Validating spatial data Checking digital spatial data by comparing:
Spatial boundaries Descriptive information GISCO Spatial data
Focus on: Occurence of sites (code and name) Position of centroid of sites (lat/lon) Area
Common problems: Centroid position far away or close to another site Area > 5% difference between recorded and calculated value Anomalies between descriptive and spatial database

Problem statement The data flow process is complex and time
consumingResulting in discrepancies of information available at EU
and MS levelResulting in not up-to-date information (N+2 > N-2)
The data flow process is not fully harmonised(although standard data forms, guidelines, … exist)Between spatial and non-spatialBetween SCI and SPA
INSPIRE and SEIS can/should/will help
Streamlining reporting N2K Which data flows are concerned?
Data flow Birds HabitatsProgress Reports (measures and conservation status) Art. 12 (3 year cycle) Art. 17 (6 year cycle)Derogations Art. 9 (1 year cycle) Art. 16 (2 year cycle)Natura 2000 Databases Art. 4 (ad hoc) Art. 4 (ad hoc)Compensatory measures Art. 6.4 (ad hoc) Art. 6.4 (ad hoc)
Streamlining reporting N2K For SEIS it is crucial to have fast updates of high quality
data and time related information series in view of monitoring and reporting obligations
Expert Group on Reporting under Nature Directives DG ENV, EEA, ETC/BD, Member States, other experts
Purpose: Prepare a revision of the dataflow regarding Natura 2000
sites (standard data forms and maps) and switch exclusively to electronic data-flow (also in “legal” terms)
Streamline & modernise data flows Standardisation of required content/data Synchronisation of reporting cycles, merging reports Switch to e-Reporting Ensure links between different data-flows & others
Develop ideas for presentation of the data and their analysis to a wide range of users
Streamlining reporting N2K Topics related to Natura 2000:
1. Identification of problems regarding current data-flow2. Current and future use/purpose of the SDF information3. What type of information is really needed – could some
of the information be deleted? New types of information to be added?
4. Review content of SDF, proposal for revision 5. How can we in future deal with changes more
efficiently?6. Development of technical guidelines for geographic
and descriptive information (link with INSPIRE)
Conclusions and further work
Natura 2000 is one of the environmental policy areas
It is a reporting mechanismWith complex data/information flows
It will be part of SEIS It will build also on INSPIRE
EU INSPIRE GEO-PORTAL (internal) EEA public viewer (external)
First focus is on streamlining the reporting Followed by
New methods to represent information to the policy makers and the public
