Aviation TOD

Obstacle and terrain data meeting the data quality requirements for in-flight and ground-based applications provide significant safety benefits for international civil aviation. The International Civil Aviation Organization (ICAO) requires all ICAO-participating States to ensure the availability of digital terrain and obstacle data for four areas covering the territory of the State as well as well as the operationally significant areas around an airport.

The terrain and obstacle data collected must comply with the regulatory requirements defined for each area. The obstacle and terrain data is stored digitally and made available as digital data sets for operational use by airspace users and air navigation service providers The four basic coverage areas are below:

Area 1

The entire territory of the State

Area 2

Constituted by 2d, a 45-km radius section around the airport (terminal control area), and by three other sections: 2a, 2b, and 2c.

Area 3

Aerodrome or heliport area extending from the runway center line to 90 m and from other parts of the aerodrome movement area to 50 m.

Area 4

The radio altimeter operating area runway, category II or III; the width of Area 4 is 60 m on either side of the extended runway center line, while the length is 900 m from the runway threshold.

VeriDaaS’ TOD service provides airports, airlines, and air-traffic authorities with cost-effective digital data to help facilitate ICAO compliance, as well as for other applications in the aviation domain. Our datasets can help relevant authorities in the State meet the data quality requirements specified by ICAO as well as the national requirements defined by the State (i.e., one collection can satisfy multiple uses). Our data service is designed for cost-effective collection and provision of required data and contributes to decreased costs for aviation by providing the tools needed to identify possibilities to reduce fuel waste, cut carbon emissions, augment cargo loads and support the implementation of Unmanned Aircraft Systems Traffic Management(UTM).


International Expertise

Data compliant with ICAO requirements and industry standards as prescribed by ISO, RTCA (DO) and EUROCAE (ED). We can help simplify your ICAO Annex 15 TOD compliance by remaining current and up to date on all current standards and future amendments.

Multi-Disciplinary Skillset

Our highly skilled teams include aviation and geospatial experts with extensive experience across aeronautical and terrestrial surveying, data processing and software development. Our teams operate within discrete workflows according to primary areas of expertise, guided by well-defined and documented rules, standards, and processes.

An Innovative and Economical Solution

VeriDaaS uses the most technically innovative geospatial technology available to deliver the highest-quality TOD solution possible. The efficiency of our Geiger-mode aerial LiDAR helps to make ICAO compliance more cost effective than conventional terrestrial surveys, and we provide easy access to seamless data of homogenous terrain and obstacle data that is centrally located.

Access to Proprietary Geiger-mode LiDAR

Our proprietary high-density Geiger-mode LiDAR systems, developed by L3-Harris, collect high-resolution data of up to 50 pts per m2 providing a singular homogenous data source across all areas. The superior accuracy of Geiger-mode data (less than 10 cm vertical accuracy) enables optimization of flight plans and improved utilization of airspace.

Geiger-mode LiDAR collection is three to four times faster than traditional methods. This enables data to be collected in a shorter timeframe, reducing both overall cost and disruption to airspace. In addition, data can be collected from a higher altitude and at night, further reducing airspace disruption.

Geiger-mode LiDAR detects smaller features, such as antennas, which are often missed by other technologies. Our high-resolution datasets also meet the needs of many other use cases, providing additional economic value beyond TOD requirements. For example, our datasets can support the development of emerging aviation activities such as local unmanned commercial drone deliveries and urban air taxis.

Data as a Service

VeriDaaS and its partners provide multiple avenues of access to LiDAR Point clouds and TOD-specific data layers. Moreover, our sophisticated change-detection algorithms utilize satellite imagery to identify terrain and obstacle changes, triggering alerts when data updates are required.
