Airport Proximity Check for Any Plot in India
Distance to the nearest aerodrome, type classification (International / Domestic / IAF / Private), runway map, and air connectivity — for any location in India. Uses OpenStreetMap aerodrome data, 414 facilities mapped.
Why airport proximity matters for any land decision
Airport proximity is a dual-edged signal. The same aerodrome that creates noise and height-restriction concerns for a residential project is a logistics and appreciation driver for a commercial or industrial one.
The concern side: height restrictions and noise
Every aerodrome in India operates within an Obstacle Limitation Surface (OLS) — a 3D zone defined by ICAO Annex 14 and enforced by the Airports Authority of India under the Aircraft Act 1934. Any structure within the OLS that exceeds the notified height limit requires a No-Objection Certificate from AAI before construction can begin. The closer the plot to the runway, the lower the permissible height. Plots under the approach path — even several kilometres away — can face severe restrictions.
Noise is the second concern. The 65 dB(A) contour (AAI threshold for significant community noise impact) typically extends 3–8 km from the runway ends of a busy airport, depending on flight frequency, aircraft type, and wind direction. IAF fighter-aircraft bases generate significantly higher peak noise levels than commercial airports.
The opportunity side: connectivity and land value
Within 20 km of a major airport, land prices for logistics, warehousing, hotels, and commercial uses carry a significant premium in most Indian cities. Airport-adjacent SEZs and industrial corridors (such as Aerocity Delhi, MIHAN Nagpur, and Devanahalli near BIAL) have historically outperformed surrounding real estate by wide margins. For a developer evaluating industrial or commercial land use, airport proximity within 15–20 km is a positive signal.
Even a smaller domestic airport or airstrip matters for freight logistics in Tier-3 markets — air cargo access is a key factor for perishable goods, electronics, and pharmaceutical distribution centres.
IAF and military airfields
India has 136 IAF-operated airfields. Many are co-located with or adjacent to civil airports. IAF bases carry additional restrictions beyond standard AAI OLS maps: security perimeters, low-flying training routes, and classified no-build zones that are not published in public GIS data. This tool identifies IAF facilities and flags them — if your plot is near one, consult both AAI and the Ministry of Defence before any construction planning.
What the result card shows
The analysis returns four signals and a classified map of all aerodromes within range.
How aerodromes are classified
Each aerodrome on the map is colour-coded by type. Classification uses the OSM aerodrome:type field where available, with IATA code and name heuristics as fallback.
- International Airport (violet). OSM
aerodrome:type=international, or IATA code + “international” in name, or IATA-code sibling of a known international terminal. Premium connectivity; strongest logistics and hospitality premium within 15–20 km. - Domestic Airport (blue). Has IATA code; not classified as international. Good domestic connectivity; logistics and commercial premium within 15 km.
- IAF / Military (red). OSM
aerodrome:typeincludes “military”, or name contains “Air Force”, “IAF”, “Military”, “Defence”. Noise concern + classified restrictions; consult both AAI and MoD before construction. - Private Airstrip (grey). OSM
aerodrome:type=private, or name contains “airfield”, “airstrip”, “private”. Noise concern if within 5 km; less noise impact than commercial airports due to lower frequency. - Aerodrome (dark grey). Mapped aerodrome with no IATA code and no specific type tag. Verify status independently — may be inactive or a helipad.
AAI height restriction zones — indicative guidance
The exact height limit at any point depends on the official AAI Obstacle Limitation Surface chart for that specific aerodrome and runway. The guidance below is indicative only — verify at aai.aero or in the AIP before any construction planning.
- Under 2 km. Severely restricted — may be near ground level for plots under the approach path. AAI NOC mandatory; construction effectively blocked within the inner approach surface.
- 2 – 5 km. Typically 45 – 150 m above ground level, depending on surface type. AAI NOC required for structures above the notified limit.
- 5 – 15 km. Up to 300 m in many zones; varies significantly with radial position. NOC required for tall structures (towers, chimneys, cranes); residential construction generally unrestricted.
- Over 15 km. Generally unrestricted unless directly under an air traffic route. No standard height restriction; specific exceptions apply for very tall structures.
Source: Indicative guidance based on ICAO Annex 14 OLS surface definitions as applied by AAI. Not a legal document. Always obtain the official AAI OLS chart for the aerodrome in question.
How the analysis works
One PostGIS query. No external API. Instant result — all aerodrome data is pre-loaded.
You mark the site
Draw the plot boundary, drop a pin, or type an address. We extract the centroid and run a spatial query against all 414 mapped aerodromes within 100 km.
We classify and rank
Each aerodrome is classified by type using the OSM aerodrome:type field, IATA code, and name. IATA propagation ensures that multi-terminal airports (like RGIA with Phase I and Phase II) are correctly classified together. Runways are fetched separately by spatial intersection with the airport polygon — not by radius — so deep-interior runways always appear.
You see a classified map and four signals
All aerodromes within range are shown on the map colour-coded by type. Runway geometries are overlaid where OSM data exists. The result card shows the four signals: nearest any, 15 km list, nearest domestic, nearest international.
Methodology and data sources
All data is pre-loaded in PostGIS. No external API calls at query time — typical response under 100 ms.
Data source: OpenStreetMap
OpenStreetMap contributors (ODbL licence). Snapshot: 2024. Contains 414 aerodrome polygons and points across India, and 548 runway geometries. Major airports (international, domestic trunk routes, IAF bases) are comprehensively mapped. Some smaller general aviation airstrips may have only a point location or may be missing.
Type classification logic
Priority order:
- OSM
aerodrome:typefield (most reliable where set — 7% of records) - IATA code + “international” in name → International Airport
- IATA code alone → Domestic Airport
- Name heuristics: “air force”, “IAF”, “military”, “defence” → IAF / Military
- Name heuristics: “airfield”, “airstrip”, “private” → Private Airstrip
- Default → Aerodrome
IATA propagation: Some airports have multiple OSM entries for the same IATA code (e.g. RGIA with terminal and Phase II polygons, both tagged HYD). If any one entry with a given IATA code is classified as International, all entries sharing that code are upgraded to International.
Runway fetch logic
Runways are fetched by spatial intersection with the airport polygon geometries being shown — not by a distance radius from the query point. This ensures that runways deeper inside a large airport (e.g. RGIA’s secondary runway) are always included, even when the airport polygon edge is at the limit of the map viewport.
Limitations
- No official AAI OLS data: The Airports Authority of India’s Obstacle Limitation Surface maps are published as PDF charts in the AIP, not as open GIS data. The proximity thresholds in this tool are approximations only, not legal regulatory zones.
- No noise contour maps: AAI publishes noise contour data for major airports but not in machine-readable GIS format. Not available in this tool.
- No IAF security perimeter data: IAF base security zones are classified and not publicly available in any GIS dataset. This tool identifies the aerodrome boundary; it cannot show the associated restricted zone.
- OSM completeness: 44 aerodromes in this dataset have only a point location (no boundary polygon) due to incomplete OSM mapping. These are shown as circles on the map.
- Cross-border airports: Aerodromes in Nepal, Bhutan, Bangladesh, and Pakistan may appear within range for plots near India’s borders.
