Module @squawk/airspace-data
@squawk/airspace-data
Pre-processed GeoJSON snapshot of US airspace geometry from the 2026-04-16 FAA NASR
cycle. Data only - no query logic, no dependency on
@squawk/airspace.
Part of the @squawk aviation library suite. See all packages on npm.
Coverage
- Class B, C, D, and E controlled airspace (E2 through E7 subtypes)
- Special Use Airspace: MOAs, restricted, prohibited, warning, alert, and national security areas
Usage
import { usBundledAirspace } from '@squawk/airspace-data';
// Inspect metadata
console.log(usBundledAirspace.properties.nasrCycleDate); // "2026-01-22"
console.log(usBundledAirspace.properties.featureCount); // 6842
// Use with @squawk/airspace for zero-config airspace queries
import { createAirspaceResolver } from '@squawk/airspace';
const resolver = createAirspaceResolver({ data: usBundledAirspace });
Consumers who have their own data pipeline can use @squawk/airspace alone and
pass any compatible GeoJSON dataset at initialization.
Data format
The export is a GeoJSON FeatureCollection. Each feature's geometry is a Polygon
representing one airspace boundary. Feature properties include:
| Property | Type | Description |
|---|---|---|
type |
string | Airspace type (CLASS_B, CLASS_C, CLASS_D, CLASS_E2-E7, MOA, RESTRICTED, etc.) |
name |
string | Human-readable name |
identifier |
string | NASR designator or airport identifier |
floor |
AltitudeBound | Lower vertical bound |
ceiling |
AltitudeBound | Upper vertical bound |
state |
string or null | Two-letter US state abbreviation |
controllingFacility |
string or null | Controlling ARTCC or facility |
scheduleDescription |
string or null | Operating schedule text |
AltitudeBound is { valueFt: number, reference: 'MSL' | 'AGL' | 'SFC' }.
Data source
All geometry and metadata is derived from the FAA National Airspace System Resource (NASR) 28-day subscription, which is public domain. Class B/C/D/E boundaries come from the NASR ESRI Shapefile and SUA boundaries from the AIXM 5.0 XML files. The build pipeline that produces this dataset lives in tools/build-airspace-data.
