LRTK, you can instantly record coordinates and heights of arbitrary points on site and reflect them in drawings and maps. For example, you can measure embankment or excavation volumes in civil engineering on the spot, or precisely record the positions of pipes and equipment inside buildings—tasks that previously required specialized surveying equipment can now be done without it.

This LRTK positioning technology can become a powerful tool to further advance on-site DX. Just as visualizing people’s locations digitizes the movement of "people," LRTK allows rapid digitization of "things" and "terrain." This makes it possible to comprehensively collect digital information about what is happening on-site and manage the site more holistically. Introducing simple surveying can also enable insourcing of surveying work that was previously outsourced, leading to cost reductions and shorter lead times. In on-site DX efforts, be sure to pay attention to new technologies like LRTK that digitize not only people’s movements but the space itself.
