City-Centre Asset Survey — 2022

Inakalum surveyed every asset and public place across Newcastle’s 3.1 km² city centre on foot — over 30,000 datapoints in ten weeks. Ten locally-recruited agents (selected from 50+ applicants), one survey manual, the Inakalum smartphone capture app, and AI analysis of every high-resolution photograph captured to add metadata. Delivered as KML for ingestion directly into NCC’s own GIS.

A heritage cast-iron lamp column with twin lanterns is prominent in the right foreground; the curve of the historic stone-built terrace runs into the distance; pedestrians cross the wide pavement; a Waterstones storefront and parking signage are visible on the left.

The headline

Over 28,000 assets and 2,000 public places, in ten weeks.

Newcastle demonstrated the walking model at high volume. Ten agents, a tightly-organised survey programme, and an asset taxonomy that covered everything from individual street-lamp columns to parking facilities. The result: a city-centre dataset richer and more current than NCC’s existing records.

1,063

Street-lamp columns

Every lamp column geotagged, photographed and categorised. AI image analysis was used to identify which columns carried additional apparatus — CCTV, signage, banners, communications equipment.

1,625

Gullies

Drainage gullies captured across the city centre — the dense, easy-to-miss assets that matter for highway flood management and maintenance scheduling.

433

Road signs

Every traffic and information sign, recorded with category and photographs. Critical for compliance and renewal planning.

2,000+

Public places

Distinct public places — squares, paved areas, planters, gathering spaces — recorded as polygons. The dataset behind public-realm and accessibility programmes.

Plus 359 manholes, 411 trees and 492 parking facilities — among the 28,000+ assets in the full inventory.

AI analysis on every image

Metadata that scales beyond what a surveyor can record in the field.

The on-foot capture method produced high-resolution photographs of every asset. Inakalum’s AI pipeline then went back through those photographs to add metadata that would have been too time-consuming to record manually.

“The walking survey gave us the raw imagery. The AI pipeline then went through it and identified, in seconds, which lamp columns carried additional apparatus and which didn’t. That’s a classification you can’t reasonably ask a surveyor to do live in the field, but it’s exactly what an asset-management team needs to plan a programme.” — Inakalum project record, October 2022

What Newcastle received

Standard KML, ready for NCC’s own GIS.

The full asset and public-places dataset was delivered as a KML export — the standard geospatial interchange format every modern GIS platform supports — for ingestion into NCC’s own systems. No custom integration, no proprietary lock-in.

01

Per-asset records

Every record carried type, GPS position, mandatory photographs and (where AI-analysed) additional category tags. Searchable by NCC officers via the council’s own platform.

02

Multi-type structured dataset

Point assets, linear assets and polygon assets all delivered in the same KML structure — 28,000+ assets and 2,000+ public places, distinguishable by type and category in the final dataset.

03

Foundation for follow-on work

The Newcastle dataset established the city-centre baseline that subsequent council programmes could refer back to — the kind of one-time foundation survey that supports asset-management, accessibility and smart-city activity for years.
