Hello!
I totally agree with Sebastian. These data is surely geo-referenced, as
I myself often used in the past data from USGS. Locking at the metadata
you provided I would say that you are in an EPSG:2238 Lambert Conformal
Conic projection, which is the main projection system for north Florida.
You may try to specify to GDAL the source projection using this EPSG code.

Christian

Hello!
I try to build map using vpb in ECEF.
According to manuals i've read it needs to start:
vpbmaster --geocentric -t texture_file -o output_file
So, clearly i need georeferenced texture file.
On that page:
http://www.osgvisual.org/projects/osgvisual/wiki/OsgTerrainData
there is a bunch of links to get data. Since --geocentric option
allows not to use elevation data, then only textures are needed.
Who told you this? Of course you can use elevation data in geocentric
mode ...
Simply use -t for imagery and -d for digitial elevation data
And here is a problem: i can't get georeferenced textures from USGS.
They are referenced, but in a non-supported coordinate frame. I never
had problems of this kind yet.
But there are definitively geo-referenced data-sets on USGS, as I'm
using them myself.
Use LandSAT imagery, which is WGS84 projected, so there should no
problems here.
If you need some sample data I can share a small set on googledrive etc.
All files i choose from different sets there are without
georeferenced information.
gdalinfo output:
...
Yes it seems there is no valid projection. But still the data is
referenced.
What am i doing wrong?
Without having your data, this is hard to tell
Thanks a lot and best regards!
Elias
