Strengthening Team Collaboration with Cloud Syncing of GPS Data! The Secret to Connecting Field Sites and Offices

Transforming Field Operations with GPS

At construction and surveying sites, the adoption of the latest technologies is dramatically transforming operations. Among these, the use of GPS (satellite positioning) technology is revolutionizing how fieldwork is carried out.

Surveying and construction management that once relied on craftsmen’s intuition and paper drawings are being digitized through the precise positioning information provided by GPS, enabling greater efficiency and labor savings. Initiatives such as i-Construction promoted by the Ministry of Land, Infrastructure, Transport and Tourism encourage ICT adoption on sites, and the use of drone surveying and GPS positioning has become an indispensable trend in the construction industry and local governments.

GPS enables high-precision surveying at the centimeter level (half-inch accuracy), and tasks that once required several people can now often be completed by a single person in a short time. For example, using a method called real-time kinematic (RTK), positioning data from multiple satellites can be combined to obtain accurate coordinates on site instantly, dramatically improving the efficiency of setting out for bridges and roads. Traditional surveying with a total station required multiple people to set up or guide targets, but with RTK-GPS a single operator carrying a positioning unit can perform layout tasks, enabling one-person surveying on some sites. Furthermore, RTK-GPS can acquire elevation information on site in addition to latitude and longitude, so elevation data that used to be measured separately by leveling can now be obtained simultaneously. These technological advances have made precise three-dimensional surveys based on official reference coordinate systems much more efficient.

High-precision GPS equipment itself has also become smaller and lighter in recent years, and adoption costs are trending downward. Where once large stationary units were the norm, there are now handheld types and GNSS receivers that link with smartphones, making them easy to carry to the field. Combined with these technological evolutions, the DX of field operations using GPS is accelerating further.

Additionally, because position information acquired by GPS is obtained as absolute coordinates in public coordinate systems, field-measured data can be overlaid on maps instantly. This is advantageous for using survey results in GIS systems or sharing data with other departments, maximizing the value of field data.

Amid chronic labor shortages and an aging workforce of technicians, labor-saving technologies like GPS surveying are a trump card for maintaining field productivity. Survey tasks that once required advanced expertise can now be performed by younger or fewer staff thanks to user-friendly GPS equipment and software, contributing to organizational workstyle reform.

Operational Efficiency Brought by Cloud Syncing of Positioning Data

A key factor in further advancing field DX using GPS is “cloud syncing of positioning data.” Uploading and sharing position information and survey data acquired on site to the cloud eliminates time lags between the field and the office. Because measurement results and progress status are distributed to all stakeholders immediately, the time spent on data handoff and manual entry can be significantly reduced.

Traditionally, field staff would return to the office with USB drives or paper records, which office staff then had to enter manually. With cloud syncing, data from field terminals is automatically consolidated into a database, eliminating intermediate handoff processes. This not only saves time but also helps prevent human errors such as transcription mistakes and missed communications.

For example, when conducting large-area topographic surveys, using an RTK-capable drone can produce a detailed 3D model within a single day. If that data is shared immediately via the cloud, office colleagues can already review the results by the time surveyors return from the field. The conventional workflow that once took several days from surveying to analysis and drafting is dramatically accelerated.

Moreover, raw data stored in the cloud can be automatically processed into drawings or 3D models. As a result, office engineers can use the field-uploaded data immediately for analysis and review, greatly shortening decision-making lead times. Centralized accumulation of data in the cloud also allows past records to be referenced at any time, preventing loss of information due to misplaced paper documents or scattered files and contributing to improved operational efficiency through paperless workflows.

Strengthening Team Collaboration through Data Sharing

Data sharing via the cloud dramatically strengthens collaboration within teams. From field workers to office engineers and management, everyone can access the same up-to-date information, creating a “shared understanding” without discrepancies among members. Once information is consolidated in the cloud it becomes the single source of the latest data, eliminating situations like “not knowing which drawing is the latest” or “the field and office are looking at different materials.” Because decisions and tasks proceed based on shared data rather than fragmented information held by individuals, miscommunications between the field and the office are reduced.

For example, if survey data is immediately viewable in the cloud, design personnel can start revising drawings while fieldwork is still in progress. It also makes it easier to share data with subcontractors or other departments as needed, so all stakeholders can literally collaborate while looking at the same map. This transparency and immediate sharing of data break down barriers inside and outside the organization and foster a sense of unity across the team.

Real-time data sharing also enables remote support, where experienced office engineers can review positioning data and photos from the field and provide advice. Even without everyone being physically on site, sharing expertise via the cloud can harness the whole team’s capabilities—an important advantage.

Furthermore, surveying data consolidated in the cloud can be easily combined with 3D models such as BIM/CIM (Building/Construction Information Modeling), serving as a consistent information-sharing backbone across design, construction, and maintenance stages. This smoothes data flows throughout projects and strengthens cross-departmental collaboration.

The Importance of Real-Time Coordination between Office and Field

In construction work and disaster response, whether the office and the field can coordinate in real time greatly affects outcomes. With real-time information exchange, the office can respond immediately to changes in field conditions, and the field can promptly receive instructions and the latest drawings from the office. Delays in information transmission not only reduce productivity but can also lead to rework based on outdated information and pose safety risks.

For example, if a surveying team discovers inconsistencies with design drawings on site, they can upload photos and notes with positional information to the cloud on the spot. The office can review them instantly and make decisions on countermeasures or design corrections. Conversely, if the office identifies a planning change or an error, updated information can be sent immediately to field crews, who can then proceed with tasks according to the new instructions. This two-way, real-time feedback maintains a constantly synchronized state between field and office.

