Hi All,
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.
The profile is in JSON with all the detail gdal2tiles would require to
create tiles (example:
https://github.com/OSGeo/gdal/blob/master/gdal/data/tms_MapML_APSTILE.json
<https://github.com/OSGeo/gdal/blob/master/gdal/data/tms_MapML_APSTILE.json>)
This follows the JSON encoding of the OGC Two Dimensional Tile Matrix
Set specification:
https://docs.opengeospatial.org/is/17-083r2/17-083r2.html
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?
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.
Thanks!
Brent Fraser
