APPROACH

A municipal drone programme without the municipal drone programme.

Building your own means aircraft, licensed pilots on payroll, insurance, permits, training and replacement cycles. All of it is a standing cost carried by one budget line, for a machine that flies a few hours a week. Cities that price it out usually order a survey company once a year instead, and live with year-old imagery. On the Aerion network the city buys flights. We place the node, own it, fly it and carry the approvals; departments book missions against a shared schedule, and the cost is split with the industrial and commercial sites in the same radius.

MISSION CATALOG

Sorted by how often it flies, not by which department asked.

This is the part a survey contract cannot copy. Once the aircraft is already overhead, a second pass costs flight time and nothing else, so a city can buy frequency instead of buying a snapshot. Every mission below is a slot on the node, and the cadence is the product.

DAILY

What changes overnight and matters by morning.

D-01 DAILY · 2-4 PASSES

Parking compliance sweep

Two passes over a free-window or paid zone, separated by the length of the window. A vehicle present in both, with the clock run out, is an overstay candidate: two timestamped images, the position, and the elapsed time, handed to the parking officer who decides. Wrong parking is the same sweep: on grass, across a crossing, in a loading bay, a fire lane or a bike lane. Cities that want the data before the enforcement start with the plate-free version below and switch it on later.

D-02 DAILY · WINTER

Winter service verification

Which streets, pavements and yards were actually cleared and gritted this morning, and which were invoiced as if they had been. Snow-pile placement, blocked hydrants and buried bus stops surface on the same pass.

D-03 DAILY · PEAK HOURS

Obstruction & access check

Fire lanes, hydrant approaches, loading bays, bus stops and cycle lanes checked at the hours they are usually blocked. Roadworks are checked against the permit: signed as approved, or a lane taken that nobody applied for.

D-04 DAILY · THAW CYCLE

Roof ice & snow load

During freeze-thaw, icicle build-up over pavements and snow load on flat roofs across municipal buildings, schools and halls. The city closes the pavement or sends the crew before the ice decides for it.

WEEKLY

Things that move week to week, caught as a change.

W-01 WEEKLY · PRIORITY ROADS

New road defects

Priority corridors flown weekly, compared against last week. New potholes, edge failure, blocked gullies and sunken trench reinstatements appear as changes rather than as complaints, and a defect inside a contractor's warranty period is still provable.

W-02 WEEKLY

Construction & permit oversight

Dated aerial record of every active site. Progress against permit, site boundaries, spoil heaps, access closures and mud carried onto the road. It is evidence for the planning department without a site visit.

W-03 WEEKLY · BEFORE / AFTER

Contractor delivery verification

Sweeping, mowing, verge cutting, litter rounds, snow clearing. A pass before the scheduled work and one after it turns "we did it" into a dated image pair. Cities pay for these services largely on trust; this is the mission that most often pays for the subscription.

W-04 WEEKLY · HOTSPOTS

Illegal dumping & container overflow

Repeat passes over known hotspots, verges, forest edges and yards. New piles surface as a change between flights, with coordinates for the cleanup crew, and overflowing containers feed the collection round before residents start calling.

W-05 WEEKLY · ON REPORT

Citizen report verification

Residents already report potholes, dumping and broken benches through the city's app, and each report costs someone a drive out to look. Reports inside the radius are queued onto the next scheduled pass instead: confirmed, sized and photographed before anyone is dispatched, and closed with an image when the work is done.

W-06 WEEKLY · NO PERSONAL DATA

Objects on public land

Café terraces, skips, storage containers, scaffolding, A-boards and market stalls occupy public space under a paid permit with a start and an end date. The pass compares what is standing against what was approved. The object is the subject, so nothing personal is recorded at all.

MONTHLY

The full picture, refreshed often enough to plan from.

M-01 MONTHLY · FULL NETWORK

Road & bridge condition scoring

The whole municipal network, not just the priority corridors. Surface, edges, drainage and bridge decks scored street by street, so the repair programme is ordered by condition instead of by who complained loudest.

