Airport Layout Plan (ALP) Digitization
Turn a paper or CAD ALP into a maintained GIS layer set, so the next update is an edit and not a redraw.
The Airport Layout Plan is the drawing everything else refers back to. Grant applications reference it. FAA reviews development against it. Your own staff use it to answer questions about who leases what. And at a great many small airports it exists as a paper sheet from a decade or more ago, plus a CAD file from an engineer who has since moved on.
What this service is
We convert legacy paper and CAD-based ALPs into a maintained GIS layer set aligned to current FAA airport design standards. Not a one-off redraw — a structured set of layers with real geometry and attributes behind them, so the next revision is an edit rather than starting over.
Why sponsors do this
Under Grant Assurance 29, a federally obligated sponsor undertakes to keep a current ALP and not to permit alterations that conflict with the approved plan. Where a nonconforming change adversely affects federally funded property, the sponsor can be asked to put it right at their own expense.
The practical version is simpler: an out-of-date ALP slows everything down. It delays grant applications, complicates modifications of standards, and turns routine questions into research projects.
What you get
- A georeferenced layer set covering property boundary, runways, taxiways, aprons, buildings and safety areas
- Attribute structure aligned to FAA airport design standards, so the data is usable by other consultants and not just by us
- Source files you own outright — no proprietary lock-in and no licence to keep paying
- A written note of what we could not verify from records, and what a field visit would be needed to confirm
How the work runs
We begin with records, not survey. Half of what small airports believe is missing turns out to exist somewhere — an old survey, a construction as-built, a consultant's file. We establish what is already there before proposing anything that costs money. Where genuine gaps remain, we scope capture to fill only those gaps, using drone or conventional ground survey depending on the accuracy the feature actually needs.
