Approximate plan looks like this:
- Open input geotiff;
- Check projection and stuff;
- Convert to mercator, if needed;
- Get mercator coordinates from file metadata;
- Calculate mercator tile numbers dictionary for each zoom;
- Generate tiles;

Any help I can provide in this matter? It seems like my previous issue was due to mercator / geodesic tile numbering as well, therefore i got confused even at openlayer.

TLDR: I'm not yet working on that feature.
Long explanation:
Well, I supposes 1-4 paragraphs are pretty easy to implement through gdal library in-code. The difficulties are starting with maths, when calculating tile numbers from mercator coordinates and calculating zones for tiles to read/write.
I haven't yet looked on all that stuff, but I'm pretty sure there's enought info about how-to-do-that in original gdal2tiles.py script.
The point is also not to change too much in GTiff2Tiles.Core existing code, so that'll take some time to implement. I should also change some names because of that (for example RepairTifOptions
enum is needed only to convert tif to geodetic
, but it will be kind of confusing to use that property to "reapair" mercator
tif).
But anyway, thanks for your desire to help!

Logics in GTiff2Tiles.Core
for this feature complete and will be availibale in GTiff2Tiles nuget package starting from v2.0.0-ci436 or higher.
It'll be added to GTiff2Tiles.Console
and GTiff2Tiles.GUI
in next major stable release (2.0.0).
from gtiff2tiles.
As I said above, work in Core for this feature complete and new options will appear in new stable release in both Console and GUI apps.
To avoid confusion, I'm closing this issue.
