[Xastir] using aprsworld maps

[N1OFZ]

I now have xastir running on both OSX and RH Linux 8.0!

I ported over my old MacAPRS maps and they work fine.  I also have 
tried out both terraserver and the tiger maps.  These are great but a 
little slow.  I have a few questions left:

1) I have not had any success with findu.  I created a file FINDU.geo 
with the first line FINDU and the second line N1OFZ per the 
instructions.  I get the error:  Skipping '/sw/xastir/maps/FINDU.geo', 
IMAGESIZE tag missing or incorrect.  Anyone know what I am doing wrong?

2) Has anyone used aprsworld maps with xastir?  I would believe that 
something has been attempted.  I went to: 
http://maps.aprsworld.net/docs/xastir.php and there is some information 
there but I am not sure how it applies.  There is also a map file at 
http://maps.aprsworld.net/mapserver/xastir.map but if I copy it down it 
gives me a whole string of errors.

3) What Internet servers are people using?  I have tried server from 
aprs.net and antelope.net and I get streams fine but I do get 'you are 
an  unverified user, Internet access only.' and 'contact program author 
for registration number.'.  So I am not sure what needs to be done to 
fix this?  Or is this OK?

Thanks,
Dana
