• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSX Resample.exe Not Compiling

Hi Caleb:

Before we Geo-rectify your files in Global Mapper, we need to know Pixel Row and Column 'size' for each of these images:

* "X10_blendmask_gimp.tif"

* "X10_watermask.tif"


Also, please clarify whether the above images were created from copies of your original DG_Satellite_1.tif GeoTIFF image.

If so, please clarify whether the above images have not yet been 're-sized' by any graphics application, or or 're-projected' by any GIS application such as Global Mapper or QGIS etc ...after they were created as copies of your original DG_Satellite_1.tif.

[EDITED]

I shall await your reply to the above questions prior to proceeding; (I'll require that info to prepare a step-by-step guide). ;)

[END_EDIT]

How may I find out this? Are these the "pixel width" and "pixel height" entries in the metadata in Global Mapper?

I opened a copy of the GeoTIFF in Photoshop and drew the watermasks and blendmask as separate layers in Photoshop on top of the GeoTIFF. After I was done with this I deleted all layers except the blendmask layers and exported it as "X10_blendmask_gimp.tif" (please ignore the "gimp" part of the name). Then I deleted all the layers except the watermask layers and exported them as a separate tif (X10_watermask.tif) as I did with the blendmask.

Click to expand...

No, "pixel width" and "pixel height" entries in the metadata in Global Mapper are Pixel Dimensions per unit of measurement.

In Universal Transverse Mercator (aka "UTM"), Zone 17 (Northern Hemisphere) we use Pixels per Meter

In Geographic (Lat-Lon) Projection / WGS84 Datum (aka "EPSG:4326") / Units=Arc Degrees, we use Pixels per Arc Degree


The Metadata in Global Mapper pertains only to an image that is Geo-rectified and opened as a 'layer' in Control Center.

We can 'best' be certain as to the actual Pixel Row and Column 'size' (and the Pixels per unit of extent on the ground) for each of these images after they are properly Geo-rectified in Global Mapper and opened as a 'layer' in Control Center.


FYI: To see (but in this case, not change:alert: ) a current actual Pixel Row and Column 'size' for your Mask images, refer to this:

https://helpx.adobe.com/photoshop/using/image-size-resolution.html


Please post current actual Pixel Row / Column 'size' for each Mask image in a reply; we will be better prepared to proceed with Geo-rectification.

Thanks for the reply. I'm going to be away from my PC for the next few hours also, so I will wait for your guide and send some screenshots as soon as I'm back at my PC.

Thanks for the help.
 
Ok so I'm back at my PC. Here's a bunch of screenshots of the messed up watermasks.

Example Global Mapper workflow to Geo-rectify the Blend Mask for your aerial imagery: :teacher:

NOTE: This is intended to match your Blend Mask image Geo-rectification to that of the 'native' Geo-rectification assigned to your original DG_Satellite_1.tif" GeoTIFF "DAY" image file when it was first opened in Global Mapper.

After properly Geo-rectified, the Blend Mask image must be "re-projected" within Global Mapper to the "projection" required by MSFS / P3D SDK Resample ...so that any subsequent exported data will be correctly formatted:


First, unload all open files from the Global Mapper work-space:

1.) Global Mapper Menu > File > Unload All...

2.) Global Mapper Menu > File > Rectify (Geo-reference) Imagery... (Batch Image Rectification Options dialog opens)

a.) In "Batch Image Rectification Options dialog":

(1) Check: "Add Rectified Images to Main Map View"

(2) Check: "Show Rectified Images in Reference View"

(3) Check: "Export Rectified Images to New Files"

(a) Tick: GeoTIFF > Pick: Grayscale Palette

(b) Click: [OK] button ("Open" dialog pops up)

(c) In "Open" dialog > Browse / Select: "X10_blendmask_gimp.tif" ("Tip" dialog opens)

Thank you very much for catching my unintended editing error; Planar Units for UTM should indeed be Meters. :eek:

I have edited my posts above in this thread to correct Planar Units to Meters for cited UTM projection info. ;)

Now I must find / edit my other posts elsewhere in the forum containing that same editing error (perils of copy-and-paste !) :banghead:


UPDATE: My (1) other post found elsewhere in the forum, containing that same editing error, has also now been corrected. :pushpin:

I'm still working on the blendmask, and the above step gets me confused. How do I "configure: Top-Left (NW corner) pixel"? Would you mind explaining this a little deeper?

And after I've done that, do I manually enter the "PixelX", "X/Easting/Lon", and "PixelY" as you told? Or am I supposed to click somewhere and let it automatically enter that info for me?

Thanks.

For the Upper-Left (NW corner) pixel:

* Accept the existing correct "0" value for both "PixelX" and "PixelY" Pixel 'coordinate' positions

* Click into each empty alphanumeric character entry box to enter the numeric values shown in a bold typeface :

X/Easting/Lon: 532999.623

X/Northing/Lat: 2956194.610


For the Lower-Right (SE corner) pixel:

* Click into alphanumeric character entry box to Delete existing in-correct "0" value for both "PixelX" and "PixelY" Pixel 'coordinate' positions.

* Replace both "PixelX" and "PixelY" Pixel 'coordinate' positions with:

PixelX: 11068

PixelY: 20640


* Click into each empty alphanumeric character entry box to enter:

X/Easting/Lon: 536320.023

No, that does not look correct, as the Red cross-hairs should be at the:

* Upper-Left (NW corner) pixel

...and:

* Lower-Right (SE corner) pixel


FYI: I had made yet another editing error by incorrectly stating "Bottom-Left (SE corner) pixel" (more perils of copy-and-paste !):duck:

That statement is now corrected above. :pushpin:


< Time for my coffee break, apparently ! :rotfl:>

Let me know if the latter correction resolves the issue.

That's what I thought was wrong. That's why I posted to confirm. I think I was clicking around a bit to try to figure it out and messed things up, so I will redo the process tomorrow.

I'm actually not sure if my watermask is a 8-Bit grayscale TIF file, but the current size (before being Geo-rectified / re-projected) is 871 MB.
 
OK, we'll see how things work tomorrow. :)

If necessary, perhaps you can PM a link to your Water Mask TIF inside a ZIP file (ex: DropBox ?) so I can download it for inspection. ;)

FYI: WinRAR and 7-ZIP can 'segment' a big file into smaller pieces to be reassembled ...to work-around file size limits of download sites. :idea:

I am still at the step I quoted above for the blendmask, and when I enter the things you say, the point still does not appear in the far upper left corner as you said it was supposed to.

Where did you find out the numbers that I should put in the "X/Easting/Lon" and "X/Northing/Lat" fields? Maybe I incorrectly specified some information that you used to calculate these numbers. Can you please tell me how/where you found the information for the "X/Easting/Lon" and "X/Northing/Lat" fields, so that I may confirm that I correctly specified the information you used to calculate those numbers?

Thanks.
