Groundline

Platform

One analysis engine, many surfaces

The web workspace, the PDF report, the REST API, the MCP connector and the Copilot all read the same analysis object. That is why the report and the screen can never disagree.

Property Copilot

Ask a question about a specific parcel and get an answer with property facts, governing rules, the calculation, sources, confidence, assumptions, open risks and a next step. Every number is checked against what the engines produced before you see it.

Zoning intelligence

Base districts, overlays in precedence order, use tables with machine-checkable preconditions, and dimensional standards resolved through the full derivation chain. Contextual standards are flagged, not guessed.

Smart site planning

Buildable envelope from real geometry. Exact half-plane offsetting on convex lots, distance-field solution on irregular ones, with easements applied as parallel strips and the method disclosed.

Plan matching

Plan footprints placed and rotated inside the envelope with an exact containment test. Five classifications including "requires variance" and "insufficient data", each with a written reason.

Development scenarios

Full pro forma: land basis, hard, soft, financing, contingency, developer fee, returns, IRR, NPV, DSCR, LTC, LTV, break-evens, sensitivity grids and risk-weighted cases. Every line item shows its formula.

Valuation intelligence

Sales comparison, cost and income approaches reconciled with visible reliability weights, plus residual land value reported separately as the maximum supportable land price.

Discovery

Find vacant, underutilised, oversized, ADU-capable and subdivision-capable parcels by geography, zoning, buildable area, flood status and modelled return. Save searches, receive alerts.

Developer workspace

Projects, teams, roles, documents, due-diligence checklists, activity history, expiring share links and confidential-project mode.
