Measure the sky
before you build into it.
Given a coordinate or locality, Skygauge returns the theoretical AAI OLS ceiling, the empirical band of recent NOC approvals nearby, the DP height cap, and the delta between them — the number you actually need before you file.
Theoretical ceiling
Six ICAO Annex 14 obstacle limitation surfaces evaluated across CSMIA, Juhu, and Navi Mumbai — Inner Horizontal, Conical, Outer Horizontal, Approach, Take-off, Transitional. Pure geometry, deterministic.
Empirical reality
11,500+ historical AAI approvals as PostGIS points. Median permissible top by neighborhood, recency-weighted, with the range and % restricted. The number the street actually operates at.
DP height cap
MCGM Development Plan 2034 height layers layered as a second binding constraint alongside aviation OLS. Datum-corrected per-parcel ground from the survey contour. Both shown when they diverge.
Indicative only
Skygauge is an aggregation and analysis layer over publicly-published AAI records, with attribution and deep-links back to the source documents. It is not a formal sanction. Per AAI's own disclaimer, height clearance is issued through the NOCAS portal — this tool is for pre-application planning.
