Dear Bianca,

Thank you very much for your post.

In fact, there is a lot of information which would be really useful to be compared and combined with INSPIRE data sets, as background geospatial layers.

But how to do it when there is no information about the spatial reference (scale, CRS and projection)?

The topic of INSPIRE-like data lacking information about the spatial reference (scale, CRS and projection) is in my view very interesting, since the INSPIRE Directive request always information about this reference.

Hope there is good discussion in this thread about this question.

And maybe someone is also able to help Bianca on guessing the parameters of the Lambert conformal conic projection for this specific map.

Dear Nathalie,

Thank you very much for your question.

Do you have an approximate idea on the month it was discussed by MIG?

Otherwise I will check all the meeting minutes from 2018.

Dear Jordi,

2 paper discussions  has been taken at the MIG-T meeting of April 2018.  One on possible adoption of national CRS and the other one on Web mercator CRS ( widely used).

https://ies-svn.jrc.ec.europa.eu/projects/mig-inspire/wiki/MIG-T_meeting_48

The final conclusion could have been at the MIG the following : no change in the IR and TG, but well a registry of adopted CRS. Candidate CRS should be endorsed by the JRC. But I do not see any registry in that matter.

Sending you the discussion paper.

Kind regards

Nathalie

Dear Nathalie,

Many thanks for this accurate information. 

I will check with JRC for any progress on the implementation of the INSPIRE CRSs Registry. This sould have been pushed by France (Member State that proposed it). 

However, having had a look at the meeting minutes from April 2018, the possibility to use Web Mercator (e.g. Spherical Mercator Grid) as an additional grid system should have been developed and discussed using the good practice procedure. I guess that any progress on this matter is linked to the  potential drafting of this good practice procedure. 

All the best,

Jordi
