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.

Evidence Model

Compare the city to its records.

TerraCity links physical measurements to administrative records, keeps lineage visible, and routes uncertain cases to review.

Physical evidence: Imagery, mesh, elevation, source date, geometry, confidence.
City record: Parcel, permit, assessment, declared area, use, ownership.
Decision state: Match, discrepancy, uncertainty, review owner, next action.

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

Measure the city as objects, not pixels.

TerraCity turns the physical surface into city objects with geometry, attributes, confidence, lineage, and change history.

Geometry: footprint, roof plane, height, volume, surface, boundary.
Attributes: material, condition, use, coverage, access, visible risk.
Records: parcel, permit, declared area, assessment, listing, sale.

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.

Observation: source stack, capture date, geometry, confidence.
Record: declared area, permit history, assessment, owner notice.
Delta: measured mismatch, comparable evidence, review priority.
Action: approve, field check, notify, update, appeal packet.

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

Measure

Extract city objects, attributes, relationships, condition, and change from the physical layer.

Reconcile

Compare observed reality 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.
