I'm concerned about whether ground surface distances are different between
NAD27 and NAD83. I'm in California (southern) and thinking about a 
of a project to NAD83. I have some cross section distances measured (1000 to
3000 feet in length) and suddenly am wondering what sort of differences 
be involved by this change in systems.

What can I expect here?