Sharing progress in real time also makes it possible to immediately grasp whether field work is ahead of or behind schedule, allowing proactive adjustments to schedules and resource allocation. This reduces unnecessary waiting times and contributes to smooth overall project execution.

Real-time coordination is also useful for safety management. Continuously tracking worker positions via GPS enables rapid safety checks and dispatch of rescue teams in accidents or disasters. In fact, the Japan Ground Self-Defense Force has implemented a system that allows personnel to instantly share photos of disaster sites taken on smartphones with GPS location information on maps, improving rescue efficiency through close information sharing with command posts.

Case Studies (Local Governments and Disaster Sites)

The benefits of GPS cloud syncing have already been demonstrated in several local governments and field sites. Some municipalities use it for routine infrastructure inspections. For example, if a patrol officer discovers a faulty streetlight, taking a photo with GPS location and saving it to the cloud allows the office to immediately identify the exact failure location. Based on that data, repair arrangements can be made swiftly, significantly improving responsiveness compared to the days when teams relied on paper logs or individual memory.

Maintaining a cloud-based asset database with location information also aids long-term, planned maintenance and preventive care.

In disaster sites, municipalities are beginning to introduce surveying systems that combine smartphones and high-precision GPS. For example, Fukui City was quick to introduce in 2023 a surveying system (LRTK) that uses iPhones and high-precision GNSS receivers for disaster recovery field surveys. Because staff can start surveying and recording with their smartphones as soon as they find damaged areas, it has become possible to collect the data needed for early recovery quickly. Performing tasks in-house that were previously outsourced to external surveyors has also contributed to cost reduction. Visualizing damage at centimeter-level accuracy (half-inch accuracy) accelerated decision-making and greatly contributed to ensuring residents’ safety and security.

In the private construction sector, GPS-based construction management is also spreading. Cases are increasing in which GNSS-equipped construction machinery measures excavation and embankment shapes in real time, and worker position information is used for safety management. Visualizing overall progress in the cloud strengthens coordination among construction stakeholders.

Some municipalities also equip snowplows and patrol vehicles with GPS terminals and centrally manage location information in the cloud. Even at sites with many moving vehicles, headquarters screens allow real-time monitoring of each vehicle’s current location and operation history, enabling efficient and accurate instructions and achieving maximum results with limited personnel.

Challenges for Adoption and Approaches to Solutions

When introducing GPS cloud-sync systems to the field, several issues can arise during the planning stage. However, with appropriate approaches to each, smooth adoption and stabilization are possible. Below are common issues and example solutions.

• Initial implementation cost: Implementation costs can be a concern, but the initial burden can be reduced by using national subsidies or phased implementation.

• IT literacy and operational proficiency: Concerns that new systems are difficult can be addressed by choosing intuitive smartphone-app-style tools and providing pre-introduction training.

• Communication environment: Real-time syncing can be difficult in areas without coverage such as mountainous regions, but using systems with offline recording features or selecting equipment compatible with Japan’s quasi-zenith satellite Michibiki (CLAS) allows acquisition of high-precision data in signal-poor sites to be synced later.

• Integration with existing systems: If compatibility with existing CAD or GIS is a concern, selecting solutions with survey data export functions or API integration enables smooth incorporation into existing workflows.

• Internal resistance: If there is resistance to changing field practices, starting with a small pilot implementation to demonstrate effects and sharing that success internally can help gain acceptance.

• Data security: Concerns about entrusting important data to the cloud can be mitigated by choosing reliable services and enforcing measures such as encryption and strict access controls.

With appropriate countermeasures in advance, organizations can fully reap the benefits of cloud syncing of GPS data and achieve successful adoption.

Finally: A New Option for Simple Surveying with LRTK

As described in this article, cloud syncing of GPS data greatly enhances coordination between field and office, improving operational efficiency, accuracy, and rapid response capabilities. The shift to such digital workflows is progressing in the construction industry and among local governments, contributing to productivity improvements, error reduction, and enhanced safety.

Among these developments, a notable new option for simple surveying is LRTK. LRTK combines a smartphone with a compact high-precision GNSS receiver to enable centimeter-level accuracy (half-inch accuracy) surveying that anyone can perform easily. It does not require large traditional equipment and allows quick surveying with intuitive operation even by non-specialists. Moreover, coordinate data and photos with location information are automatically synced to the cloud, enabling instant sharing between field and office. On the LRTK cloud service, coordinate points and photos acquired on site are plotted on a map interface and managed centrally, and they can be viewed from an office PC. Data can be downloaded for import into CAD software as needed, or secure share links can be issued to remote departments and subcontractors, making it easy to share the latest data. Using LRTK not only simplifies surveying tasks but also realizes seamless information sharing among teams as discussed above.

LRTK, which effortlessly links field and office, is therefore an attractive option for decision-makers considering strengthening team collaboration through GPS utilization. By leveraging advanced tools, organizations can ride the wave of DX in the industry and build a structure in which team members in both the field and the office work together cohesively. This will not only improve daily project productivity and accuracy but also enhance rapid response capabilities when needed.

Satellite positioning technologies and cloud platforms will continue to evolve. For example, using AR (augmented reality) on site to visualize the locations of underground buried objects or employing AI analysis to automatically detect anomalies from surveying data are becoming realistic uses. Introducing solutions like LRTK ahead of these trends lays the groundwork for future efficiency gains and advanced data utilization. Starting initiatives now to connect field and office is expected to further advance DX across the organization.
