Is a qualification required for drone surveying? This is the first question that on-site personnel and those in charge of implementation encounter, but to conclude, you cannot say it is uniformly "mandatory" at all times. The qualification to fly an unmanned aircraft and the qualification to establish survey results are separate, and procurement conditions also vary depending on the type of project. The Ministry of Land, Infrastructure, Transport and Tourism has stated clearly that obtaining an unmanned aircraft operator skill certificate itself is not a constant mandatory requirement for flight, while it also advises that aircraft weighing 100 g or more must be registered, and that permissions or approvals may be required depending on the airspace and flight methods.

What's even more complicated is that the term "drone surveying" covers a wide range of activities. Whether it's capturing pre-development terrain, documenting construction progress, performing as-built checks, producing deliverables for government agencies, or acquiring point clouds for earthwork volume calculations, different purposes require different levels of accuracy and different responsibilities.

The Geospatial Information Authority of Japan (GSI) indicates that many surveys carried out by national and local governments fall under public surveying, and public surveys involve more stringent procedures and organizational requirements. In other words, readers who search for "qualifications" really want to know not simply whether a pilot license is required, but what the necessary conditions are for their particular project.

In practice, confusing these makes it easy to make wrong judgments. For example, if you proceed based only on information such as "apparently you can fly without a national license," you may omit checking the flight plan and permission approvals. Conversely, if you assume that "as long as you have a piloting license, surveying is valid," you may omit verifying the accuracy of the results and organizing matters under surveying law. What is important for the person in charge is not to lump qualifications together under a single name, but to organize them into three categories: flight rules, surveying rules, and order conditions. Simply being able to do this will make internal coordination and the selection of subcontractors much easier.

Reasons Why the "Qualifications" for Drone Surveying Are Hard to Understand

First, it’s important to understand that the term "qualifications" as used on site has at least three meanings. The first is the regulatory qualifications and procedures for safely operating unmanned aircraft. The second is the requirements under the Survey Act, such as licensed surveyors, assistant surveyors, and surveyor business registration, for handling survey results. The third is the internal standards, performance requirements, report formats, and reproducible quality control systems that prime contractors or clients may independently require. When readers ask, "Do I need qualifications?", these three meanings are usually mixed together.

According to the Ministry of Land, Infrastructure, Transport and Tourism’s guidance, the unmanned aircraft operator competency certificate is not a system that is always mandatory. On the other hand, when flying an unmanned aircraft of 100 g (3.5 oz) or more outdoors, aircraft registration is required, and depending on the airspace and manner of flight, prior permission or approval may be necessary. In addition, when flying under permission or approval, notification of the flight plan and the preparation of a flight log are also required. In other words, saying “no qualification is required” is a rather crude summary, and in practice you must confirm multiple obligations such as registration, permission, approval, notification, and record keeping.

On the other hand, the Survey Act is organized differently. Materials from the Geospatial Information Authority of Japan state that technicians engaged in fundamental surveys or public surveys must be registered surveyors or assistant surveyors, and that anyone who intends to carry on surveying business must be registered as a surveying contractor. In other words, the qualifications for flight and those for surveying are aimed at fundamentally different institutional purposes. If you understand that the former is a system for aviation safety while the latter is a system to support the accuracy of survey results and their use by society, it becomes easier to grasp the overall picture.

That is precisely why the person in charge must first clarify “what to produce” and “how the deliverables will be used.” Whether it is simply acquiring progress photos, a point cloud for earthwork volume estimation, a terrain model for as-built verification or design review, or deliverables to be submitted to government authorities, the qualifications and organizational structure that need to be checked will differ. If you proceed by merely “finding someone who can pilot” while leaving this unclear, problems such as unusable outputs, the need for re-flights, and an inability to fulfill accountability are likely to arise.

