TerraCity

The physical reality layer for city operations.

TerraCity turns high-resolution imagery, reality meshes, elevation models, city records, and market evidence into a living operational model of the built environment.

From physical observation to fiscal and operational action.

Scroll the city model. Toggle the evidence.

City Reality Layer

A measured baseline of the city.

Start with the physical city: buildings, roofs, roads, sidewalks, trees, public space, terrain, utilities, access, and visible infrastructure.

Imagery Mesh Objects Lineage

Measurement

Objects, attributes, value signals, and change.

TerraCity detects the durable physical layer, enriches it with records and market evidence, and tracks how it changes over time.

buildings, roofs, covered areas, heights, and volumes
roads, sidewalks, curbs, pavement, trees, and canopy
permits, declared area, assessments, listings, and transactions

Fiscal Intelligence

Property assessment from observed reality.

Compare observed physical reality against declared records, assessments, permits, transactions, listings, and neighborhood context to identify review candidates.

Observed Declared Comparable Review

Operations

One reality layer, many city workflows.

Planning, public works, cadastre, assessment, finance, security, defense civil, mobility, utilities, environment, infrastructure, maintenance, and emergency response use the same evidence base.

Measured Inventory

What the first layer should capture.

Not every signal becomes an action. The product earns trust by measuring what can be observed, attaching evidence, and routing uncertainty to review.

Built form

Buildings, floors, roofs, additions, pools, garages, sheds.

Public realm

Sidewalks, curbs, pavement, surface condition, encroachment.

Environment

Trees, canopy, vegetation, water, impervious surfaces, drainage risk.

Fiscal layer

Declared area, taxable base, assessment signals, permit mismatch.

Operations

Access constraints, critical visible infrastructure, maintenance candidates.

Lineage

Source, date, geometry, confidence, review state, and appeal evidence.

Evidence And Confidence

Every action needs evidence.

A city will not act on a black box. TerraCity preserves the source, date, geometry, confidence, and lineage behind every object, measurement, discrepancy, and valuation signal.

Observe

Align imagery, orthos, elevation, point clouds, meshes, records, and market sources.

Measure

Convert the physical surface into city objects, attributes, relationships, and change.

Reconcile

Compare observed evidence with declared records, permits, valuation inputs, and history.

Route

Send high-confidence cases to action and uncertain cases to review with their evidence intact.

Scale

Built for city-scale reality data.

TerraCity is designed for full-city imagery, elevation, mesh, vector, record, market, and sensor inputs. Start with one city, normalize the workflow, and repeat across regions and countries.

TerraCity

Build the operational model of the city.

A measured, current, evidence-backed model of physical reality so teams can understand what exists, what changed, what it means fiscally and operationally, where risk is accumulating, and what action should follow.
