From: Mette Lund and Marek Staron, EEA
Deadline for the CDDA deliveries is 15 March 2015
We are writing to inform you of the detailed plans for the CDDA annual data collection that is, as you will 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 2015.
Data packages with pre-loaded template files are uploaded in draft envelopes on the CDR
As in previous years, also for this data collection the EEA has prepared a data package with pre-loaded template files and additional documents has been prepared for each country. The package contains:
*** is for country code or name
Each of the country data packages is uploaded in a draft envelope on the Reportnet Central Data Repository (CDR), in the respective CDDA collection folder of the country. The envelope has 2015 in its name, but otherwise follows the naming convention that you have used in the previous envelopes. Nominated data reporters and national focal points have access to this envelope.
Do not use a different or older version of the template database
The pre-loaded template database contains the latest national data provided by you in a structure defined by the CDDA Data Dictionary. It should be verified and updated with your new information. The analysis reports, included in the package, provide information on problems and errors we have detected in your previous deliveries. Please try to correct them or provide an explanation if it is not possible.
Do not use a different or older version of the database template because quality checking and aggregation routines will fail. The database template 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).
Use site code allocation web service to reserve new codes for your sites
SITE_CODE is the unique identifier throughout the CDDA dataset. The web service for allocation of site codes for new sites is available at:
It is vital that all spatial features are given correct SITE_CODEs
This year a new spatial specification was set up in order to improve further the quality of the reported spatial polygons and points. The current country deliveries are highly diverse when it comes to number of files, formats, names and projections. A document with the new spatial specifications is part of the data package and is also available for download at CDDA Data Dictionary page.
It is vital that all spatial features (site polygons) are given correct SITE_CODEs, which allows them to be properly linked with the site records in the tabular database. The SITE_CODE is also used as unique identifier by the World Database on Protected Areas (WDPA).
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.
Ensure that your marine sites are reported
Given the rising focus on the protection of the marine environment, on global as well as European level, it is important to have data (in particular the site boundaries) to show what countries have already put in place. There is no requirement to redeliver marine sites already provided under international agreements, e.g. the Regional Sea Conventions, or the Natura 2000 and Emerald networks. Relevant guidance notes, incl contact information on the national participants to the MSFD Marine Expert Group, are posted at this address: http://www.eea.europa.eu/themes/biodiversity/document-library/nationally-designated-areas-cdda/
Please export your data to xml files, upload them and check the results of the automatic QA
Your quality checked 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 2015.
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:
The update of automatic quality assurance (QA) procedures for the CDDA data will be done by the end of January or early February. We therefore kindly ask you, if you manage to finalize the update of your CDDA data earlier, please, postpone your deliveries to later dates in February or to March.
Once updated, the automatic QA will check the following data quality indicators:
The automatic QA service requires that you upload your data in xml format. You get them by using the 'Generate XML files' function in your template. It will create one file per table. Please zip the files and upload them to the CDR together with the MS Access database. The zip archive will be automatically unzipped.
Once you are done, you will notice that a 'Run QA #1' button appears with each of the xml files in addition to the 'Run Full QA' and 'Run relation QA' buttons. 'Run QA #2' will be available next to sites.xml file and will check position of the reported sites coordinates against the respective country boundaries. We recommend that you use these in order to check the quality of your data. The full QA is automatically executed when you release the envelope and results are then stored in the Feedback section of the CDR envelope. If any problems are detected, please try to fix them and redeliver your data before you close the envelope. The more problems you can fix before you release the data, the faster your deliveries can be processed.
A further level of data quality checks will be carried out by ETC/BD data managers and EEA, as usual.
Please consult the revised evaluation criteria for the 2015 data collection
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 2015 data collection have been revised. This was done to improve the quality of digital boundaries data and reduce the time needed for processing. The main change concerns presence of the SITE_CODE now being included as a criteria as well as a reduced number of spatial data files allowed. The detailed specifications are available here, and also in a pdf document which is part of the data package.
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.
We would like to take this opportunity to thank you for your continued support. We look forward to another successful annual data flow.
