Steve, the example of your approach to your Virginia patents is so
Did you go to the National Geophysical Data Center site and figure out
specifically what the values were for Albemarle Co. for the decades listed
below? Or did you just come up with the values on your own?
Both! I probably looked at the numbers for Roanoake and used them for the
overall trend of change. The NGDC numbers only start in 1750, so numbers
to that were determined by experimentation.
Can you explain what you mean by this:
>>3) comparison of properties that abut the county or state line.>>
Some properties abut the county or state line. Suppose the county line is
N40E, but when you put it against the county line you must rotate by 2
to get it to fit. You therefore know there was a declination error of 2
degrees at the time
of the survey.
If I sorted by Date and then inserted an include item at certain
would the Item Number change for each tract?
Yes, it would
