We are all aware of the scale of disaster that Hurricane Melissa visited on the southwestern parts of Jamaica late last year: 45 people dead, 1,5million displaced and about $8,8billion worth of property destroyed.

“Hurricane Melissa left deep scars across Jamaica, with women and girls bearing the heaviest burden of recovery,” said Jonathan Arogeti, CARE’s Caribbean Humanitarian Response Lead.

“Local organisations, especially women-led groups, have been on the frontlines of response and recovery, driving positive and lasting impacts despite significant challenges. This historic storm underscores the urgent need to invest in locally-led preparedness now, so communities are less vulnerable when the next storm strikes.”

And one of the organisations that led these recovery efforts was Jamaica Flying labs, part of the Flying Labs Network of drone, robotics and related technology start-ups in the global south created for the sole purpose of pioneering the search for local solutions to local problems.

The story of Jamaica Flying Labs’ disaster response efforts in the aftermath of the hurricane is told below. 

 When Hurricane Melissa made landfall in southwestern Jamaica near New Hope on October 28, 2025, it wasn’t just a storm; it was a record-shattering atmospheric assault.

With sustained winds of 185 miles per hour, the Category 5 hurricane — the strongest ever recorded to hit the island country — unleashed a violent torrential downpour that threatened to stall lifesaving relief efforts.

Power outages plunged 77 percent of the country into darkness, and communications infrastructure destroyed just as the landscape was being pummelled into unrecognisable fragments by four-metre storm surges and catastrophic winds.

But they do say brilliant captains only prove their worth in stormy waters; in the wake of such devastation, a new hero emerged, with an innovative paradigm of disaster response.

For the first time in Jamaica, external agencies and foreigners did not lead a large-scale international relief effort but were instead locally led and globally supported. Leading this digital vanguard was Jamaica Flying Labs (JFL), a member of a global network of local drone and mapping labs spanning 41 countries.

Jamaica Flying Labs is a small but impactful nonprofit start-up that found itself tasked by the government with a massive responsibility: coordinating the entire national drone response.

The organisation’s founder Valrie Grant, was flying to a United Nations (UN) conference in Chile when the news of the scale of the task ahead began to set in.

During a hastily assembled video conference with Jamaica’s Office of Disaster Preparedness and Emergency Management (ODPEM) and the National Emergency Response Geographic Information Systems Team, Grant learned that her start-up had been granted the onerous responsibility of leading the drone-based geospatial mapping for damage assessment.

To ensure the safety of low-flying relief helicopters and a unified airspace, the government even placed a temporary blanket ban on all unauthorised drone flights across the island, funnelling aerial reconnaissance through JFL.

JFL has been building up its technology and teams of volunteers since it was founded in 2018. But, for any Flying Labs franchise, this was the biggest task undertaken since the Nepal earthquakes of April 2015 that saw the birth of the first ever Flying Labs start-up.

It could even dwarf the response efforts undertaken by Zimbabwe Flying Labs, which sent drones to the east of the country to map the trail of destruction left by Cyclone Idai in 2019.

“We knew we were going to be part of it,” but “we didn’t recognise that we would be the ones coordinating the entire effort,” Grant said.

Having followed the events happening in that part of the country from a distance, she had seen some videos of the damage, but Grant was not prepared for what was waiting for her and her team when they landed at the actual scene.

“We’ve never seen anything like that,” she said. In some places, “my country was unrecognisable.”

Layered Intelligence: HOT, MapAction, and the Power of the Crowd

Even before Melissa reached the coast, the effort to measure the damage was in motion. JFL partnered with the Humanitarian OpenStreetMap Team (HOT) to launch ChatMap, an open-source tool that transformed WhatsApp messages and voice notes into geolocated data.

Despite widespread power outages, over 2,000 Jamaicans used the tool to report flooding, landslides, and road blockages in real time.

This “community-reported” layer was supplemented by a massive remote mapping effort. Through HOT’s Tasking Manager, 247 volunteer mappers from around the world scrutinised high-resolution satellite imagery to identify damaged buildings across Jamaica and neighbouring Cuba.

Satellite imagery, however, has its limits — especially when it comes to providing imagery with the right resolution for areas under cloud cover.

To pierce the veil, JFL deployed a fleet of drones, logging over 300 hours of flight time across 320 communities.

“With drones, we are able to capture higher-fidelity, more granular data at the community level pictures garnered via satellites,” Grant said.

