But that does not really answer the question.  How is Tiger data to 
be merged with previously uploaded data for a county?  I am working 
mainly within a single county in Maryland.  I have already spent some 
hours working on roads of all levels.  Will this work be wiped 
out?  Will the Tiger data (which seems to be very extensive) not be 
utilized for the roads already entered?  Or does the process provide 
for preserving the info already entered and adding the Tiger data?

Is there anything that we as individuals can do to assist with the 
upload of the Tiger data?

Oh, and how do we contact D. Hansen?
