Hi John:
While I have returned from my travels over the first part of this holiday week, my available time and capacity for looking into these latter development issues related to your project, has been limited by a need to attend to other ongoing personal commitments, in addition to recuperating from some inter-current health issues.
FYI: I have been endeavoring to see if use of
GeoViewer ('free' version rather than the "
Pro" version) in conjunction with SBuilderX, may obviate your need to utilize a discrete freeware or payware GIS application to convert your Mr.SID source files (which would otherwise entail opening yet another entire '
Pandora's Box' of learning).
AFAIK, SBuilderX 'should' be able to display GeoTIFF imagery loaded via Add Map > From Disk as a "MAP" (like downloaded tiles); selected tiles 'should' then be output as a 1-piece BMP and a 'paired' Geo-referencing *.TXT file to:
[SBuilderX install path]\Tools\Work sub-folder
CAVEAT: SBuilderX aerial imagery 'MAPs' must have a name prefix of "
Photo" to be compiled to BGL.
FYI: SBuilderX does
NOT offer the "
Coordinates Tool" that is otherwise available in
SBuilder for FS9 (aka: "
SB9").
See: SB9 Help File > Contents tab > SBuilder Reference > File Menu >
Coordinates Tool
However, assuming one can successfully display a GeoTIFF imagery loaded via Add Map > From Disk as a "MAP" in SBuilderX' work-space, then output as a 1-piece BMP, one 'should' be able to "
Convert" the BMP from its native Coordinate Reference System (aka "CRS") to that required by SDK Resample:
Geographic (Lat-Lon) /
WGS84 ....using the "
Coordinates Tool" in SBuilder for FS9.
It 'should' be possible to load that SB9-converted BMP as a "MAP" in the SBuilderX' work-space via Add Map > From Disk.
One can then use that '
non-warped' Background Image 'MAP' to create any desired scenery content in proper alignment.
If you find that you are unable to achieve a successful work-flow via the above described method, before considering use of a payware "Pro" version of
GeoViewer, you may wish to consider another work-flow using a 'freeware' GIS utility.
It is possible to use the 'free' demo of
Global Mapper version-13 (aka "
DLGv32_Pro" previously distributed via USGS / NASA) to read the internal Metadata of your Mr.SID source files in their 'native' UTM Zone-10 / NAD83 projection.
You could use
Geographic coordinate 'equivalents' for a 'native' source CRS of
UTM Zone-10 / NAD83, read via:
DLGv32_Pro Menu > Tools > Control Center > [Metadata]
button > [Metadata]
tab > [
Copy to Clipboard]
button
...to construct a custom SBuilderX-preferred Geo-referencing 'world' *.TXT file that would be used
instead of the paired Geo-referencing 'world' *.TFW file output by
GeoViewer.
BTW: The 'free'
DLGv32_Pro allows loading and reading of GIS files and their metadata, but
does not allow output.
By using the correct projection source [
descriptor] tag in a custom SBuilderX-preferred Geo-referencing 'world' *.TXT file created within
ex: Windows NotePad, you should be able to Add Map > From Disk, that GeoTIFF output by
GeoViewer as a
non-warped "MAP" in the SBuilderX' work-space ...semi-automatically, without a need to 'Calibrate'.
NOTE: The GeoTIFF output by
GeoViewer and its custom SBuilderX-preferred Geo-referencing 'world' *.TXT file (its filename matching the GeoTIFF filename, but with a *.TXT file extension
rather than *.TIF) ...
must be located in:
[SBuilderX install path]\Tools\Work sub-folder.

Hope this helps with exploring additional options for making your scenery package eligible for public distribution ...
with accompanying aerial imagery for your project area.
PS: I am likely to to be traveling again over the New Years holiday weekend, but I shall look forward to seeing your further progress with the development process.

) you could have been 'snow bound' for all I knew.
