Slide 1 Annex 15, Amdt. 38, Ch 6. The Pro’s and Cons’ of Thematic Data Sets
Slide 2 FR - easier for providers to implement; UK – less costly on industry to fund; ECTL - Well tailored to the needs of the commercial data publishers; ECTL - Cheaper for AIS/States; ECTL - Might strengthen the business case for SWIM- compliant services (query/reply, notification, etc.); some could be value-added. Single Data Set – Pro’s
Slide 3 FR - Too far reaching (all data needs to be available) - little room for stepped approach; FR - The single dataset may in practice be made of different data sets (eg AIP data + terrain data + eTOD) because of practical aspects (size, format, etc.); FR - How do we deal with existing provisions (eTOD and AMDB) ?; Single Data Set – Con’s 1.
Slide 4 SV - The State has a responsibility to provide information, to make it available in only single datasets will decrease the accessibility compared with the situation today UK - There may be three data sets, AIP, Terrain An Obstacle. UK – Costs of refining single data set lie with 3 rd party providers. Single Data Set – Con’s 2.
Slide 5 ECTL - Other users will need to filter out a lot of unnecessary data; ECTL - Against the current general IT/Internet trends of providing just what is required and not to dump (and overload) all; ECTL - Band-width and file processing problems due to files that can be several hundreds of MB in size; ECTL - Data in datasets will not be provided in a single format (e.g. terrain and topography in geofile and obstacles/AIP in AIXM Single Data Set – Con’s 3.
Slide 6 FR - Continuity with current Annex 15 (at least for eTOD and AMDBs); FR - Easier for the users to get data of immediate interest; FR - In line with a stepped approach: terrain and obstacle data can be a "shall" since it is already one in the current SARPs, other data sets may be "shoulds" first then "upgraded to shalls“; FR -The updates may be more relevant per theme than globally (eg nav data update do not imapct terrain, obstacles, etc.). Thematic Data Set – Pro’s 1.
Slide 7 SV - Digital data distribution is the best way to decrease the costs in the AIS production and thematic datasets are more adopted to individual user needs; UK - More choice for bulk data users in industry; ECTL - Better fits the needs of individual users (e.g. ATC does not need all); ECTL - Easier to deal with the current Standard/Recommended Practice provisions of e.g. ETOD/AMDB ; ECTL - Gives the possibility to AIS to understand who and how is using the digital data. Thematic Data Set – Pro’s 2.
Slide 8 FR - Puts some constraints on providers (multiple data sets to be released every AIRAC cycle); UK - Benefits e.g. costs savings will not be passed on to the end user; UK - More costs on industry; Thematic Data Set – Con’s 1.
Slide 9 ECTL - More work for AIS ECTL - More work for this group also to investigate the needs of the various groups and to identify the data set content ECTL - Might weaken the business case for value added value services, such as on-line query/reply services Thematic Data Set – Con’s 2.
Slide 10 SV - From a flight safety perspective it is important that datasets are available in a format that fits the needs of individual users and without extra charges; UK - Thematic data sets could only be a recommendation and introduced in a phased approach; ECTL - It is suggested to limit the number of thematic datasets and to provide guidance on how to provide filter-query functionality (to avoid 200 different implementations) Other Comments
