DeedMapper Users: Thanks to those who have been willing to respond to my beginner questions. I am entering data into DeedMapper from microfilmed copies of plats made in GA during the late 1700's. The lines on the plats are marked with a heading and then a number presumably indicating distance, but there is no unit of length after this number. The scale is given for each plat though--usually 20 chains per inch. So I am assuming that the unit of length used in these plats is the "chain." The last two digits of these numbers seem to be separated from the rest by a small space, and in the plats I have looked at so far they are always either 00 or 50. I assume that this two digit number indicates "links." However, when I enter these distances as chains and links, while the plat generated by DeedMapper generally has the shape of the plat on the microfilm, the ending point fails to close with the beginning. Another problem is that the measurement of area generated by DeedMapper is greater than that indicated on the plat. Can someone could tell me whether or not I am correct in assuming that the units of length used in these plats are probably "chains" and "links"? Thanks for any assistance. Leo Leonard
