Over 4,300 Koalas Discovered Near Newcastle by Drone: A Conservation Breakthrough

Introduction In an extraordinary discovery, researchers from the University of Newcastle have uncovered more than 4,300 koalas living in bushland on the urban fringes of Newcastle, New South Wales. This landmark finding was made possible using advanced drone and thermal imaging technology, offering new hope for koala conservation efforts across Australia. The study, which surveyed approximately…

Drones are becoming ever more present tools for archaeologists looking to add to their survey and excavation toolkits. They’ve been used to get some great aerial views of archaeological sites and features and sometimes even to discover them!

“Drones are becoming ever more present tools for archaeologists looking to add to their survey and excavation toolkits. They’ve been used to get some great aerial views of archaeological sites and features and sometimes even to discover them! And researchers have now teamed up high-res drone pictures with some nifty machine learning to detect one of an archaeologist’s go to first finds – potsherds.”

Do You Need an Airport NOC Survey in Jaipur? Here's the 2026 Rulebook

The One Approval Most Jaipur Builders Forget About

Municipal building permission, environmental clearance, fire NOC — most developers have these on their checklist. The one that regularly catches people off guard is the Airport NOC, and near Jaipur International Airport, it's not optional paperwork. It's a legal precondition for construction under a national aviation safety rule.

If your site sits anywhere within roughly 20 to 56 km of the airport's reference point, the Airports Authority of India (AAI) has a say in how tall you're allowed to build — and that determination starts with a proper Airport NOC survey Jaipur authorities will accept.

Where This Rule Actually Comes From

This isn't a local Jaipur ordinance. It traces back to Gazette Notification GSR 751(E), issued by the Government of India in September 2015 under the Aircraft Act, 1934. The notification requires height clearance from AAI before construction begins on any structure — building, mast, chimney, transmission tower, even large cranes — within regulated distances of a licensed civil airport.

Jaipur International Airport falls squarely under this framework, which means the clearance isn't a courtesy check. It's enforceable, and violations have led to real demolition orders elsewhere in India after buildings were found to exceed permitted heights post-construction.

How AAI Decides Your Maximum Height

Two distance bands matter here:

Up to 20 km from the Aerodrome Reference Point for VFR (Visual Flight Rules) operations

Up to 56 km for IFR (Instrument Flight Rules) operations

Where a Colour Coded Zoning Map (CCZM) has been published for the city, your maximum permitted height is calculated as:

Permitted Height = CCZM Top Elevation − Your Site's Ground Elevation (AMSL)

Outside a CCZM-covered zone, or above the CCZM cap, the application goes through full technical review via AAI's online portal, NOCAS.

What a Proper Survey Needs to Deliver

AAI is explicit that every height calculation is based purely on the coordinates and elevation you submit — so the survey quality directly determines your approved height. A compliant application needs:

Site coordinates certified to the WGS-84 datum

Site elevation certified to AMSL (Above Mean Sea Level)

A full plot layout capturing every corner (not just a midpoint, unless the plot is under 300 sq. m or it's a mast/chimney)

Building elevation drawings showing proposed top height

Ownership or lease documentation

This data has to come from Survey of India or another authorised, qualified agency — a consumer GPS reading won't be accepted.

The NOCAS Filing Process, Simplified

Survey the site using DGPS or Total Station equipment for accurate WGS-84 coordinates and AMSL elevation

Check zoning status against Jaipur's CCZM, if one exists for your area

Prepare documentation in AAI's required certificate format

Submit through NOCAS, AAI's online application system

Respond to any remarks the Designated Officer raises during review

Receive your NOC — valid 8 years for buildings, 12 years for masts and transmission structures

Most delays happen at step one. Inaccurate coordinates or elevation data doesn't just slow things down — it can mean your entire calculated height limit is wrong, which surfaces as a rejection much later in the process.

Who This Actually Affects

This applies more broadly than most people assume:

Residential and commercial developers planning multi-storey buildings

Telecom operators erecting towers or masts

Industrial projects with chimneys or tall equipment

Individual landowners building within regulated zones

Solar, wind, and transmission line developers

If you're unsure whether your Jaipur plot falls inside a regulated zone, it's worth confirming before finalizing your building design — not after.

Getting the Survey Done Right

Surveying India provides certified Airport NOC survey Jaipur services, covering DGPS/Total Station site surveys, AMSL elevation certification, CCZM zoning checks, and complete NOCAS documentation support — built on prior survey experience in live airport environments where accuracy isn't negotiable.

Quick FAQ

Is this NOC mandatory for every building near Jaipur airport? It depends on distance from the airport reference point and your proposed height relative to zoning limits. Some sites beyond the regulated radius and under 150m may auto-clear, but this should be confirmed through NOCAS, not assumed.

How long does the process take? Field survey work is usually done within days; documentation is typically ready in 2–4 weeks. AAI's own review timeline varies by case.

How long is the NOC valid? n

Rules and zoning maps are periodically updated by AAI — always confirm current limits on the official NOCAS portal before finalizing a design. Last updated July 2026.