For much of the response, JFL fielded about five drone teams. Each team, composed of a pilot and a spotter, was assigned to capture data within pre-established nine square-kilometre grids, with priority areas set by the National Emergency Response Geographic Information Systems Team coordinator.

After each roughly 20-minute flight, the teams transferred the data to memory cards for later uploading to the cloud.

As people in the hardest-hit townships searched for temporary shelter and began to pick up the pieces, the first priority for government GIS specialists was assessing damage to transportation networks.

Said Grant; “You need access in order to get into the communities so that people can remove debris from the road, clean the roadways, and make sure that ports were intact too.”

The Jamaica Public Service Company deployed its own separate drone-enabled GIS team to assess damage to power lines.

And while JFL’s drones provided the raw imagery, back in Kingston, the international charity MapAction arrived to turn that data into a strategic blueprint for survival.

For humanitarian planners, the chaos of a disaster zone is a logistical nightmare; MapAction’s role was to provide a common operating picture. Using data flowing in from other groups operating on the ground, MapAction volunteers produced critical “Who/What/Where” (3W) maps, which plotted the locations of eighteen different non-governmental organisations (NGOs) and UN agencies to ensure that food, water, and medical aid reached every corner of the island without duplicating efforts.

Alicia Edwards, principal director of Jamaica’s National Spatial Data Management Branch, underscored the importance of this work.

“When Hurricane Melissa struck Jamaica, maps became just as vital as manpower,” she said.

Combined with imagery from the ground and the skies, the National Emergency Operations Centre’s public dashboard provided a living picture of where the worst impact was and where help was being deployed.

As new data came in, the maps tracked hundreds of active shelters, integrated satellite imagery from the European Space Agency’s Copernicus Programme, and turned WhatsApp field reports into geospatial damage layers.

One particularly vital map produced by the team highlighted damaged potentially hazardous facilities — industrial sites, landfills, and quarries — allowing responders to identify secondary environmental threats while simultaneously mapping road damage to ensure aid trucks didn’t become stuck.

Following the Sun

The JFL model relied on a “follow the sun” processing strategy. As drone pilots in Jamaica finished their exhausting days in the field, they uploaded their data to a global network of sister Flying Labs.

But crucially, the JFL team was not alone in this, as the true objective of why the Flying Labs network was created in the first place. An army of experts from other labs in Panama, Brazil, Tanzania, India, and Senegal pounced on and processed the imagery as soon as it was available, generating orthomosaics and digital surface models that were ready for Jamaican decision-makers soon after.

Partnerships with two tech giants provided the digital infrastructure: Through its Disaster Response Program, Esri – a global market leader in geographic information system (GIS) software and location intelligence solutions – provided the ArcGIS Hub and ArcGIS Experience Builder applications used to assign pilots to specific 3×3-kilometre grids; it also helped establish image processing workflows in a low-bandwidth context.

Meanwhile, software giant Microsoft stepped in with Azure cloud storage and free consulting to handle the massive influx of imagery.

Drone manufacturers Wingtra and Skydio contributed both autonomous drone hardware as well as a handful of personnel to help cover the 900 square kilometres of the worst-affected disaster zones.

For Grant, the effort solidified a new approach to mitigating and responding to disasters, one built on local control and self-sustainability.

Leveraging technology, specifically drone technology, for more locally driven recovery efforts is at the heart of the Flying Labs mission.

Officially founded in 2015, the network of local innovation hubs equips its communities with the technology, skills, and connections helpful for solving social and environmental problems, often with drones.

Under the “inclusive networks” model — initiated by WeRobotics, the Geneva-based nonprofit behind the Flying Labs Network — each lab operates as an independent licensee, run by a local for-profit, nonprofit, or academic organisation.

By incubating and training local drone pilots and GIS analysts, the goal is to put mapping, remote sensing, and robotics in the hands of locals, instead of foreign companies and consultants who often parachute in with little local knowledge or interest in local stewardship.

Grant explained that JFL, alongside other units in Haiti and the Dominican Republic, is now seeding labs in other countries across the hurricane-prone Caribbean.

“Today it’s Jamaica; tomorrow it’s someplace else in the region,” she said.

And in Jamaica, JFL and others within and outside of government have been running a series of capacity-building and educational events across the country centred on community-led disaster awareness and response.

About a week before Melissa, Grant helped lead a stakeholder engagement workshop in a coastal community that suffers from frequent flooding.

