The two words that say creativity is dead are "Best Practices". In my
case, I don't care! ;-) Enjoy mapping. If what you are mapping takes you
into a large area of work, then don't worry about it. Part of my answer is
based on the density of mappers in my region and the US in general. I've
been know to map for 12 hours in one change set. I've had two conflicts in
six years. Both of them were very odd and edge cases in my experience. I
have never thought about the size of the area that I map. By all means
leave a change set comment. You are communicating with other mappers. I
found that the change set comment is a frail thing. It may not always
cover the mapping at hand regardless of the size of the area. I will also
add note tags to features. There are times where I cannot survey an area.
If there could be a question of why I made the change or why I split a way,
then the note tag becomes a mini comment about that decision. It is also
another form of communication. I forgot who mentioned this on the list, but
if there is potential issue about a road that was removed because of
construction, then I will draw in a way and add a note tag explaining the
issue. That way this whole pointless issue of arm chair mapping verses
survey mapping is removed from the joy of mapping!
Remember: have fun! Mapping takes you into the spatial part of your
brain. The logical side of your brain takes a rest. That is the best part
