      Dear Julian,

      sorry to disagree here. If you read Annex H of the LC data specification, the possible usages of the PLCC code list are:

      a) It can be used simply as a kind of nomenclature, and the LC data is entered into the model by application of the code list like a categorization and attaching only one single code from the code list to a certain land cover unit.
      b) The code list can be used in a descriptive way, which gives room for attaching more than one land cover component from the code list to a single land cover unit, expressing that on a particular spot in landscape there exists more than one land cover component. This application of the code list would go in-line with the idea of the descriptive approach of the ISO standard 19144-2 (LCML).
      c) Use the code list like mentioned in b), in a more elaborated way by not only mentioning more than one land cover component to be attached to a certain land cover unit, but also to enter a percentage value and structure description (like in LCML horizontal pattern/vertical stratum), which indicates the relative fraction and spatial composition of the considered land cover component inside the area extent of a definite land cover unit.

      And when looking at the classes, there are clearly land cover classes (e.g. Broadleaved forest trees or Artificial constructions).

      So I fully support Lena's summary.

      On a related note, in the MIWP-6 sub-group on registers and registries, we are currently setting up a testbed for an INSPIRE register federation that will investigate how to best model and work with national and thematic extensions of central INSPIRE code list (empty or not). The LandCoverClassValue and its extensions (e.g. the recently published Corine land cover classification) will probably be one example we will look at.

      Dear Michael,

      Concepts of LC classes and LC descriptors go further than DS LC can express. Knowledge of it has evolved and matured in last years after DS LC, and go back to proposed PLCC can arise confusions. The PLCC where thought has atomic LC descriptors of the surface, but if you analyze each of them it is possible to identify some LC classes on it. So, the use of this list like LC class values, is not sufficient clear.

      PLCC really atomic LC descriptors: artificial constructions, consolidate bare surface, unconsolidated base surface, coniferous forest tress, broadleaved forest trees, shrubs, herbaceous plants, lichens/mosses, salt/brackish water, permanent snow/ice

      PLCC that represent a complex combination of atomic LC descriptors (real LC classes): arable land, permanent woody/shrubs crops, wetland/marshes, organic/chemical deposits, intertidal flats, water courses/bodies

      But even more important is that LC DS don't motivate to use an unique nomenclature of classes, answered in the annex H question 5.

      Dear All,

       

      Although, I was not directly involved in the TWG on LC as a member, I will try to provide some further comments about the scope, nature and applicability of the pure PLCCs. These comments are based on my personal experience and understanding of the subject.

       

      To my knowledge the reason to propose such PLCC within INSPIRE was partly initiated by EUROSTAT in response to similar activities conducted by United Nation Statistical Division. SEEA has proposed a list of “aggregated structures” based on LCCS to be used to produce harmonized land cover statistics at global scale. They were meant to describe the land purely based on its bio-physical nature (land cover). During the global consultation of the land cover classification, EUROSTAT argued that apart of the FAO Land Cover Classification System (LCCS), Eurostat's work on LUCAS and the work carried out in the LC and LU working groups of INSPIRE should be taken into account. Thus, one of the aims of the Pure Land Cover Components (PLCCs) was to provide the concept and method to describe the European land purely based on land cover characteristics for the purpose of the EU statistics, taking into account not only the LCCS, but the European experience from LUCAS and INSPIRE development. Moreover, PLCCS have to act also as a sort of generalized nomenclature - similar to the SEEA one - which can be used as a generic INSPIRE LC codelist (or even enumeration) to which national LC nomenclatures and products will be mapped in order to derive harmonized statistics on land cover at European scale.  

       

      I was indirectly involved in the discussion about Annex G together with Wim Devos from JRC, who was member of the INSPIRE TWG on LC. We tried to design a stratification of the land, based on generic land cover “primitives”. The list of LC types was meant to be:  scale-independent; flat (all LC types are on the same level of detail); exhaustive and unambiguous (LC types are mutually exclusive). We used the UML model of the LCML, combined with the dichotomous approach of the LCCS, by starting this list from the most generic (upper) level of the model with only two main land cover types (biotic/abiotic) and further sub-dividing them by adding land cover classifiers (elements) while going step-wise at lower (more detailed) hierarchical level of the LMCL model. The process was not always straightforward as LCML concept is different than the one applied in the LCCS. I believe part of all this work was used for the design of the PLCCs currently present in Annex G; although the resulted list in the INSPIRE DS is quite different than what we have proposed.

       

      In this respect, I can agree with Michael, that the current PLCC list looks both:

      1. as fixed nomenclature to be applied a one single code for every land cover unit, and
      2. as a set of LC “primitives” used to describe the different land cover components inside the land cover unit, in similar way as SIOSE.

       

      However, I agree also with Julian, that adopting the PLCC as official INSPIRE codelist is not advisable, as knowledge on land cover semantics already evolved and matured, and there are new developments in this respect (EAGLE project, TEGON model) that needs to be considered before such decision is taken.

       

      best regards,

      Pavel

      Hi,

      Is there or will there be support for other languages in the CLC code list? That is, can we refer to it 1) only by using class labels in English or 2) also by using class labels in for example Finnish?

      Lena

       

    • Christian ANSORGE

      By Christian ANSORGE

      Hej Lena,

      I am sorry but we will not provide the CLC codelist multilingual, also because EIONET Data Dictionary isn't supporting multilingual versions of code lists. 

      The notation and therefore the URI of the values is intentionally chosen to be language neutral. Therefore the codes can be used independent from the actual language and only the labels are in English.

      Best regards

      Chris

      Hi Christian, Michael, all,

      Have you already discussed and reached an agreement on how to handle the CLC code list in general in INSPIRE in the MIWP-6 sub-group on registers and registries or elsewhere?

      According to Michael the CLC code list  published by EEA should:

      If possible, it would be good to put this issue in place together with the exlusion of references to the old CorineValue code list in the TG on LC as proposed here. That is in case this proposal is endorsed by the MIG.

      Best regards,

      Lena
