Land
Deeds, legal descriptions, and old units.
Boundary work from the record: reading metes-and-bounds deeds, plotting their calls with closure and area, rotating bearings to a new basis, reading PLSS legal descriptions, converting chains, rods, and varas, and checking relative positional precision under the 2026 ALTA/NSPS standards. Start with the deed parser, then the deed plot. A deed plot shows what the document says, not where the line is on the ground: monuments and calls for adjoiners usually control over bearings and distances, and that is a surveyor's judgment.
I want to check a survey against the ALTA/NSPS precision standard
- ALTA/NSPS relative positional precision
The allowable relative positional precision between two adjacent boundary corners under the 2026 ALTA/NSPS standards, compared with the 95% error ellipse from your adjustment.
I want to read a metes-and-bounds deed and plot it
- 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.
- Deed plot, closure, and area
Plots confirmed deed calls (lines and curves), then reports the misclosure, its direction, the precision ratio, and the area closed by the implied closing line. Courses are never adjusted unless you choose to.
I want to rotate bearings to a new basis
- Basis-of-bearing rotation
Rotates deed or plat bearings to a new basis of bearing (like grid north) from one line whose bearing is known in both, and reports the rotation angle.
I want to read a PLSS description
- PLSS legal description reader
Reads a Public Land Survey System description like NE¼ SW¼ Sec 12, T3N R4W, 6th PM into plain words, and gives the nominal aliquot area of a standard 640-acre section.
I want to convert chains, rods, links, and varas
- Legacy land units
Converts chains and links, rods, furlongs, varas, and arpents from old deeds and plats to US survey feet, feet, and meters, with the definition used; varas and arpents need a jurisdiction.
From deed to plot
- Read the calls out of the deed text: bearings, distances, and curves. Deed parser (metes and bounds)
- Plot them, check the closure, and find the area. Deed plot, closure, and area
- If the deed's bearings are on a different basis from your survey, rotate them. Basis-of-bearing rotation
Guides that use these tools
- Boundary retracement from a deed: Read the calls out of a deed, plot them and check closure, then rotate the bearings to the basis you found in the field.
