Scope of data harmonization - HB

Hello,

I am a new person dealing with data harmonization. Trying to determine the scope of work on the subject HB.

The sets at its disposal allow to determine the location of habitats, and in attributes the value of the surface and the code consistent with Nature Derective.

These collections include (points and polygons) as well as temporal attribute of the habitat information. The set includes habitat and habitat complexes, distinguished by their observation time. I understand that the above description matches the topic: HabitatsAndBiotopesDistribution, which is suspended, optional, developed for the future? I need confirmation status in the documentation.

In the v4.0 scheme, this set looks like a Habitat that accepts the natural boundaries of the habitat, so at the level of data preparation I am forced to aggregate to EUNIS code - geometry will appear as multi collection like (multi points and multi polygons)? What about the habitat complexes that overlap with individual areas of the habitat, take those that are the latest observations in a given area?

    Dear Piotr,

    the Habitat and Biotopes Distribution is not included in the IRs, it is an ‘additional’ ‘recommended’ application schema in the Technical guidelines and therefore the provision of data encoded accordingly is not required. Indeed, the HabitatsAndBiotopesDistribution schema never got past the draft stage and no news are in the air. You may find more details on this topic in the following INSPIRE Community Forum post https://inspire.ec.europa.eu/forum/discussion/view/261751/habitatsandbiotopesdistribution-xsd

    Regarding provision under the official HB schema, you are not “forced” to aggregate (you can as well provide different spatial objects – polygons or points - for the same EUNIS code) and you can take latest observations in a given area.

    Hope this helps

    Hello Stefania,

    I do not agree with two points of your answer:

    1. "the HabitatsAndBiotopesDistribution schema never got past the draft Stage" is wrong! The data specification was completely finalized and that is why there is no further news.

    2. "the Habitat and Biotopes Distribution [...] is an ‘additional’ ‘recommended’ application schema in the Technical guidelines and therefore the provision of data encoded accordingly is not required." is wrong! The data specification includes a distribution application schema, because distribution maps are required under the reporting on the Habitats Directive. This directive was a major use case for the data specification. The IR was kept "reduced" for other reasons, NOT to indicate, that the content of the TG is "additional" or only "recommended".

    Cheers, Dirk

    Hello Dirk,

    the terms "approved" and "draft"  referred to the application schemas respectively in the IR (repository https://inspire.ec.europa.eu/schemas/) and only in the TG (repository https://inspire.ec.europa.eu/draft-schemas/), are taken from what officially stated in the INSPIRE Knowledge base data model section , in which the following, among others, is stated "Please note that the extended data models not included in the IRs should be considered as draft and therefore be used with caution.

    Regarding the news, I was referring to the moving of the distribution application schema from the “draft” repository to the official repository of approved application schemas. As written also in the linked post, the current HB distribution schema (as well as all the schemas in the draft repository) does not reflect the changes introduced in the amendment of the Implementing Rules (Commission Regulation (EU) No 1253/2013) and the corresponding Data Specification Technical Guidelines that led to the creation of  v4.0 of the “ approved” schemas and presents some minor issues that need to be fixed.

    No doubt that “the data specification includes a distribution application schema, because distribution maps are required under the reporting on the Habitats Directive”, but the data model according to which they are currently mandated is not the INSPIRE one! Data provision that is mandatory under INSPIRE is currently only the one according to the HB approved schema. That’s why HB distribution schema is defined as “additional” and “recommended”. The HB Data Specification (Section 5.1.2) state that “In addition to the application schema listed above, the following additional application schema has been defined for the theme Habitats and Biotopes: HabitatsAndBiotopesDistribution application schema.... additional application schemas are not included in the IRs. They typically address requirements from specific (groups of) use cases and/or may be used to provide additional information

    That said, I absolutely agree with you that the HB distribution schema could and should be used to provide Article 17 data under INSPIRE, as it fits much better the use case needs, but that’s different from saying that it is mandatory.

    Hope this clarifies

    For the sake of completeness, it might be worth commenting a little bit on the statement "The IR was kept "reduced" for other reasons, NOT to indicate, that the content of the TG is "additional" or only "recommended":

    no doubt that following the Technical Guidelines is essential to ensure interoperability of spatial data sets and services. However, all the INSPIRE Data Specifications include a "How the Technical Guidelines map to the Implementing Rules” section in which it is made clear that “Technical Guidelines define how Member States might implement the requirements included in the INSPIRE Implementing Rules”. The Technical Guidelines provide practical guidance for implementation that satisfies the (legally binding) requirements included in the Implementing Rules (highlighted as “IR Requirement”) and contain as well technical requirements that must be met in order to be conformant with the relevant IR requirement (when using the proposed implementation)  highlighted as “TG Requirement “.

    In addition to IR and TG requirements, the Technical Guidelines also include a number of recommendations for facilitating implementation or for further and coherent development of an interoperable infrastructure, whose implementation is not mandatory.

    Coming back to the HB distribution schema, the HB Technical Guidelines place it in the Section5.1.2 Additional recommended application schemas”.

    Kind regards,

    Stefania
