Deed parser (metes and bounds)
Turns pasted metes-and-bounds deed text into a table of calls (bearings, distances, curves, and monuments) for you to confirm and edit before anything is plotted.
Experimental: not yet fully verified. How results are checked
Found 4 calls. Check each one against the deed before plotting.
- Calls 4 have no bearing and distance (a monument, adjoiner, or natural boundary). They are kept as text; add a bearing and distance or leave the figure open.
| Kind | Direction | Distance | Monument | Source phrase | Flags |
|---|---|---|---|---|---|
| line | S 0°15'00" E | 150 ftUS | an iron pin | S 00°15'00" E 150.00 feet to an iron pin | |
| line | S 89°45'00" W | 100 ftUS | South 89 degrees 45 minutes West 100.00 feet | ||
| line | N 0°15'00" W | 150 ftUS | N 0-15-00 W 150.00 feet | ||
| non-metric | along the centerline of Mill Creek to the point of beginning | NON_METRIC_CALL |

- Model
- Calls split at each "thence"; quadrant bearings in symbols or words, lengths in feet, chains and links, rods, varas, or meters; curves by radius, arc, delta, chord bearing and chord
- Accuracy
- A parser, not an interpreter: every call must be confirmed against the deed. Nothing is computed until you confirm the table.

How we got thisFormula, worked example, sources, and proof
Model: Calls split at each "thence"; quadrant bearings in symbols or words, lengths in feet, chains and links, rods, varas, or meters; curves by radius, arc, delta, chord bearing and chord
Accuracy: A parser, not an interpreter: every call must be confirmed against the deed. Nothing is computed until you confirm the table.
Worked example: A four-call lot. Source: Constructed example exercising symbol, word, and dash bearings and a natural-boundary call (Brown's Boundary Control, ch. 5 call forms).
