Proposal for reporting of air quality
management zone boundaries
Version 2.0
1
Current situation
• 2004/461/EC laying down a
questionnaire to be used for annual
reporting on ambient air quality
assessment under Council Directives
96/62/EC and 1999/30/EC and under
Directives 2000/69/EC and 2002/3/EC
of the European Parliament and of the
Council
• Form 2 Delimitation of zones and
agglomerations

(1) The Member State should give not only
the zone name, but also a unique zone code.
(2) The Member State should indicate the
pollutant(s) to which the zone applies using
the codes: ‘S’ for SO2, ‘N’ for NO2/NOx, ‘P’
for PM10, ‘L’ for lead, ‘B’ for benzene, ‘C’ for
carbon monoxide and ‘O’ for ozone,
separated by a semicolon,
or ‘A’ if the zone applies to all these
pollutants.
Notes to Form 2:
•
•
•
5
If zones have been separately defined for health,
ecosystem and vegetation protection, the Member
State should use the following codes: ‘SH’ for SO2
health protection, ‘SE’ for SO2 ecosystem protection,
‘NH’ for NO2 health protection, ‘NV’ for NOx vegetation
protection.
(3) It should be indicated whether the zone is an
agglomeration (code: ‘ag’) or not (code:‘nonag’).
(4) Optionally, the Member States may add the area
and population size of the zone for further processing
of the data at European level.
Notes to Form 2:
•
•
•

(5) For further processing, the Member State
is requested to fill in the zone borders in a
standard format (polygons, using the
geographical coordinates according to ISO
6709: geographical longitude and latitude).
The Member State is requested to provide
separately a map of the zones (as an
electronic file or on paper) to facilitate the
correct interpretation of the zone data.
The Member State must provide at least
either the zone borders in Form 2 or a map.
Guideline referring to Commission
Decision 2001/839/EC (January 28th
2002) provides additional guidance on:
•
7
Allocation of zone names and codes
National naming methods for zones may
differ strongly between Member States.
Because of this, an additional zone code is
needed to unambiguously identify zones. The
zone code is defined as CCxxxx, where CC is
the abbreviation of the Member State’s name
as given in Table A of this guideline and xxxx
a serial number to be given to each zone by
the Member State. The Member State is
entirely free in allocating serial numbers to
the zones.
And on:
• Information on zone borders It is
mandatory to provide information on
the zone borders. There are several
ways in which these borders can be
provided:
• Maps printed on paper
• Bitmaps
• Zone borders coordinates in electronic
form
8
Zone borders coordinates in electronic
form
•
•
•
9
The most exact and flexible form of reporting
how the zone territories have been defined is
inthe form of coordinates of zone borders
In view of the anticipated use, a very high
resolution of the zone borders is not needed.
A good balance between file size and spatial
detail is a resolution of about 1 km.
For correct interpretation the Member State
is requested in Note 5 to add a map of the
zones; this is essential if the zone borders
consist of more than one closed curves (e.g.
two combined separate areas or a “hole” in
the zone).

