Data format for checking a land survey deed

Question

A commercial property is in the closing phase of sale and the only hold up is that the deed description is one that's been lifted from prior deeds dating back to the 1950's and is obviously erroneous. A 1992 survey does appear to properly depict what the Seller's have to convey and both Buyers and Seller agree that the aforementioned survey be the basis of description in the new deed and title policy if ...it plots out in reasonable fashion in Copan.

But, after spending six hours trying to get a result (closure error, or an additional call necessary to close) and a graph, I have been unsuccessful. format I've used is:

Map Traverse
1 degrees distance tab tab tab
2 degrees distance tab tab tab
3 degrees distance tab tab tab
1 degrees distance tab tab tab

That produced a bizarre graph, so I tried making the first call

Map Traverse
1 0.0 0.0 tab tab tab

Then I get an error message saying in effect "insufficent tabs" and use cut and paste to provide missing tabs.

The original survey plat:

Answer 1

According to Map Check in Copan User Manual, each call is of the form

to-point bearing distance <blank> <blank> <blank>

as you (sort of) say. However, the first "call" must have (only) the initial start point (and optional label):

from-point <blank> <blank> trav-label <blank> <blank>

In other words, a traverse will look something like this:

1 <blank>  <blank>  trav-1 <blank> <blank>
2 bearing distance <blank> <blank> <blank>
3 bearing distance <blank> <blank> <blank>
:
1 bearing distance <blank> <blank> <blank>

where the last point no. is the same as the start no. (assuming it is a closed loop).

Note: Because each data line must have five tabs, and things must be in the right column (out of six), each "empty" column above is represented by <blank>. Also, the words Map Traverse should not normally appear in the data window; it's "invisible" text that labels the data file. You'd only see it if you viewed the file in a text editor.

Based on your comments, i think you may be getting mixed up between what a whole .MT file should contain (which you normally never see), and what just the traverse lines should contain (always visible in the big edit window). The former includes 7 "invisible" header lines plus the latter traverse data lines.

This is the whole MT file i used:

and this is just the content of the edit window:

1   276.5342     95.62

Try to avoid cutting and pasting of large chunks of data within the edit window; it often leads to a wrong number of tabs per line. And if you're having difficulty with editing text files -- stick to editing individual items within the Copan window. I especially recommend not using word processors for editing text files!

Using the above data, and running Copan's Map Check, here's the text result:

After combining the distance data you provide above, and the direction data you provide in a separate question (how-to-enter-quadrant-bearings-into-copan-map-check), I reran Copan's Map Check:

I tried plotting this in Plat Plotter http://platplotter.appspot.com/

and got an 84 foot / 14% error. Don't know if I copied the calls correctly: the Plat is a little fuzzy. This was my input data:
