CDDA data collection 2012

Released on 2011-12-16 by: Marek Staron

To: Eionet PCPs and NRCs for Nature Protection and Biodiversity

Cc: Eionet National Focal Points

From: Marek Staron, EEA, on behalf of Rania Spyropoulou

Dear Colleague,

Deadline for the CDDA deliveries is 15 March 2012.

We are writing to inform you of the detailed plans for the CDDA annual data collection that is, as you know, one of the agreed EIONET Priority Data Flows. We hope that this letter will be useful as you organise a programme of work with your network in order to validate the existing data published by EEA and to provide any new information available by the deadline for deliveries 15 March 2012.

Update of the CDDA data

Do not use a different or older version of the template database.

The technical specification for the CDDA has been changed only in few minor details. Definitions are available in the Reportnet Data Dictionary.

The pre-loaded template database provided by EEA should be verified and updated with your new information. Do not use a different or older version because quality checking and aggregation routines will fail.

CDDA template database

You will find the pre-loaded template in a draft envelope (with number 2012 in its name, but otherwise following the naming convention you have used in the previous envelopes) for each country in the national folder under EEA requests in Reportnet Central Data Repository (CDR). Nominated data reporters and national focal points have access to this envelope.

The pre-loaded template database provides a possibility to run selected quality checks on the data. We recommend you use it and fix the detected issues before you export the data to XML and upload them on the agreed data repository (see below).

It is important that you contact ETC BD to receive site codes for new sites or for sites that have not previously been reported to CDDA. This is the value that must be used for SITE_CODE field. It is the key that allows us to join tabular and spatial information for each site.

Key issues

It is vital that the key field SITE_CODE is correctly defined and complete in the spatial data provided for sites.

You are asked once again to concentrate resources on improving the quality of digital boundary information for your sites. It is vital that the key field SITE_CODE is correctly defined and complete in the spatial data provided for sites. You should provide information as requested on the size, the coordinates (latitude and longitude) and the IUCN category.

EEA will calculate the coordinates of sites for which correct site boundaries have been delivered. Countries should indicate in the appropriate database field if they want this to be done. These coordinates will satisfy the coordinate requirements criteria for the Eionet progress report. The calculated coordinates will be made available in the sites table of the next version of the European data set.

You are also asked to pay attention to points raised in the feedback reports on your previous deliveries which you find together with the preloaded template database in the package uploaded to the CDR. EEA does not correct any errors or problems identified during quality control. Please make use of the quality checking services. Do not hesitate to ask if you have questions.

Data Delivery and Automatic QA

We kindly ask you to do not upload your datasets before February.

Your quality controlled data should be uploaded, after consultation with the National Focal Point, either to the Central Data Repository or to your national EIONET server, depending on the choice of your country for delivering EIONET priority data by the deadline of: 15 March 2012.

You can upload back to the draft envelope created by EEA or if this has been completed you can create a new envelope.

The delivery should consist of the following parts:

  • Microsfot Access database - updated template database. Please use only the original .mdb format, don't change it to the newer .accdb
  • XML files - these files should be created by you by using 'Generate XML files' function in the database template. XML files are needed for Automatic QA service to provide you with an immediate feedback on the quality of your delivery.
  • GIS boundaries data - updated .shp files with sites boundaries polygons. Boundaries of designations not creating sites should be also present if possible.
  • Additional information - any supporting or clarifying information that you think is necessary in order to explain your delivery. Use any format you think will serve the purpose.
Automatic QA procedures, which give the immediate feedback after you upload the data on the CDR, will be updated by the end of January only. Therefore, we kindly ask you to do not upload your datasets before February. We will send to you another letter, with more detailed instructions, when the system is ready for your deliveries.

Post delivery

Countries may be invited to redeliver a corrected version by end of April.

ETC BD will merge the data from all countries to create the new version of the European CDDA dataset. Countries may be invited to redeliver a corrected version by end of April if there are outstanding errors or omissions. It is planned to publish the new version in EEA Data Service during September 2012. This version will again be accompanied by a quality report.

The data delivered in 2012 will be used by EEA for on going biodiversity assessments. It will be available for interactive queries through EUNIS - the European Nature Information System, and will be supplied, as usual, to WDPA - the World Database on Protected Areas where sites for public dissemination will be made available in Protectedplanet.

Evaluation and scoring criteria


EEA has reported to EEA Management Board on country responses to the CDDA National data collection since 1999 (see archive of EIONET Progress reports). The purpose of the priority data flows report is to show progress against agreed, stable, well-defined objectives in order to allow countries to focus their resources on putting regular reporting procedures in place.

The evaluation criteria for the 2012 data collection are unchanged. We hope that the support for coordinate calculation and quality checking provided by EEA this year will continue to help all countries towards high scores.

CDDA preparation for INSPIRE

The Eionet Biodiversity workshop will take place towards the end of Q1 2012. Invitations will be sent in due course. We would like to give you an early warning that the agenda will include CDDA preparations for INSPIRE as the INSPIRE Directive comes into force in 2012 (for Annex I themes including Protected Areas).

Helpdesk and support


If the people working directly on the CDDA data delivery in your country are not PCPs or NRCs, please copy this letter to them so that they are aware of the wider context of their work at the European level.

I would like to take this opportunity to thank you for your continued support and look forward to another successful annual data flow.