Point 1: Flight qualifications and surveying qualifications are separate

One key point is that the qualification to fly a drone and the qualification to conduct a survey are separate. Under the unmanned aircraft regulatory system, the focus is on whether you can operate safely in accordance with flight rules. The Ministry of Land, Infrastructure, Transport and Tourism lists, as representative examples requiring prior permission or approval, flights over densely populated areas, night flights, flights beyond visual line of sight, flights that cannot maintain a distance of 30 m (98.4 ft) or more from people or property, flights over event sites, the transport of dangerous goods, and dropping objects. In urban surveys, confined sites, and areas with many obstacles, these conditions are easily encountered, so even for surveying projects, sorting out the flight plan takes priority.

On the other hand, from a surveying perspective, the coordinates of the deliverables, their accuracy, verification methods, and lines of responsibility are questioned. The Geospatial Information Authority of Japan requires that surveying planning organizations and surveying operational organizations comply with aviation laws, related guidelines, and flight rules when conducting public surveys, but at the same time there is also a framework on the public surveying side covering procedures, work regulations, implementation plans, and deliverable reviews. In other words, the ability to fly is not equivalent to the suitability of the results for surveying. Even if the pilot is skilled, if ground reference standards and accuracy verification are insufficient, the reliability of the survey results cannot be guaranteed.

A common misunderstanding here is the view that “if you can fly without a national qualification, then completing a private training course should be sufficient.” Indeed, the Ministry of Land, Infrastructure, Transport and Tourism has indicated that a skill certificate is not always required. However, this does not mean “no preparation is necessary,” nor does a private course completion certificate carry the same legal weight as a national qualification. Moreover, recent administrative practice has disclosed that the simplification of application procedures concerning private skill certifications, which had been used in some cases in the past, was abolished by the amendment that came into effect on December 18, 2025. Those responsible should not simply rely on old explanatory materials or past practices and must confirm matters under the latest rules.

There is also a system whereby a person who has obtained a pilot skills certificate operating an unmanned aircraft that has received aircraft certification can make permissions or approvals unnecessary for certain specified flights. However, this does not mean unrestricted freedom in all cases. It is premised on safety measures such as access control and the preparation of flight manuals, and the scope is limited. Therefore, you should not judge only by whether someone holds the qualification; you must also examine which flight categories the qualification covers and which procedures it allows to be omitted, otherwise you will not be able to make a correct practical judgment.

Put from the person in charge's perspective, when checking subcontractors or internal operations, the first question you should ask is not just "Do you have pilot qualifications?". You need to confirm, including operational planning: "Which airspace do you plan to operate in?", "Will there be night operations or flights beyond visual line of sight?", "Will the operation involve densely populated areas?", "How will permits and approvals be arranged?", and "How will flight-plan notifications and records be managed?". Only after confirming these aspects up to operational planning will the flight team's structure become clear. If this remains ambiguous and you proceed, conditions may only become clear the day before on site, resulting in situations where you cannot fly, must change plans, or must reduce the scope of deliverables.

Point 2: Requirements Are One Level Higher for Public Surveying

The second point is that the required conditions change significantly depending on whether a project falls under public surveying. In the Geospatial Information Authority of Japan’s 2026 edition of the manual, it is indicated that most surveys conducted by the national government, local public bodies, and similar entities qualify as public surveying. Many tasks related to social infrastructure fall under this, including roads, rivers, urban areas, land readjustment, land improvement, and the development of basic map information. If the person in charge handles government agency projects, projects involving subsidies, or deliverables that connect to public works, it is safer to assume that you should first determine whether the work is a public survey.

In public surveying, the roles of surveyors and assistant surveyors are clearly defined. An excerpt of the Survey Act included in the Geospatial Information Authority of Japan’s guide states that those who engage in basic surveys or public surveys as technicians must be registered surveyors or assistant surveyors, that surveyors prepare or carry out plans related to surveying, and that assistant surveyors engage in surveying in accordance with plans prepared by surveyors. It further indicates that anyone who intends to operate a surveying business must be registered as a surveying contractor. At this stage, simply securing personnel who can operate equipment is not enough; an organizational structure that complies with the Survey Act is required.

