[GRASSLIST:7742] v.digit oops - backup command

GRASS GRASS user

Ok... so i 'm happily v.digitizing away... and i delete something i
didnt want to, or do some operation i made a mistake on (moved vertex,
etc..).

is there a way to "back up"? in other software it keeps an audit trail
of transactions and you can "oops" back through all the transactions,
in effect restoring vector digizing operations performed....

is there something similar in GRASS v.digit?

thanks!

I have never heard of something like this, though it would be most welcome. I always make a copy of the vector that I am going to digitize, and work just on the copy. Once I am done, I then erase the old file. Primitive, but it saves me from some of my mistakes.

Cheers,

i see... but if you have hundreds of edits and u make the mistake at
change 50... then u have to revert back to the previous copy and start
all over? seems like alot of lost work at that point :frowning:
