E-TOD (Electronic Terrain and Obstacles Database Suite)

An integrated system to acquire, validate and collect all aerodrome survey data according to ICAO Annex 15 (AMD 33 and 34).


IDS E-TOD is the software solution designed to manage terrain and obstacles data ensuring compliance with the international quality requirements. Its main functionalities consist in data administration, reporting and processing, making all elements available for airport areas modelling and ICAO Obstacles Charts Construction and Delivery.

A proper database structure (TOD, Terrain and Obstacle DB), supporting all activities, represents a common layer either to perform charting or to design airspace and flight procedures in the FPDAM interactive environment.

IDS E-TOD is composed by three main blocks:

  • Survey Catalogue: containing all files;
  • Aerodrome Survey DB: containing aerodrome and terrain survey data;
  • Obstacle DB.

Data Storage and Management

A range of tools are available to administrate all terrain and obstacles data, according to survey data types and activities to perform.


Survey Data Manager and Survey Catalog

Terrain models (DTM, DSM), orthophotos, raster files, 3-D vectorial maps and raw surveyed data lists are imported into the archive. The Survey Data Manager allows organisation of all documents in "Families", where each family represents document types and associated classification data, or metadata.

E-TOD has version-ing capabilities where modifications of documents are tracked and new versions are automatically produced, which can be compared to previous versions in the Document History.


CRC

The CRC (Cyclic Redundancy Check) code is automatically computed to protect all documents of a family and to ensure data integrity.


Stand-Alone Validation Procedures

All data to be put into the Survey Catalogue undergo several validation checks before final storage. If the data doesn't satisfy quality requirements they are not imported and another data refining process is required.


Aerodrome Survey DB and Obstacle DB

Loading all checked data into the Aerodrome Survey DB and the Obstacle DB grants survey and obstacles data maintenance according to Annex 15 (AMD 33 and 34). Complex metadata list with a high degree of flexibility and configuring can be managed. The use of default values ensures total compliancy with ICAO requirements.


Data Reporting

The Survey Data Manager produces reports containing the entire list of operations carried out in the catalogue, in the Aerodrome Survey DB and in the Obstacle DB.


Data Processing

The Survey Data Analyser allows the users to review the input data and to use the ICAO Annex 4 and 14 surfaces construction for obstacles interference evaluations, which gives feedback to the Terrain and Obstacle database.


Ambiguous Survey Data Solving

A procedure, executed during the data loading phase, informs the user when surveyed data have similarities with other surveys already present in the DB. The system allows the user to choose the appropriate action: update, ignore or insert the ambiguous element. To support the user in solving the ambiguities the Survey Data Manager provides functionalities to visualise the suspicious elements in the graphic environment.