M-02 MONTHLY · AFTER DARK

Street lighting outage survey

A night pass over the lighting network. Dark and failing lamps are listed with coordinates, so the round is planned from a map rather than from resident reports weeks later.

M-03 MONTHLY

Public asset inventory

Playgrounds, benches, shelters, signage, courts and paths photographed on a cycle, with damage and wear flagged. The asset register stops being a spreadsheet nobody has walked in three years.

M-04 MONTHLY · BASE MAP

City orthophoto refresh

A current, dated aerial base layer for planning, GIS and public consultation, refreshed monthly rather than whenever the last survey flight was commissioned. Every other mission on this page is measured against it.

M-05 MONTHLY · PLATE-FREE

Traffic & parking occupancy counts

How full each lot and street actually is, hour by hour, and how many vehicles turn which way at a junction. Cities hire people with clipboards for this. Nothing is read off a vehicle, so the same numbers that set parking pricing and junction design carry no personal data at all.

M-06 MONTHLY · OWN ESTATE

Municipal roofs & solar arrays

Schools, halls, offices and depots: the buildings the city itself owns and is slowly covering in panels. Roof damage, blocked drains and dead or underperforming panel strings show up from above long before a leak or a quarterly generation report reveals them.

SEASONAL

Work that only makes sense at one time of year.

S-01 WINTER · COLD SNAP

District heating & building heat loss

Thermal passes over heating routes and municipal buildings while it is genuinely cold. Leaks along the network and the worst-performing roofs are ranked before the renovation budget is set.

S-02 SPRING · SUMMER

Invasive plant & vegetation mapping

Hogweed stands and other invasive growth mapped across verges, ditches and unused land while they are visible, so the eradication round is planned from coordinates and re-checked on the next pass instead of surveyed on foot.

S-03 SEASONAL

Parks, trees & public space

Canopy condition, storm-damaged and leaning trees, path and playground wear across parks and green corridors. Maintenance is planned from imagery rather than from complaints.

S-04 AUTUMN · SPRING

Drainage & flood-risk readiness

Ditches, culverts and gullies checked before the seasons that fill them. Blockages and collapsed sections are found while there is still time to clear them, not during the storm.

S-05 WINTER · PER HAUL

Snow pile volume

Snow removal is billed by the load. Photogrammetry over the dump site and the collection points measures what was actually moved, in cubic metres, on the dates it was moved. It is the same technique the network already runs over stockpiles on industrial sites.

S-06 SEASONAL · THERMAL

Outfalls & illegal discharge

Ditches, storm outfalls and riverbanks checked for what is running out of them. Discharge that is warmer, darker or foaming against the surrounding water is flagged with a location, so the environmental officer samples a specific pipe instead of a catchment.

ON CALL

Flights the city orders on the day it needs them.

E-01 EVENT-DRIVEN · STORM

Storm water & flood extent

Flown while the water is still up. Flood margin, blocked culverts and cut-off streets mapped in one pass instead of reconstructed from phone calls.

E-02 EVENT-DRIVEN · 24-72H

Post-storm damage assessment

District-by-district sweep in the days after a storm or flood. Roof, façade and roadway damage graded into a city-wide priority map for repair crews and insurers.

E-03 EVENT-DRIVEN · ALL EVENT

Public event & crowd support

Overwatch for festivals, markets and city races. Crowd density, entry queues and traffic backup relayed to the organiser and the city's duty officer as it happens.

E-04 FROM 2027 · TARTU FIRST

Public-safety response support

Dispatch-launched flights for rescue, search and incident command, opening with the Tartu U-space work. See public safety.

WHY THE CADENCE IS AFFORDABLE

One flight, several products.

A survey contractor flies for one deliverable and charges for the mobilisation. The same pass over your city produces layers that different departments were each going to buy separately, which is the other half of why frequency stops being expensive.

MAP

CURRENT BASE IMAGERY

A dated orthophoto for planning, GIS, consultation and the public portal. Publishing it is also the cheapest way to build acceptance for everything else the drone does.

