Many Metes and Bounds legal land descriptions are simple enough that this fill-in-the-form app will do the job.

What follows is a quick start for the impatient, then a sales pitch, followed by the essential background knowledge on metes and bounds legal land descriptions and finally the detailed operating instructions for this application.

There is a reference section at the end.

Quick Start

Enter your metes and bounds legal land description.

Check will run a syntax check on your data and draw the land parcel. The starting point should meet up with the ending point. This is called "Closure". The acreage should be very close to what is on the legal land description. Syntax errors will be highlighted. Hover over the highlighted fields to see the error message.

Calc does the same as above, but includes latitudes and longitudes for all points.

You can also download the point coordinates in CSV, KML, GPX and JSON formats. GPX can be loaded into your Garmin. KML is used by Google Earth.

Sales Pitch

'Check' is always free. Your first 3 Calc's are also free.

Each 'Calc' consumes 1 credit.

Typically 20 to 30 credits are required to complete a project.

Metes and Bounds Land Description

Overview:

A Metes and Bounds Land Description starts at a well defined beginning point and traces the perimeter of a property using carefully measured distances and angles until it finally returns to the point of beginning.
The end point must meet up with the start point. (Closure)

Example:

A tract of land in the Northwest quarter of the Northwest quarter of Section 30, Township 1 South, Range 66 West of the 6th Principal Meridian, County of Adams, State of Colorado described as follows:
Commencing at the Northwest corner of said Section 30;
Thence South 20°30' East, a distance of 140.60 feet to the Point of Beginning;
Thence North 88°55' East, a distance of 200.00 feet;
Thence South, a distance of 125.00 feet;
Thence South 88°55' West, a distance of 200.00 feet;
Thence North, a distance of 125.00 feet to the Point of Beginning;
Containing 0.57 acres, more or less.

Bearings are based on the north line of the Northwest quarter of Section 30 to bear North 89°42' East with all bearings contained herein relative thereto.

Elements:

PREAMBLE
- The preamble provides a general description of the land to be described including the county, state and other general information to orient the reader.
- The preamble gets the reader to the proper general location.
POINT OF COMMENCEMENT
- This is the reference point.
- A Point of Commencement is used to unambigously reference the parcel to a well-established point (ie: a government survey corner).
- A Point of Commencement is used when the reference point is not on the perimeter of the parcel.
- The Point of Commencement is either inside the land parcel or on another land parcel some distance away.
- There might not be a Point of Commencement.
POINT OF BEGINNING (POB)
- The Point of the Beginning is "pen down", the first point where the drawing of the perimeter begins.
- If there is no Point of Commencement, the Point of Beginning is also the reference point.
BODY
- The Body contains a sequence of Calls.
- These Calls draw the perimeter around the land parcel and end up back to the Point of Beginning.
- Calls recite Courses and Distances.
- Calls can be a straight line, a curve, or a line parallel line to another line.
- Calls can be references to adjoining boundaries, natural or artificial monuments, roads or rivers.
- Courses are the direction of a line.
- Courses are usually referenced to true north, but sometimes are referenced to magnetic north or a Basis of Bearing
- Distance is the length in a well-known unit, such as feet, meters or chains.
AREA
- An Area Call sets forth the approximate acreage in the parcel.
- The acreage in the Area Call should be very close to the calculated area as defined by the sequence of calls in the Body.
BASIS OF BEARING
- A Basis of Bearing is used instead of true north or magnetic north as the reference for the Courses.

Operating Instructions
Field	Description

Project Name	A short description of the land parcel.
Ellipsoid	The Earth is not completely round sphere, it is an ellisoid. The Earth bulges out at the equator, like when a child sits on a beach ball. There are slightly different sets of numbers used to describe the ellipsoid shape of the earth. Some are newer and more accurate. Some work better on a specific part of the earth, like the area around Mount Everest. If unsure, leave this field blank.

Line	Line Number. Line Number is not part of a legal land description. It is used by this application to provide a reference to a specific line of the input form. The Line Number is used to label points on the drawing that do not have a Point Name.
Latitude Longitude	This is the critical starting point used to calculate all the other points. Care and attention are required. Latitude and Longitude to 5 decimal places is about a meter. The Latitude and Longitude are entered in decimal degrees, with Longitude being a negative number in the Western Hemisphere. The MGRS app can be used to convert a Degree, Minutes, Seconds into Decimal Degrees. Sectional In the parts of the United States covered by the Public Land Survey System and the parts of Canadian provinces covered by the Dominion Land Survey, the starting Latitude and Longitude are often corners that can be obtained by using one of our sectional land description converters. Enter the Sectional Land Description and click calc. Download and save the CSV file. Right Click and Open the CSV file with a text editor like notepad. Use notepad instead of Excel, because Excel can round numbers and destroy the accuracy needed in this application. Find the corner in the CSV file that matches the corner in the legal land description. Copy and paste the latitude and longitude into the form above. Government Databases Finding US Survey Marks and Datasheets National Geodetic Survey Physically get the GPS of the Starting Position Devices with a built in GPS chip such as smart phones which can directly receive satellite GPS signals. The accuracy is typically claimed to be within 10 meters. Stand on the starting location (if legal). Use the https version of MGRS converter and click the "Get" button. In 5 to 10 seconds, the Latitude and Longitude fields will be filled in by the GPS technology in your phone. Write down the Latitude and Longitude. The phone may clear the data during a power cycle. Check that the MGRS converter can get a GPS location before you leave home. If "get location" or "allow this webpage to access your location" are turned off in your smart phone's web browser, it can be difficult to turn back on. You can use other devices and other apps to get the GPS location.
Point Name	Name of this point. The Point Name is used by the legal text to name a point that will be referenced later on in the same document. The Point Name is used to label the point on the drawing.
Begin	Point of Beginning. "Pen Down". Drawing of the Perimeter begins.
Courses Courses are the directions to move. This application accepts courses in in 2 formats.
Cardinal	North, South, East and West, Northwest, Northeast, Southwest and Southeast. Cardinal Directions are simply stated as words. Degree, Minutes and Seconds are left blank.
North/South Degree Minute Second East/West	The Compass is divided into 4 quadrants. Directions start at either North or South and proceed at an angle towards East or West. At least one of the degree, minute or second fields must be filled in.
Distance
Length	Length is a positive number with up to 8 decimal places.
Unit	These well know units of length are accepted. Unit Meters ------------- --------------- Chain 20.1168 Link 0.201168 Rod 5.0292 Foot 0.3048 Meter 1 Yard 0.9144 Inch 0.0254 Furlong 201.168 Perch 5.0292 Pole 5.0292 Mile 1609.344 Kilometer 1000 League 5556 US Foot 0.30480061 ------------- --------------- US Survey Foot Since 1893, the legal definition of the foot in the United States has been based on the meter. The definition adopted by Congress in 1866 was 1 US Foot = 1200/3937 meter exactly. In 1959, the relationship of the foot to the meter was officially changed to what it is today: 1 Foot = 0.3048 meter exactly. U.S. Survey Foot (NIST) Although the difference is small, across the distance of an entire state, it becomes significant. If unsure, use "Foot" rather than "US Foot".
Basis of Bearing
North/South Degree Minute Second East/West	A Basis of Bearing is used instead of true north or magnetic north as the reference for the Courses. It follows the same rules as Direction (See Above). If there is no Basis of Bearing, leave these fields blank.
