How do you read a survey map coordinates?
Directly to your right (East) would be 90 degrees East of North. If you turned around you would be facing South and would be 180 degrees South of North. As you continue to turn you would face West, located 90 degrees West of North. Survey plats can also be read in reverse.
How do you read a plat of survey?
Plat maps list the house number for each parcel, along with the shape of the parcel, or the parcel boundary. The small numbers along the bottom of the parcel is the width, and the number along the right side of the parcel is the depth. Most plat maps have these numbers in feet.
How do you read a survey bearing?
A direction that is expressed as a standard bearing is also based on a 360 degree circle but uses different points of reference. A bearing of N 60 degrees east means the direction is 60 degrees to the east of north. Likewise a bearing of S 15 degrees east means the direction is 15 degrees to the east of due south.
How do you read a land location?
The legal description of land follows a set sequence of quarter section, township, range, and meridian: the designation NW 27-9-25 W2, for instance, means the Northwest Quarter of Section 27 in Township 9 Range 25 West of the Second Meridian.
What do the coordinates on a survey mean?
In photogrammetry, space coordinates are also called “survey coordinates,” and are the x-coordinates and y-coordinates which define the horizontal position of a point on a ground system, and the z-coordinate, which is the elevation of the point with reference to the ground system.
What does B l mean on a survey?
BSL – Building Setback Line.
How do you read survey elevations?
Run the detector and / or front rod section up or down until you pick up the “on grade” signal from your detector. Read the number opposite the pointer. That number is your true elevation. If using an optical instrument, just read the number across the horizontal line.
How do you read a section map?

Read the Compass Degree system by starting with a specific point on the compass (north, east, south or west), and then reading the number of the degrees to the next point on the compass. An example heading might be N63E.
Are bearings on survey maps magnetic or true north?
Bearing: See Azimuth. Bearings taken with a compass will be referenced to magnetic north unless otherwise noted. Benchmark: A survey mark made on a monument having a known location and elevation, serving as a reference point for surveying.
How do you read a metes and bounds?
A metes and bounds description, which means distance and direction, begins and ends at a landmark called the point of beginning (POB). The property is measured and described in a point of direction from a starting point using angles, distance, directions, and landmarks.
How do you read a township and range map?
The boundary lines that run east-to-west, dividing North from South are called township lines. The boundary lines running north to side and divide East from West are called range lines. The township and range coordinates of adjacent townships depend upon the context of the existing township and range lines.
How do you read township and range description?
Sections in each township are numbered consecutively beginning with number 1 in the northeast corner of the township, and counting right to left then left to right and so on weaving back and forth through the sections of the township, and ending with number 36 in the southeast corner.
How do I see land location on Google Maps?
Go to maps.google.com. 2. Type out the coordinates into the search bar — using either the degrees, minutes, and seconds (DMS) format, the degrees and decimal minutes (DMM) format, or decimal degrees (DD) format — then hit enter or click on the search icon.
What does Pol mean in surveying?
In earlier times, under regulations found in various manuals of surveying instructions, surveyors were to set a Point on Line (POL) on top of ridges or spurs, at places where the line crossed trails or roads and at other like places. This was done to facilitate identification of the line.
