we just received some shapes accompanied by an xml and no prj.
So far I was out of luck finding the proper projection for this, but I'm
guessing that this stuff is from Manifold (my first contact with that)

Can anyone tell me from the xml what would be the related EPSG code for
this data?

<?xml version="1.0" encoding="UTF-8"?>
         <datum>World Geodetic 1984 (WGS84)</datum>

I have not much experience with Manifold, but I guess it should be an
orthographic projection. In that case, looking in the EPSG database may
be useless. You would have to create a custom CRS for it.

Reading and the xml file linked there, it is definitely from Manifold. So lets try:

+proj=ortho +lat_0=0 +lon_0=0 +x_0=4393181.425 +y_0=5437772.5 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

I'm not sure about the difference between false easting and OffsetX. Maybe you have to enter negative values. And localScaleX and localScaleY is strange. Maybe it can be put in +to_meter (or 1/3.175=0.31496?) instead of +units=m.

Can you load the file into QGIS, and post the extent in map units, as reported by layer -> properties -> metadata -> Properties -> Extent?
