Good Morning....Okay I will continue where I left out.
Completing Step 1, I now use Global Mapper
http://www.bluemarblegeo.com/products/global-mapper.php
This is a software that cost us $400....you can use a trial version, but you are limited to exports. The value is HUGE what you get with this, the customer care and technical support is outstanding!! Global Mapper, is very powerful as it can generate countless projections and datums.....it will stitch together massive areas of Terrain and Images......there are other techniques and free applications to take care of the re-projection, I am just not familiar with them at this time.

I would reference this forum, if you want to go around Global mapper.
Okay, Open Global Mapper: Very very important step!!
- In Display Settings/Projection, Projection Tab:
Projection: Geographic (Latitude/Longitude
Datum: WGS84
Planar Units: Arc Degrees
(Follow these steps! I spent countless hours trying to figure out why my images and models were not lining up in ADE, 3ds max and Prepar3d, I was uncoachable, I was using my past "intelligence" brought over from my Engineering and Architectural world....I thought I was smarter than all of the Developers in this Flight Sim community....very expensive ego, I had to leave behind)
- Open up folder where your zipped files are from USGS, drag and drop the zipped folder(s) int GM. GM will open up image into correct re-projection. Time to export.
- File/Export/Export Raster/Image Format: geoTiff, enter
Browse to folder, save.
- Time to compile geoTiff, re-sample, ready to compile into .bgl
Step 2 Resample Image for placement into P3d ( Compiles geotiff, places image int the flight simulator or it repaints terrain surface)
Here is a great Tutorial on this entire process, you will see Step 2, in video this is the step I replaced with Global Mapper:
http://www.prepar3d.com/videos-and-tutorials/
- Open a notepad (yes we have some very simple coding to do....don't be afraid, as I was...it is very simple). Copy and paste the below code:
[Source]
Type = GeoTIFF
SourceDir = "SourceData"
SourceFile = "
YOUR.tif"
Layer = imagery
SamplingMethod = Majority
[Destination]
DestDir = "Output"
DestBaseFileName = "
YOUR_Image"
DestFileType = BGL
LOD = Auto
FractionBits = 3
Save this as: (name of imgae.inf)
It is important that this is in the root of the directory which will have 2 folders: SourceData and Output
Now, in your SDK Develpers directory (I will paste the location where mine is, yours may be different, but it will be similar):
C:\Program Files (x86)\Lockheed Martin\Prepar3D SDK 1.4.4747.0\Environment Kit\Terrain SDK
make a shortcut of the resample.exe to your desktop
Here is another training module that helped me understand this process:

Truly this is a very simple process, it can be overwhelming for us new Developers...but trust me....it gets easier with practice...just like anything.
- Once you have the resample.exe shortcut on your desktop, simply drag and drop .inf onto that .exe. The compiler will begin, you will know it is working, as a cmd window will pop up and you will see it crunching away.
- Once complete, a new .bgl is placed in the output folder, this .bgl copy it into your addon scenery folder. Voila, done! Go Fly and check out your new terrain image.
