Presentation: Quality evaluation process in eTOD (electronic terrain and obstacle data) Database

Panelist: Jaroslav Zemek – RIGTC Zdiby, CZ

The presentation will inform about the achievements of RIGTC Zdiby - CZ, in the solution of the project "The Assurance and Assessment of Aerial Obstacles Quality". This project was solved for the Czech Ministry of Transportation in 2009 and 2010. It represents the first practical application of the ISO 19100 Series for Geographic information in aviation branch. The primary aim of this Project was to develop the technology for specification, ensuring, assessment and publishing the quality of the aerial obstacle data in accordance with Commission Regulation (EC) Nr. 73/2010, ICAO Annex 15, national legislation and with all key standards and norms of ISO 19100 Series - Geographic information related to quality and metadata.

Project „Database of Aerial Obstacles“ Contract with the Czech Ministry of Transportation (MT)

Joint team led by RIGTC consisting of specialists from MT, Aeronautical Information

Services (AIS), Ministry of Defence (Geo, AF), surveyor of company operating the Prague – Ruzyně Airport

Solution in 2009 - 2010, eTOD – only „aerial obstacles“ (AO) WPs:

- development of proven data gathering technologies compliant with Q and I requirements

- generation, administration and update of database - development of proven technology of Q and I assessment - development of technology of positional accuracy assessment of

aeronautical charts

Research and development, design, testing, validation of methodology and technologies meeting the quality and integrity requirements

Documentation and results are stored in „e-Projekty“ at MT CZ (CG942-064-910) and in RIGTC library

Database of Aerial Obstacles - eTOD

Web application (technologies ASP.NET and C#, NET framework 2.0, XML)

Browsers IE 7.0 and FireFox 3.6 or higher versions (Chrome, Opera ) User dialogue in Czech language (English is being prepared) Database MySQL Focus on security, integrity, controled access and strict historization All important changes are logged (what, when, whom, why - history of

changes) Time Slices Deleting of data may be prohibited (optional) Coding catalogues, data item description and gazetteer are in CZ and

ENG Data is described by metadata (about data set, about feature) Metadata contains results of Quality, Integrity and Consistency checks

(CRC 32Q) and are updated dynamically Information on obstacles is accesible on web via user friendly forms


Database of Aerial Obstacles - eTOD

Basic functionalities: Setting up (options, parametres for quality checks, etc.) Import and export (digital forms on web, off-line in exchange format XML) Viewing, filtering, searching, sorting and editing of obstacle data Quality checks (loggs, protocols, history) Digital photos viewing

Actions available (icons): depending on authorization (admin, editor, user)

Full info incl. digital photos Editing - application, logical and database checks are carried out before acceptance of each

change - historization and logging of all changes

Back-up (by standard MySQL tools or by tools of Application layer) Time Slices and comprehensive History


eTOD - Quality and Integrity Requirements



Numerical requirements for Obstacle data



Numerical requirements - ICAO Annex 15 (Accuracy, Resolution, Integrity level, Confidence level, Periodicity……..)

Ability to determine the data origin (institution – persons, methods, procedures)

Credibility of originators and data providers Level of assurance of data availability before its effective start

date/time till effective end date/time

Documentation (description of requiremets, methods, procedures, assessment, personal – traceability)

Declaration of data usability for particular application



Argumentation and evidence to show, that:

Accuracy and resolution requirements are met at data origination Origin and change history for each data item is available for audits Data is complete or missing items are declared All processes (data origination, production, storage, handling, processing,

transfer or distribution) for each data item are defined and are adequate for assigned integrity level

All personnel is proffessionally skilled Maintenance of each obstacle data is secured throughout its lifetime System of error reporting and efficient feedback from users are established ……


Responsibilities of participating bodies

Implementation of Quality Management System within participating organizations (ISO 9001:2008)

Adequate proffessional skills and moral quality of personnal (courses and training for ISO 19100 Series, methodology, security clearance ….)

Participation at elaboration of DPS according to ISO 19131

Strict application of binding documentation (EU, Eurocontrol, ICAO, CZ_legislation, aviation regulations L15 etc.)

Secured data transfer (application of CRC 32Q method ), database integrity and database access only for authorized subjects

Close cooperation of all subjects (originators, database administration, data providers, data users …), regular feedback…


Spatial Data Quality Philosophy

Data Product Specification Spatial Data Quality Elements/Sub-elements

Accuracy (Positional, Thematic, Temporal) Resolution of data Integrity Traceability Completeness (Commission, Ommission) Logical consistency (Format, Conceptual, Domain, Topological consistency)

Data Quality Evaluation Procedure Data Quality Reporting/Metadata


Data quality philosophy consists of the following four topics:


Data Product Specification



Data Quality Evaluation Procedure



Data Quality Reporting/Metadata


Quality plans


Software for eTOD Quality Assessment


Basic principles for calculations and Quality assessment Quality scope Quality measures Quality assessment procedures Quality results Type of quality results values

Quantitative Quality assessment and presentation of results Reports from Quality checks Records in Metadata of database and Metadata of feature

Non-quantitative Quality assessment and presentation of aggregate results

Historization of the Quality assessment

Periods for Quality assessment

Information on Aerial Obstacles


Dynamic filtering


Time Slice


Quality checks


Detailed Report from Quality check


History of Quality checks


Metadata about Database of Aerial Obstacle


Conclusions – future development


Technology: is proven by the users and is compatible with recent system of AIS of the Czech

Republic is ready for application without significant financial bardens will consolidate several AO databases being operated recently in CZ into unified, central

and standardized one will satisfy user needs for next about 5 years creates the solid base for further development (DIGEST and FACC, AIXM v. 5.1, UUID

etc.)

Proposals for future development: Streamlining of technologies, field survey of data with higher level of integrity (10-5),

wireless field data transfer , optimization of processes, additional functionalities for Quality checks etc.

Integration of eTOD with other state information systems and GIS, databases and registers

Full exchangability with European Aeronautical Database (EAD) Application of new digital geospatial data, especially from laser scanning of CZ

territory English language localization
