Log.txt reports missing DSF files, not to be found anywhere

Question

My Log.txt reports that the following dsf files are missing (-44+174,-45+172,-45+173,-45+174)

I can not find these anywhere and would like to know what function is actually calling for these files.
I don't know what geographic area they represent precisely, other than some where in the South Island, NZ.

The same files also don't exist in my XP10 installation and are NOT being called as no errors are being logged in the XP10 log.txt

Can anyone explain where to get these files, or what is calling for them and turning that off.
Not a game stopper just annoying and I wonder if this error is contributing to the extended stopping of loading when starting Xplane 11.

Any and all info appreciated

Answer 1

Default scenery dsf files are located in Global Scenery > X-Plane 11 Global Scenery > Earth nav data. The folders inside there are divided into 10x10 degree tiles. So -45+173 should be in the -40+170 folder. I do not see them in my scenery folder as well, so its possible these were missing in the first scenery cut for X-Plane 11. There will be another scenery cut before X-Plane 11 is final that will include more missing scenery. (Scenery above 70° N & Latitudes was not included due to size issues initially.)
