<div>Hi All,<br id="isPasted">
<br>
I'm interested in experimenting with creating tile sets in
various coordinate systems (other than the usual EPSG:3857 and
EPSG:4326). The good news is that it looks like as of GDAL
v3.2 gdal2tiles.py supports a "profile" option for defining
the tile set including the coordinate system.<br>
<br>
The profile is in JSON with all the detail gdal2tiles would
require to create tiles (example: <a target="_blank"
rel="noopener noreferrer"
href="https://github.com/OSGeo/gdal/blob/master/gdal/data/tms_MapML_APSTILE.json"
moz-do-not-send="true">https://github.com/OSGeo/gdal/blob/master/gdal/data/tms_MapML_APSTILE.json</a>)<br>
</div>

This follows the JSON encoding of the OGC Two Dimensional Tile
Matrix Set specification:

I suppose I could create a profile JSON file by hand (or do
some coding) but I thought I would ask if there was an
existing tool?<br>

Not that I'm aware of. A few lines of Python should be enough to
create a profile with zoom levels varying by a factor of 2 for the
resolution, which is currently a constraint for the profile to be
accepted by gdal2tiles.<br>
