Street Asset Mapping
Every asset photographed, geotagged and categorised.

Survey data your GIS will actually trust.
Most asset surveys are done by drive-by van, satellite imagery or street-view scrape — methods that miss everything not visible from the road. We walk. Locally-recruited surveyors stand in front of every feature, photograph it, geotag it, categorise it against a controlled list, and feed it through a three-stage quality-assurance process before it lands in your GIS.

Why the method matters
Drive-by misses what isn’t visible from the road.
The standard council asset-survey methods all share the same blind spot. Vehicle-mounted cameras only see what faces the kerb. Satellite imagery misses anything vertical, sheltered or under tree canopy. Street View is years out of date. None of them stand in front of the asset and check.
Walking is slower, but it’s the only method that captures everything — rear-facing signs, kissing gates buried in hedgerows, narrow lanes, pedestrianised streets, public squares and other places no vehicle can reach — with a photograph and GPS position for every record, against a taxonomy of more than 1,200 asset categories.
Drive-by & satellite
What most asset surveys are
Misses a lot
- Sees only road-facing assets
- Misses vertical features and rear-facing signage
- Trees, canopy, awnings block view from above
- No audit trail per asset
- Hard to re-walk for change detection

What we do
Sees everything
- Surveyor stands in front of every feature
- Photo + GPS + structured categories per record
- 1,200+ asset categories in the survey taxonomy
- Three-stage quality-assurance pipeline
- Re-survey by geotag for change detection
What we capture
Point, linear and polygon assets — captured in one workflow.
Three asset geometries, every one geotagged and photographed. The same surveyor records furniture, structures, road markings, parking bays and public places in a single walk — no separate teams, no separate datasets.
01
Point assets
Individual features captured as discrete records: street-lamp columns, road signs, gullies, manholes, trees, bins, bus stops, hydrants, traffic signals, pedestrian crossings, footbridges, gates, kissing gates, stiles, steps, handrails, waymarker posts — each with type, category, GPS and photographs from set angles.
02
Linear assets
Run-along features captured as line geometries: road markings (single and double yellow lines, clearways, bus and cycle lanes), boundaries, kerb runs, surface segments. Each segment carries photographs along the run, and start/end coordinates that match the council’s highway-network base.
03
Polygon assets
Area features captured as enclosed polygons: parking bays, yellow boxes, planters, paved areas, public places. The polygon geometry is recorded on the ground — not estimated from imagery — with photographs and structured attribute data per area.
How it works
Plan the route. Walk every metre. Three-stage QA. Deliver to your GIS.
One workflow whether the network is a city-centre kerbside, a borough-wide street-asset audit, or a 1,000 km rural Public Rights of Way network.
-
Plan the routes
Routes are agreed with the council, then planned and managed manually by our agents and field supervisors. We generate route maps showing planned coverage and update them as the survey progresses. The trail of asset pins itself shows which streets have already been covered. Access, weather window and lone-worker check-in protocol are agreed before each surveyor steps off the kerb.
-
Walk and capture
Locally-recruited agents walk every route on foot. Each feature is photographed, geotagged and categorised using our proprietary smartphone app — with mandatory fields and fixed drop-downs for asset type and category. No free-text variation, no missed fields.
-
Three-stage QA
(1) The app rejects incomplete or out-of-range entries at source. (2) Agents check and can edit data captured before uploading from the field. (3) Each asset is manually checked by our QA team before being approved for use.
-
Deliver to your GIS
Approved data is exported as KML (or shapefile, GeoJSON, CSV) for direct ingestion into your own GIS or asset-management platform. You also view assets and imagery via our map-based web platform.
Re-survey, not re-do
Every asset is geotagged. Every asset can be re-walked.
Because every record carries its exact GPS position and is held under version control, assets can be easily re-verified if they are unchanged, edited if they have changed, or retired if they are no longer there. New assets can be added as they are found. That turns asset surveying from a snapshot into a programme — you see what’s changed, what’s gone, and what’s new.
Proven on the Dublin kerbside programme
The 2025 re-survey, in numbers.
For Dublin City Council we re-walked the entire kerbside asset network in May–June 2025 — the second of two full re-surveys under the EU H2020 SENATOR project. The numbers below are the change-detection result: every original asset re-verified, every removal cleaned out, every new asset added.

Delivered through one of the wettest periods on record. The methodology holds up in conditions where drive-by methods fall back. See the Dublin case study →
What you get
Data in the format your GIS already uses.
Every survey delivers the same set of outputs. Pick the ones your team and stakeholders need; we don’t charge for re-formatting an existing dataset.
Search by address, view every record
Browser access for council users with no software install. Search by postcode, street name or asset type. Click any record to see the photo, GPS position, and category. Multi-user, no training required.
See concentrations — and the gaps
Visualise the distribution of any asset type as a heatmap. Merge maps from different asset types to find areas with a concentration of several, or invert the heat for any type to surface places where it’s missing. For example: streets with public benches but no litter bin nearby.
Where it’s been done
Real engagements. Real councils. Real deliverables.
Two live council case studies — covering city-centre asset auditing at high volume and multi-year kerbside re-survey programmes.

Engagement model
Priced per kilometre or per asset, scoped to the survey.
Every survey is quoted against the scope. Linear networks (kerbside, PROW, highway) are typically priced per kilometre; area surveys (city-centre asset audits, public-places mapping) are typically priced per asset or per square kilometre. Costs include surveying, data processing, QA, reporting and delivery.
01
Highways & Streetscene teams
City-centre and borough-wide street-asset audits. Lighting, signage, drainage, trees, signals, crossings, public realm. Re-survey at 12–24 month intervals to track change. Integrates into your existing asset-management platform.
02
Countryside Access teams
Public Rights of Way (footpaths, bridleways, restricted byways) and asset surveys for upland, lowland and coastal networks. The on-foot methodology adapts naturally from urban kerbside to rural rights-of-way work.
03
Asset-management teams
Kerbside parking and parking-bay surveys, accessibility audits, public-places mapping. Outputs feed directly into compliance, residents’-parking schemes, accessibility-strategy reports and consultation evidence.
04
Smart-city & data programmes
Foundation datasets for connected-asset programmes — the inventory layer that everything else (lighting controls, sensor placements, EV-charging siting) is layered on top of.
