You may note as well that one of the above cited Alesund addons has placements for 3D model objects in addition to scene object tile arrays.
I finally found my work file(s) from ENSX Stavanger, and saw how I derived the Geographic coordinates.
This may take some time to replicate for Alesund, as I test the coordinates derived from consolidation of data via (2) sources.
While I normally would not mind just deriving the required info and simply conveying it to you, you're likely to need this workflow in the future.
Until we have a better / easier updated method, to derive the Geographic coordinates in alphanumeric text, we can get them via (2) utilities.
Otherwise, you will have to transcribe 32-character long strings for object GUIDs from MCX without making mistakes because they are not text.
*
MCX (Current 1.8 version preferred) - to load local ENAX
objects.bgls from the Alesund addons, and verify info via Object Information dialog
*
BGL2XML Gui version 1.10 - to load local ENAX
objects.bgls from the Alesund addons, and decompile / output placement XML
Download BGL2XML Gui version 1.10 here:
https://www.fsdeveloper.com/forum/threads/bgl2xml-gui-v-1-10.448225/
We'll need to confirm that BGL2XML Gui version 1.10 has the DLL updated from Patrick Germain to enable de-compilation of MSFS 2020 BGLs.
You'll also need the (2) Alesund addons un-zipped into folder chains using
ex: 7-Zip
You can do your derivations with Windows Copy+Paste, NotePad as intermediate data repository, and Windows Calculator in Scientific mode.
Later you can make a basic spreadsheet (MS-Office Excel, Corel Quattro Pro, Open / Libre Office freebies etc.) to do calculation grunt work.
If you would like to learn how to get the data you need for the ModelPart sub-tile RefPts, we could do that interactively to allow questions.
You are 6 Hours ahead of me into your day, so I'll post some initial info in the next few minutes before I must attend to some commitments.
Then I can resume posting again around 8:30 - 9:00 PM in your time zone ...if you wish to connect that late.
If not, I shall endeavor to post more later on this evening, and tomorrow morning ...as time / endurance permits, so you can learn this workflow.
Let me know how you wish to proceed.
