1. INSPIRE harmonization of dataset, an example
Marianne B. Wiese Cand. It System developer

2. Jordartskort (Soil map) 1:1m must be provided as an INSPIRE data service

3. Every legend unit has a code and a description:
Ex.:
F: Freshwater formation (Danish: Ferskvandsdannelse):

4. GEUS contribution to OneGeology
OneGeology Europe is an European cooperation that collects and exhibits geological data.
In connection with a new publication of OneGeology, it was made possible for the participants to exhibit data as an INSPIRE compatible service.
A general guidance was created for all the participants to use. The British Geological Survey did the task as a contribution to JRC

5. Cookbooks that can be used for the conversion of OneGeology-Europe web services to INSPIRE web services

7. Every legend unit must be translated to 5 INSPIRE attributes:
Units from Jordartskort (Soil map)
INSPIRE attributes for geological maps
Description
Age

8. For every attribute exists an INSPIRE codelist
Ex: Geologic Unit

9. INSPIRE codelist for geology:
Is quite comprehensive
Is built hierarchically
Can contain multiple levels (7)
Has varying detailing
Is defined by specialists
Contains redundant information
Is difficult to get an overview of

10. The geologists opinion:
The INSPIRE classification is completely different from GEUS’
The INSPIRE codes should not be mixed with the codelists made by GEUS
INSPIRE codelists needs to be written in spreadsheet to give a better overview
There is over thousands of hours work in a correct transcoding

11. The responsible at GEUS thinks that . . .
It is possible to download INSPIRE codelists in different formats
It is possible (manually) to structure a codelist hierarchically in the JSON format
Then every codelist can be exhibit as an ”tree-structure”, that folds out

12. Visualization of codelists helps the understanding of it:

13. The geologists with the responsibility can now easily contribute by choosing the best terms from the INSPIRE codelists

14. GEUS’ Jordartskort (Soil map) can now be published as an INSPIRE service with standardized color-codes

15. Harvested INSPIRE data is also presented via EGDI EuroGeoSurveys' European Geological Data Infrastructure Portal

16. So far so good, BUT:
The used INSPIRE codelists are a snapshot collected from the official site in spring 2016.
JRC is still refining the INSPIRE codelists.
It would be smart if INSPIRE offered all codelists as a hierarchically JSON document. That would make it easy for all data providers to visualize the currently valid codelists, and so make harmonization easier.
