How DJI Dock 3 Is Speeding Up Nigeria's 700km Coastal Highway Survey

Nigeria's Lagos to Calabar Coastal Highway is one of the largest road projects on the African continent, and surveying it with people on foot was never going to keep pace with construction. A case study video published by DJI Enterprise on 29 July 2026 explains how the construction team turned to the DJI Dock 3 to get survey data from remote sections of the route in near real time, without sending a pilot on a three hour drive every time management asked for a progress report. This article draws on the team's own account to explain what changed and why it matters for any long linear project.

The Scale Of The Coastal Highway Project

The Lagos to Calabar Coastal Highway runs roughly 700 kilometres along Nigeria's Atlantic coast from Victoria Island in Lagos to Calabar in Cross River State, crossing Ogun, Ondo, Edo, Delta, Bayelsa, Rivers and Akwa Ibom along the way. Construction began in March 2024 under Hitech Construction Company, with the first 30 kilometre section formally opened in May 2025 and completion of the full route planned over an eight year programme.

The terrain is the difficulty. The alignment passes through wetlands, mangroves and Niger Delta swamp forest, where access on foot is slow and often unsafe. For a survey team, that means long days covering short distances, and for management it means waiting days for the data that decides where the next section is built.

Why Traditional Surveying Could Not Keep Up

In the video the team is candid about the problem. Road construction depends on accurate, current ground data, and the traditional survey approach was not delivering it fast enough. Their survey crews on foot were covering between two and six kilometres a day, which on a 700 kilometre alignment is a bottleneck no amount of overtime fixes.

The second problem was distance. Site management regularly wanted reports as quickly as possible from sections where no drone pilot was present. Sending a pilot meant a drive of three or four hours before a single image was captured, and the same again to get back. Real time information, in the team's words, was the major issue.

What The DJI Dock 3 Changed On Site

The DJI Dock 3 is a weatherproof base station that houses, charges and launches a DJI Matrice 4D or Matrice 4TD aircraft on a schedule or on demand, with missions planned and monitored remotely through DJI FlightHub 2. Once installed on a section of the route, it flies survey missions without anyone on site, uploads the data automatically and is ready to fly again after a charging cycle of around 30 minutes.

For the highway team that solved both problems at once. As the team puts it, the traditional survey crew is still walking their two to six kilometres while the drone has already covered more, and when management wants a report from a distant section, the dock simply flies it. There is no longer a need to send a pilot on a long drive to capture what a scheduled mission captures on its own.

The team also highlights safety. Every kilometre a drone surveys from the air is a kilometre a crew does not walk through swamp forest or alongside live construction plant, which makes automated capture as much a welfare decision as an efficiency one.

Training From Aerosmart Made The Data Usable

Hardware alone did not get the team there. They invited Aerosmart, a DJI Enterprise dealer operating across Africa and the Middle East, to come to site and show them how the dock should be set up and how the data should be processed. The team describes going into the field with the Aerosmart engineers, learning the processing workflow and coming away with accurate data that aligned with what the project needed.

That knowledge did not stay with the people who attended. The team says it has been passed on to every drone pilot in the organisation, which is the difference between one successful demonstration and a capability the project can rely on for years.

Why The Matrice 4D Suits Linear Survey Work

The aircraft inside the Dock 3 is built for this job. The DJI Matrice 4D carries a 20MP wide angle camera alongside 48MP telephoto cameras, supports RTK positioning for survey grade accuracy and flies for up to 54 minutes on a charge, which is enough to cover a long stretch of alignment in a single mission. The Matrice 4TD adds a thermal sensor for night operations and security patrols.

Because the dock is IP56 rated and designed for permanent outdoor installation, it can be placed at intervals along a route and moved forward as construction advances. Each dock becomes a fixed survey station that reports to FlightHub 2, giving a project manager in Lagos the same picture of a site 400 kilometres away that they have of the one outside the window.

What UK Infrastructure Teams Can Take From This

The scale is Nigerian but the lesson travels. Any linear asset, from a new road or rail alignment to a pipeline corridor, a flood defence or a long stretch of highway maintenance, shares the same shape of problem. Progress needs to be measured regularly along a route that is long, awkward to access and far from the office.

Dock based operations turn that into a scheduled, repeatable capture that lands in the cloud before the morning meeting. In the UK the enabling piece is regulatory rather than technical, and the Matrice 4D series already holds C6 class marking and SAIL III OSO declarations that support automated and BVLOS operations under a suitable authorisation.

FAQs

How long is the Lagos to Calabar Coastal Highway?

The Lagos to Calabar Coastal Highway is planned at approximately 700 kilometres, running from Victoria Island in Lagos to Calabar in Cross River State. Construction started in March 2024 and the first 30 kilometre section opened in May 2025.

What is a drone in a box system?

A drone in a box system is a base station that stores, charges and launches a drone automatically. The DJI Dock 3 is one example, flying the Matrice 4D or 4TD on scheduled or on demand missions that are planned and monitored remotely through DJI FlightHub 2.

How far can DJI Dock 3 operate from the dock?

DJI Dock 3 supports an operating radius of up to 10 kilometres from the dock in ideal conditions, with actual range depending on the transmission environment, regulatory approvals and the mission profile. On a linear project docks can be positioned along the route to cover the full alignment.

Can drones replace traditional surveying?

Drones do not replace control surveys or the surveyor's judgement, but they replace the walking. A dock based drone captures a section in minutes that a crew would spend a day covering on foot, and the surveyor's time moves to checking, processing and interpreting the data.

Final Thoughts

The Nigerian coastal highway team started with a survey crew covering a few kilometres a day and a management team waiting on reports from sites hours away. With DJI Dock 3, Matrice 4D and a workflow learned from Aerosmart, they now get accurate data from remote sections on demand, keep crews out of difficult terrain and pass the capability on to every pilot they have. For any organisation managing a long asset, that is the model to study.