“We literally shifted our collaborative learning project from that community into being a response template for Melissa,” she said.

“When we got that call, that shift was much simpler for us to make because we were already in that frame of mind.”

Friction on the Ground: Data Bottlenecks and Fiber Lines

Despite the high-tech coordination, the reality on the ground was often old school. Grant highlighted a significant technical bottleneck: the sheer volume of data.

A single three-kilometre grid could generate up to 10,000 images, totalling ten gigabytes of data. While the teams had Starlink satellite units for WiFI connectivity, the high density of users in the disaster zone degraded the service, making data uploads impossible from the field.

JFL had not bargained for that.

“We had bottlenecks in terms of the data upload,” she explained.

“I’ve now formed a partnership with a telecommunications company. We literally have a desk inside one of their offices uploading data.”

But all of that was after; at the time of the disaster, the connectivity problems meant mobile teams had to physically drive hard drives from the devastated western parts to a dedicated fibre-optic line in the capital, Kingston. On some days, drones would ferry the data back to base too.

Among the many lessons and reminders Grant drew from JFL’s frontline work was the importance of being adaptable.

“Even in terms of your workflows, you have to have that flexibility to recognize that theory and practice are two different things,” she said.

“That’s something that we take to heart, and we were able to pivot and to evolve things on the fly, building as we go, because we recognise what the moment called for.”

On the technical and social side, she’s seen many opportunities for improvement — not just in JFL’s internal processes, but also how to better feed data into the national response workflow.

Another lesson: Drone teams should have a seamless way to provide their own field reports as they collect imagery data, “so that the people who need it can get immediate help.”

The “Human Element” of the Drone

As drone teams gathered critical imagery, Grant saw how they were coping not only with technical challenges but also with the emotional weight of the work.

Unlike satellite imagery, which can feel detached, drone mapping is an intimate act. Pilots are physically present in the communities, witnessing the trauma of survivors firsthand.

“Being on the ground was a whole different experience,” she said.

On her first day in the field, she recalled encountering one woman who had lost her home and was living in her car. She watched neighbours put an injured man in a wheelbarrow and, with emergency services still unable to reach their town, push him to the hospital.

Sadly, he could not make it, as he died along the way.

“You recognise that they need to talk,” she said.

“Even my team — I now recognise what they were going through.”

To address stress among team members, Grant consulted an expert in resilience to help coordinate weekly check-ins and breathing exercises for volunteers.

“You just have to remind yourself, as I told the team, that even though we can’t do everything — sometimes we feel as though we’re helpless and can’t help the people — we are helping in the way that we can by our mapping.”

From that perspective, the data isn’t just a set of pixels; it’s a tool for community recovery. For the first time, local communities were actively requesting drone flights to help document their damage.

“When you have people interacting with you — that human element — you can’t be divorced from what it is that you’re doing to bring a solution to these people. It’s not just data for you. It has more meaning.”

A Blueprint for the Future

As Jamaica moved from immediate response into the long-term recovery phase, the data collected by JFL and its partners is providing a valuable picture for ongoing recovery and future disaster preparations.

After researchers at the University of the West Indies, St. Augustine and WeRobotics analyse the processed geospatial data, it is shared in the cloud with government and academic researchers.

Some of it is also published on OpenAerialMap, a project that provides open-source disaster imagery.

The Jamaican government is using the data to analyse the rebuilding process. The data is also being used to help train AI models to understand building damage and inform complex flood analysis.

Grant emphasizes the less measurable impacts of her teams’ mapping efforts. The response to Hurricane Melissa demonstrated that local expertise, when empowered by technology and global cooperation, can lead to a more effective and equitable disaster response.

A conference in May 2026 in Montego Bay on drones, AI, and GIS — which had been planned for December last year, but had to be rescheduled after Melissa — will now serve as a historic “stock-taking” event, where the lessons learned from the storm might provide a blueprint for the region and the rest of the world.

Building up that kind of local expertise is growing more important, as warmer waters bring larger storms and floods, and as financial resources dwindle amid global policy upheavals, noted Grant.

“The reality is that resources have always been stretched thin, but this year, I think, has seen particular challenges with regards to having resources to do anything.

“But also, I think there has been that recognition — and I’m going to be very blunt — that nobody’s coming to save us, so we have to figure out how to save ourselves. And that’s not a bad thing.”

The response to Melissa was a template for that future, “a local initiative that was globally supported,” she added.

“I’m really proud of that.”
