Ask the geologist?

Seriously, ask a n actual answerable question: now you want GIS software to distinguish between good and bad geologist?

Hi all
I would to know how to differenciate  GPS field track from GPS track manually generated (cr?ateur) .
I mean that if you send  a geologist in the field, there is one who really does correctely his job un saving track in GPS but there is another one who does not reach the destination and as a result he creates a fake track in GPS . So How can I distingwish the true track with the fake one?

Hi Jean,

I don?t think this is the right place to ask this question, which is a similar answer to Barend. 

I?ve not had to do this, but I wouldn?t be looking much with the GIS Software. The file and its attributes should say a lot. The GPS will say some. What they bring back would also say a lot.
In the end it?s likely still difficult to prove.

Regards,
Ramon.

or try to make sense out of the time-stamps (if the tracks are from 
recent 'return from field' trips)

But yes, question is not answerable without some knowledge of how and 
when the group of tracks your musing over, came to be.