Additionally, the guidance on implementation plans for public surveying states quite specifically that the planner responsible for surveying must be a licensed surveyor, and that the surveying organization contracted to carry out public surveys must be a surveying business registered under the Survey Act. In other words, using drones in public surveying is not simply a matter of adopting new equipment. A drone is one means of data acquisition within a workflow in which a surveyor is involved in planning, a registered surveying business assumes responsibility, and accuracy is ensured through work procedures and the implementation plan.

Therefore, when a person in charge of a public project verifies the "drone surveying qualifications," checking only whether the operator has a competency certificate is insufficient. What should be confirmed is whether the involvement of a licensed surveyor is clear, whether the surveying contractor is properly registered, how these requirements are incorporated into work procedures and implementation plans, and how deliverables will be reviewed and their accuracy verified. If these points are skipped, then even if flights can be conducted safely, the procedures and quality required for public surveying may not be met. In public surveying, both flight safety and the accuracy of survey results must be managed simultaneously.

Furthermore, the Geospatial Information Authority of Japan requests that, for public surveying using unmanned aircraft, survey-planning organizations and survey-operating organizations thoroughly consult with each other while complying with aviation laws, related guidelines, and flight rules. This is because site conditions, safety, required accuracy, equipment used, and work methods differ from case to case. For those responsible, the closer a project is to a public survey, the fewer failures there will be if you organize “under what system, according to which regulations, and how accuracy will be assured” before deciding “who will fly.”

Point 3: You can't categorically say that qualifications aren't required even for private projects

The third point is not to dismiss a private-sector project as “no qualification required.” Indeed, under the Ministry of Land, Infrastructure, Transport and Tourism’s system, since the Unmanned Aircraft Operator Skill Certificate is not always mandatory, it isn’t a simple matter that you can do nothing on a private site simply because you lack a national qualification. However, there are separate rules such as aircraft registration for aircraft of 100 g or more, permissions and approvals depending on flight conditions, flight plan notifications, and accident reporting. In other words, the need for a national qualification and the need to comply with laws and regulations are not the same. If you confuse them, it’s easy to fall into the misunderstanding that “because a license isn’t required, no preparation is necessary.”

In private-sector projects, what matters is how the deliverables will be used. For example, there are cases where they are used only as reference materials—progress checks for internal sharing, rough terrain assessment, or visualizations for sales proposals—and cases where they are used in ways close to quantity verification for payment, earthwork volume assessment, overlaying with design, or construction decision-making; the reproducibility required is completely different. The closer you get to the latter, the more important quality control becomes: how coordinates are taken, the approach to control points and validation points, checking methods, consistency when re‑flying, and how reports are retained, and as a result the involvement of qualified personnel and the establishment of a surveying framework realistically become necessary.

Also, because private-sector projects are less constrained by standardized procedures than public surveying, there are many situations where the person in charge must establish their own standards. For example: which coordinate system the deliverables should use, what level of vertical accuracy is required, how many ground control/check points to collect, which items to use for quality checks on point clouds and orthophotos, and how to handle cases that require re-flights due to poor site conditions. If you simply "hire a company with the proper qualifications" without deciding these things, interpretations of the results are likely to vary later. Qualifications are one reassurance, but they are not a magic phrase that automatically guarantees quality.

Especially in urban areas, around infrastructure, and on tight sites, the difficulty of flight rules increases dramatically: over densely populated areas, beyond-visual-line-of-sight flights, distances to people and property, areas around airports, height restrictions, and so on. It is not uncommon for organizing flight requirements to become a bottleneck before the difficulty of the surveying itself. What on-site personnel truly want to avoid is being unable to fly on the scheduled day and, even if they can fly, having results that cannot be used. To avoid those two outcomes, even for private projects you should not judge solely by whether someone has qualifications; you must confirm the flight conditions together with the intended use of the results.

Moreover, in private-sector projects, it is important to be aware that the rule of thumb "this used to be accepted" tends to persist. Because regulations and review procedures are updated, simplifications that were usable in the past are not necessarily still valid. If the person responsible can communicate with contractors based on the latest information, unnecessary misunderstandings can be reduced. Conversely, proceeding with outdated explanations causes discrepancies in application methods, required documents, and in how one assumes responsibility for explanations. Drone surveying is a field where equipment evolution is notable, but what makes a practical difference is whether operations can be reexamined with regulatory updates in mind.