3D

MEASURABLE MODEL

Volumes, heights and slopes from the same imagery: stockpiles, snow, spoil, roof areas and shadow studies. Tender documents written from measurements rather than estimates produce fewer change orders.

LOG

THE CITY'S MEMORY

Every pass is kept as a dated record. Fence-line disputes, felled trees, damage claims and "it was already like that" arguments are settled from imagery instead of from memory.

THE OTHER HALF OF THE CITY

A city is also a few hundred buildings that are not the city's.

Most of the roofs inside the radius belong to housing associations, not to the municipality. Each of them faces the same short list: is the roof failing, where is the heat leaving, and what does the renovation application need as evidence. Individually none of them can justify a survey; a single cold, still winter night over the district produces a thermal and visual record for every one of them, and each association buys its own building's report. The municipality gets a district-wide heat map out of the same flight for its energy planning, and the node gets the demand that makes the city's own cadence cheaper.

THE BUDGET CASE

Four of these return money rather than spend it.

Aerial monitoring is usually sold as insight. For a municipality the faster argument is arithmetic: the subscription sits against money the city is already losing.

01

Paid parking that is actually paid

Enforcement today covers the streets an officer can walk. A daily sweep covers the zone. The point is not more fines. It is turnover in paid spaces, loading bays that stay loadable, and fire lanes that stay clear, which is what the fee system was supposed to buy.

02

Services you paid for, delivered

Sweeping, mowing, gritting and snow clearing are invoiced monthly and verified rarely. Before-and-after passes make delivery a matter of record, and one disputed winter month usually costs more than a year of coverage.

03

Works that match their permit

Unpermitted building, unregistered extensions, lanes closed without approval and land used outside its designation all show up as change between two flights. The city checks them against its own registers and acts inside the deadline instead of years later.

04

Defects caught inside warranty

A road failure found four years after resurfacing is the city's problem. Found in the second winter, with dated imagery, it is the contractor's. Cheap repairs also stay cheap: a sealed crack is not a rebuilt junction.

DEPLOYMENT TIER

Two ways a municipality subscribes.

Shared

Network service

For municipalities inside the 10 km radius of an existing node. Departments share the node with the industrial and commercial sites around them, which is what keeps it affordable on a town budget. Scheduled cadence plus callouts. Onboarding 2–4 weeks.

Dedicated

City node

A node placed for the city itself, sized to its districts and its own cadence. Priority on callouts, custom missions, and capacity reserved for municipal work. Deployment 3–5 months.

WHAT WE DETECT

Findings arrive tagged, dated and on a map, not as a folder of photographs.

DETECTION · 01

Pavement & surface defects

Cracking, potholes, rutting and edge failure scored along each street, so the repair list is ordered by condition instead of by who complained.

DETECTION · 02

Water where it should not be

Standing water, flood margin and overflow paths outlined per flight, with the previous flight as the comparison.

DETECTION · 03

Site change against permit

What moved on a construction site between two flights: footprint, height, stored material, boundary encroachment.

DETECTION · 04

Dumping & accumulation

New material appearing where nothing was before, at verges, yards and forest edges, with coordinates and a dated image pair.

DETECTION · 05

Heat loss & thermal anomaly

Warm ground above heating routes and heat escaping municipal roofs, ranked worst-first for the renovation queue.

DETECTION · 06

Vegetation & asset change

Leaning and storm-damaged trees, encroachment on lines and paths, and wear across public space, tracked flight to flight.

DETECTION · 07

Vehicle position & dwell time

Whether a vehicle sits inside its bay, across a crossing, on grass or in a fire lane, and how long it has been there, measured between two passes rather than guessed.

DETECTION · 08

Cleared vs uncleared surface

Snow, grit, litter and cut grass compared against the same frame before the work. The difference is the evidence of delivery.

RESIDENTS

Flights a city can explain at a council meeting.

