It's clear that a small team of 14 people will not know all the country in detail, but knowing the general conditions/setting still is helping a lot when judging the outcome of your ai tracing.
Out of all the questions regarding the import I must say this is most 
surprising one. With that one statement you undervalue all the work that 
has been done by the thousands of mappers throughout the years with 
number of HOT initiatives. Most of the people taking part in those 
efforts never been to the places like Nepal and relayed only on the DG 
images to help out rescue efforts. Work that FB did is just as good as 
all those efforts with the only difference that machine program prepares 
the preliminary data set to be than verified by the group of people for 
actual correctness. If we are proud of the HOT efforts which may 
introduce number of errors as they are done in haste why would we not 
accept more carefully prepared work initially based on the same source?

IMHO more data is always better than less even if it is not 100% acuate 
although I agree connecting roads just because they are in close 
proximity is problematic and may be wrong. However if there one person 
among us whom in the forest didn't at least the once place a path of 
which present existence they where not entirely sure let them be the 
first one to throw the rock.