Point 4: Evaluate the person in charge by their operational structure rather than by the qualification name

The fourth point is that what the person in charge should evaluate is the operational framework rather than the qualification titles themselves. Naturally, it is a given that the necessary qualifications and registrations are in place. However, what actually determines success or failure is the procedures used to enter the site, how accuracy is managed, and whether the deliverables can be documented in a way that makes the results explainable. The Geospatial Information Authority of Japan’s emphasis on work procedures, implementation plans, and results review in public surveying reflects a demand for reproducible quality control rather than one-off technical skill.

The first thing the person in charge should confirm is what the results will be used for. Whether they are for internal reference, for design review, for decisions about as-built conditions or maintenance management, or for formal submission to the client and stakeholders will change the required arrangements. The more critical the intended use, the more important the involvement of a surveyor, responsibility as a registered operator, accuracy verification, reports, flight records, and the establishment of reproduction procedures become. The more the person in charge can articulate this up front, the more they can reduce rework in later stages.

Next, what matters is what kind of flight conditions the site presents. Is it in an urban area or the suburbs, are there height restrictions, can you maintain sufficient distance from people and structures, can flights be operated within visual line of sight, and is access control possible? These conditions determine the permits, approvals, and prior coordination required. If you commission work based only on whether qualifications exist, the schedule may be set with these issues insufficiently clarified, making it likely that constraints will surface just before arriving on site. Verifying qualifications is the entry point, but what is truly necessary is confirming an operations plan tailored to the site conditions.

Furthermore, it is essential to look at quality control from a surveying perspective. Which reference points or check points will be used, how will coordinates be handled, how will errors in point clouds and images be checked, and how will consistency be ensured when re‑flying on different days? A person who can clearly explain these matters understands not just how to "fly" but how to produce "usable deliverables." Conversely, even if they can explain the names of qualifications, if the flow of accuracy verification and the basis for the deliverables are vague, those responsible should be cautious.

Finally, what you should look at is how responsibility is handled. Who will provide explanations if something goes wrong, who decides on a re-flight, how will deficiencies in deliverables be remedied, and who is responsible for checking laws and procedures? Drone surveying may appear agile, but once its outputs are used in operations you cannot escape accountability. The person in charge should not be reassured by the name of a qualification alone; reviewing the organizational framework, procedures, records, and allocation of responsibilities is, in practice, the most realistic way to manage risk.

Summary

The answer to the question "Is a qualification required for drone surveying?" is, "The same qualification is not always mandatory, but the required conditions vary greatly depending on the nature of the project." While an unmanned aircraft pilot proficiency certificate is not always required, rules such as aircraft registration for aircraft weighing 100 g or more, permits and approvals depending on flight conditions, and flight plan notifications need to be observed. And for public surveying, requirements under the Survey Act—such as licensed surveyors and assistant surveyors, registration of surveying businesses, plans and work procedures, and result reviews—become important.

In short, the four points a person in charge should know are: treat flight qualifications and surveying qualifications separately; the required conditions change depending on whether it is a public survey; even in private projects, flight rules and quality control are indispensable; and ultimately, evaluate the operational system rather than the name of the qualification. Keeping these four points in mind lets you move beyond the superficial debate over whether someone “has a qualification or not” and make the essential judgment of whether the project can be executed safely, accurately, and as usable deliverables.

To make drone surveying truly usable in the field, it is important to establish operations that include not only aerial data acquisition but also ground-side coordinate checks and how to secure local reference points. If you want to streamline the entire workflow—from on-site positioning and photo records to point capture and sharing among stakeholders—combining an iPhone-mounted, high-precision GNSS positioning device such as LRTK can be effective. By capturing broadly with drones and ensuring the necessary points on the ground, you can more easily improve the reproducibility of surveying work and the speed of on-site decision making.