Municipal aerial work only survives if residents accept it. Every mission on this page is scheduled infrastructure work with a stated purpose, flown on a published cadence, not open-ended surveillance of neighbourhoods. Imagery and detections are stored in Estonian and EU data centres, retained only as long as the mission requires, and released to the department that ordered the flight. We would rather a city publish its flight schedule than defend a secret one.

Enforcement missions carry a harder line, because they touch people rather than assets. The drone gathers evidence; it never issues anything. A parking overstay arrives as two timestamped images and an elapsed time, and a municipal officer decides whether it becomes a notice, exactly as they do on foot today. Registration plates are read only inside the enforcement zones the city has declared, observations that turn out to be compliant are discarded rather than filed, and the whole flow is built to be described in a data protection impact assessment before the first flight rather than defended after it.

WHY AERION

Three reasons cities choose the network.

01

The cost is shared, so the cadence is real

Because a node also serves the terminals, plants and sites around the city, a municipality is not carrying an aircraft on its own. That is the difference between imagery once a year and imagery every month.

02

Built for Nordic conditions

Cold-tolerant to −30 °C and weather-rated for continuous outdoor operation. Winter is when heat loss, ice damage and flooding are worth seeing, so winter is when the network keeps flying.

03

The regulatory work is ours

We hold the operating approvals and do the airspace work, including inside the Tartu U-space sandbox. The city signs a service contract, not an aviation programme.

INSIDE THE CITY BOUNDARY

The municipality is the anchor. The rest of the city rides the same node.

Almost everything the network flies for already sits inside a city: the sites being built, the grid feeding them, the roads between them, the port at the edge of them. When the municipality anchors a node, those operators join at network rates instead of waiting for a node of their own, and the city's own cadence gets cheaper because they did. These are the site types already on the network.

01

MUNICIPAL QUESTIONS

What councils ask first.

Can a small town or rural municipality use the network, or is it only for cities?

Any local government inside the service radius of a node can join, and size is not the qualifier. A rural municipality with a few hundred kilometres of gravel road, a handful of municipal buildings and a seasonal flood problem is often a better fit than a city, because it has the least chance of ever justifying survey flights on its own budget. What matters is whether the territory falls within 10 km of a node, not how many residents it has.

How much of the cost does the municipality actually carry?

A share of it. The node is placed to serve everything inside its radius, so the industrial sites, ports, plants and construction projects around the municipality carry the aircraft, the crew and the approvals alongside it. That is the entire reason a monthly cadence is affordable for a town at all. Exact pricing depends on which missions you want and how often, and a site assessment comes back with a configuration and a quote.

Is drone parking enforcement legal, and who issues the fine?

The drone gathers evidence and never issues anything. An overstay arrives as two timestamped, geo-referenced images and an elapsed time, and a municipal officer decides whether it becomes a notice, exactly as they do on foot today. Registration plates are read only inside enforcement zones the city has declared, observations that turn out to be compliant are discarded rather than stored, and the flow is designed to be written into a data protection impact assessment before the first flight.

What do we tell residents who ask whether they are being watched?

That every flight is scheduled infrastructure work with a stated purpose and a published cadence, not open-ended surveillance. Cities that publish the flight schedule and the mission list have a far easier time than cities that do not. Imagery and detections are stored in Estonian and EU data centres, retained only as long as the mission requires, and released to the department that ordered the flight, with an audit trail per flight.

What does the municipality need in place before the first flight?

A contract, a list of the missions you want and how often, and a named contact per department that will receive the findings. For enforcement missions you also declare the zones. Aerion holds the operating approvals and does the airspace work, so there is no aviation programme for the city to build, and no pilots to hire or licence. Onboarding onto an existing node runs two to four weeks.

When can our municipality start?

Maardu and Paldiski nodes are active in 2026, with Tartu, Pärnu and Narva following in 2027, the Tartu work opening alongside the U-space sandbox. If your territory sits outside a live radius, a dedicated city node is the other route, at three to five months from signature. Tell us the municipality and we will say which node reaches it and when.
