Hi again:
I shall look forward to downloading the SKP file of the current build state for ENKH when you get a chance.
FYI: As described in prior posts above, although WGS84 / EUREF89 - UTM
33 is somewhat useful for 'less warped' maps, one may get 'closer' to an optimal 3D modeling cartographic projection by setting Hoydedata maps to WGS84 / EUREF89 - UTM
32.
However, there are still significant differences between WGS84 / EUREF89 - UTM32 vs.
EPSG:3857 projection for 3D modeling.
I suggest using
SBuilderX to download / output a
BMP satellite image that is in
EPSG:3857 projection for 3D modeling.
Using SBuilderX' Add Map > From Background feature
1.) Install SBuilderX
2.)
SBuilderX Menu > Edit > Edit
(SBuilderX) INI File
a.) In
NotePad, set
ReprojectMercatorTiles to
FALSE > Save that edit > Return to SBuilderX' work-space
3.)
SBuilderX Menu > File >
New Project
a.)
Project Name:
ENKH_Helipad > [OK] button > Return to SBuilderX' work-space
4.)
SBuilderX Menu > Edit > Tile Servers >
Select Tile Server name > select: Google_api3_satellite
a.)
Check checkbox to confirm that choice of Tile Server > [OK] button > Return to SBuilderX' work-space
5.)
SBuilderX Menu > View >
Show Background (F1) <
Imagery begins to appear in work-space >
a.)
SBuilderX Menu > View >
Go To Position > Latitude:
58.164156 Longitude:
7.981848 > [OK] button
b.) Use Magnifying Glass Tool on Icon Toolbar to Center- and Zoom in- on desired area for Background Map
NOTE: Once centered on ENKH Hospital Campus,
Zoom to level 17 using Mouse Scroll Wheel
6.)
SBuilderX Menu > File > Save Project As >
a.)
File Name:
ENKH_Helipad.SBP > [Save] button
7.)
SBuilderX Menu > File > Add Map > From Background
a.)
Tick: Number of Tiles radio button to set Grid size; '
tick':
88 x 96 at Zoom = 20 / (Number of tiles = 4928)
b.) Click+Hold Left Mouse Button to draw a
Red rectangle over
Green grid lines to select desired tiles (
disregard at ENKH)
c.) < Tile download status message appears > after initial tile download is done >
click: [
OK] button again
8.) When tile download is completed,
'Selected' Background Map tiles appear in SBuilderX Work-space
9.) SBuilderX writes a
1-piece *.BMP image and a
*.TXT Geo-referencing file ...into:
[SBuilderX install path]\Tools\Work sub-folder
NOTE: [
alpha-numeric name prefix ] of the BMP and TXT may vary with world location
and Zoom level of Background Map.
In this case at ENKH, it 'should' be "
L20X1095032X1095119Y629808Y629863.BMP"
You should now have a SBuilderX project with a precise background satellite image for making vector scenery objects.
If exported as ESRI
*.SHP files, these can import to MSFS SDK DevMode GUI as 'Primitives' to be edited into Polys / Rectangles
You should now also have a precisely Geo-located, sized, and proportioned background satellite image for 3D modeling.

In Sketchup: Draw a
non-Rotated Rectangle on the ground
ex:
575 Meters Wide x 525 Meters High
a.) Sketchup Menu > File >

b.)
Browse / Select: [SBuilderX install path]\Tools\Work >
L20X1095032X1095119Y629808Y629863.BMP > Click: [
Import] button
b.) Sketchup GUI >
Paint Tool > Left Mouse Button (LMB)+Hold > Drag to NE corner >
watch for '
Point' inference ; Release LMB
c.) Sketchup GUI >
Pencil / Line Tool > Draw a Line on top NW white roof border of Sørlandet Sykehus Kristiansand building
NOTE: This will be ~104 Meters if mapped properly onto the Face in Sketchup; now we re-size the mapped image / 3D model:
d.) Sketchup GUI >
Tape Measure Tool > Draw a dotted Line on top of that Pencil Line @
NW white roof border of the building
Drag Tape Measure Tool over end of Pencil Line, watch for 'Point' inference, drag Tape Measure Tool to end of Pencil Line
-watch for 'Point' inference at end of line, and hold; Release LMB
NOTE: This will be~ 104 Meters if mapped properly onto the Face in Sketchup; now we
re-size the mapped image / 3D model:
e.) After releasing the LMB, immediately type in the Value Control Box (VCB):
112M, press <
Enter> key
f.)
(Message box prompt pops up): "
Do you want to resize the model ?" > Click: [
Yes] button (3D model is now resized)
g.) Sketchup GUI >
Select / Pointer Tool > click on textured Face to 'Select' it
h.) Sketchup GUI >
Tape Measure Tool > Draw a dotted Line at both Vertical and Horizontal 'Midpoint' inferences of the Face
i.) Sketchup GUI > Triple-Click on Face > Right-Click >
Select + Click: "
Make Group"
j.) Sketchup GUI > Triple-Click on Face > Right-Click >
Select + Click: "

k.) Sketchup GUI > "

R-G-B-Y Pins visible - but do not move them):
LMB+Hold >

m.) Sketchup GUI >

n.) Sketchup GUI >

Select + Click: Lock
o.) Sketchup GUI > Window > Model Info > Geo-location > [
Set Manual Location] button
Edit - Geo-location info for
Country and
Location
Edit - Latitude:
58.164156 Longitude:

OK] button
You should now have a precisely Geo-located, sized, and proportioned background satellite image as a Face for 3D modeling.
Let me know how this works for you.

I only use Satelite/aerial imagery for detailing purposes, but not for outlining.
In my mind; if the helipad is where it is supposed to be, how does that affect navigation?
I cannot find any hits in the URL for EPSG:4326 either, so I assume it's okay.