Processing at the European level:
overview presented at 10th EIONET WS
•
For presentation of air quality information by Commission
and EEA, an EU-wide zone map is needed.
•
Half of the EU15 Member States have sent digital zone
border coordinates:
•
•
as border polygones or
as GIS files.
But hard to rework to a consistent EU map!
•
13
Consistency of zone borders between Member States is
important; proposal for exchange to be developed soon.
Proposal for exchange for:
• Zone borders based on administrative
units
• Zone borders with a different basis
14
Case 1: Zone borders based on
national administrative units
Proposed steps:
1.
For each AQ zone, the data supplier provides the
national administrative units code(s) which the zone
covers.
2.
EEA/ETC adds the zone code as an attribute to the
European data set of administrative boundaries. The
geographical boundaries of national administrative
units are maintained by MS national mapping
organisations.(EuroBoundaryMap formerly known as
SABE)
3.
The zones and the characteristics reported in the AQ
questionnaire can be displayed as maps at European
level.
An illustrated example for Case 1 follows..
15
Case 1: Zone borders based on national
administrative units. Example 1/3
•
Czech Republic 2003
questionnaire
•
•
16
Zone code: CZ062 Full
zone name:
Jihomoravský
Corresponds to national
administrative unit:
Jihomoravsky kraj with
the boundary shown
here.
Case 1: Zone borders based on national
administrative units. Example 2/3
•
17
Austria 2003 questionnaire
•
Zone code AT_03 Full
zone name:
Niederösterreich
•
Zone code AT_09
(agglomeration) Full
zone name:Wien
•
Correspond to national
administrative units:
Niederösterreich AT12
and Wien AT13 with the
boundaries shown here.
Case 1: Zone borders based on national
administrative units. Example 3/3
•
•
18
Zones CZ062 and
AT_03 share a
common
international border.
No time consuming
“geometrical fitting”
between countries is
required during the
processing of the air
quality zones.
Case 1: A zone border can be based on
several national administrative units
Austria 2003 questionnaire
AT_O3_1 Nordostösterreich ohne AG Wien
AT_O3_2 Südostösterreich ohne AG Graz
AT_O3_3 Oberösterreich und nördliches
Salzburg ohne AG Linz
AT_O3_4 "Pinzgau, Pongau und Steiermark
nördlich des Alpenhauptkamms"
AT_O3_5 Nordtirol
AT_O3_6 Vorarlberg
AT_O3_7 Kärnten und Osttirol
AT_O3_8 Lungau und oberes Murtal
Example: AT_O3_7 = Kärnten AT21+ Osttirol AT333
19
Case 1: How would data suppliers provide the
information on national administrative units?
•
EEA/ETC would prepare a standard template containing the
hierarchical list of all national administrative units for their
country.
•
The data supplier would indicate on the template the
administrative unit(s) on which the zone is based.
•
The data supplier would choose whether to use just the smallest
administrative units or to use highest appropriate level in the
hierarchy
•
A separate template would be completed for each zone identified
in the air quality questionnaire.
•
All MS regularly supply information on administrative units to
Eurostat under REGULATION (EC) No 1059/2003
http://europa.eu.int/eurlex/pri/en/oj/dat/2003/l_154/l_15420030621en00010041.pdf
•
The template provided to data suppliers would be based on the
lists of national administrative units and their codes regularly
published by Eurostat at:
http://europa.eu.int/comm/eurostat/ramon/nuts/home_regions_en.html

/04_sabe.asp
Case 2: Zone borders not based on
national administrative units
Proposed steps:
1.
EEA/ETC prepares a geographical template for each MS. The
template is derived from the EuroBoundaryMap data set and
consists of
•
The national boundary
•
Spatial reference data
•
Pre-filled meta information
2.
For each AQ zone, the data supplier imports the geographical
coordinates for the zone boundaries into the template. The zone
code must also be provided in order to link the geographical
information with the AQ questionnaire information
3.
EEA/ETC aggregates the geographical templates into the European
data set
4.
The zones and their characteristics can be displayed as a map at
European level.
An illustrated example for Case 2 follows..
23
Case 2: Zone borders not based on national
administrative units. Example 1/3
•
24
The data supplier can use the provided GIS
template with default spatial reference
information or convert to another documented
reference system.
Case2: Zone borders not based on national
administrative units. Example 2/3
•
•
25
The data supplier can
import prepared
geographical coordinates
for the zone boundaries
into the geographical
template.
Existing GIS files (e.g.
shape files) of the zone
boundaries can also be
imported into the
geographical template.
Case 2: Zone borders not based on
national administrative units. Example 3/3
•
26
Quality of the
reported zone
boundaries with
respect to the
national boundary
can be checked in
GIS software before
delivery by the data
supplier.
Case 2: Why should the data supplier use
the geographical template?
•
•
•
•
27
The geographical template allows the data supplier to
see how the national zones appear in the European
context. The data supplier is best placed to recognise
good quality and resolve any problems.
In case of difficulties, it is more efficient to provide
support to the data supplier during the reporting
process rather than to return back weeks or months
later to find out “what happened”.
Many of the zone boundary coordinates provided
under the current procedure cannot be used because
they lack spatial reference information needed for
aggregation.
Zones made up of more than one polygon (e.g.
offshore islands) are very hard to process under the
current procedure.
Delivery of the zone boundary information
– proposal for pilot in 2006
•
•
•
•
28
MS would delivery the boundary information
for all their zones during Q4 2006.
Delivery point would be same as for AQ
questionnaire in CDR
Delivery would comprise either the
completed administrative units templates
and/or the completed GIS template(s)
A draft European map showing the zone
boundaries would become available in spring
2007
