Obstacle Compliance & Airport GIS System
Prototype web GIS for checking structures against aerodrome obstacle limitation surfaces in Kenya.
DjangoGeoDjangoPostGISLeafletICAO Annex 14
Personal prototype, not an official KCAA system. Models ICAO Annex 14 Vol I (8th ed.) surfaces — approach, inner approach, transitional, balked-landing, take-off-climb, inner horizontal, conical, outer horizontal — modelled on KCAA advisory circulars AC-AGA005C (June 2024) and AC-AGA032A (Feb 2026). Certificates are demonstration outputs.
Data sources are public inputs only (OpenStreetMap basemap, public aerodrome lists and published ICAO/KCAA surface definitions). Surface geometry follows the ICAO Annex 14 parameters in code and is a demonstration model, not a certified survey.
