Thanks. I had already used the factor of 5 to modify the lengths. I just wondered if
maybe there was a different measure I didn't know about.
As for the South Carolina Deeds, I have done most of my work with Texas deeds where we
have a verbal description of the deed. I was able to enter my father's-in-law deed
and the output of DeedMapper followed the creek on the topo map I used as a base.
South Carolina is the first place where I have worked with deeds like this. In most cases
I can get an idea of the direction based on waterways and adjacent property, but not

Subject: Re: [DMU] Entering Deeds From A Plat
Look at the 1784 plat. If the sides of the parcel are an inch or less in
length the problem is with the 630 acre figure. If the sides of the 1784
plat are 4 inches or so the problem is with the 20 chains per inch figure.
630 acres divided by the 25.2 acres you actually got shows the parcel is
exactly 25 times too small. That means there's a length error of 5 to 1
(using the square root of 25). If you lengthen each line by a factor of 5
you'll get 630 acres but the scale would be 4 chains per inch, not 20.
The 5 to 1 length error (25:1 area error) is a puzzle.
Regarding upside down plats (something that South Carolina plat drawings
specialize in!), there's no way to know whether to go clockwise or counter
clockwise when entering the calls. There's an email thread about this:
