How do you read compass bearings on a survey map?
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 directions on a survey map?
Each segment will contain numbers and letters indicating the direction from North that the line proceeds as well as the distance to the next point. For example, a segment may have the notation N 15° 30′ 45″ E on one side of the line and the notation 166.25′ on the other side of the line.
How do you read Land Survey symbols?
Understand the property boundaries.
- The bearing represents the angle between north or south and east or west. …
- Degrees, minutes, and seconds are the units of measure for property survey bearings. …
- The boundary lines, or "legs," are often denoted in feet and listed directly below or after the bearing.
Are surveys true north or magnetic north?
Surveyors used a compass to determine the direction of survey lines. Compasses point to magnetic north, rather than true north. This declination error is measured in degrees, and can range from a few degrees to ten degrees or more.
What are the coordinates on a survey?
Coordinates are used for describing the exact position of a location on the ground, or on a map or plan. They normally take the form of figures that indicate the distance of the location concerned from the two coordinate axes.
How do you read survey elevations?
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. That number is your true elevation.
What do colored survey markers mean?
Pink is strictly used by land surveying companies to state where the temporary survey markings are. The color codes for locating utilities, conduit or rebar in concrete can present slightly different colors depending on the surface. Most often used are the colors red, yellow, blue and black.
Where is the north arrow located on the survey?
The north arrow or north point must be shown on all survey plans as it shows the relationship between the subject lands to the official north direction. Typically, the north arrow is positioned visibly at the top of the survey plan.
Do surveyors use magnetic north?
Surveyors used a compass to determine the direction of survey lines. Compasses point to magnetic north, rather than true north. This declination error is measured in degrees, and can range from a few degrees to ten degrees or more.
How do I find the latitude and longitude of a survey map?
From an Android device:
- Open the Google Maps app.
- Zoom in to your property's location.
- Tap and press your property's location until a red pin appears. (It must be a point that isn't already labeled).
- The GPS coordinates will appear in the search box at the top of the map.

What do pink markers mean on property?
Pink is strictly used by land surveying companies to state where the temporary survey markings are. The color codes for locating utilities, conduit or rebar in concrete can present slightly different colors depending on the surface.
Does the north arrow always point up on a map?
Not always. The compass pointing to North and South. It would be practical to position the map along with the compass.
Do Survey maps use true north or magnetic north?
Surveyors used a compass to determine the direction of survey lines. Compasses point to magnetic north, rather than true north. This declination error is measured in degrees, and can range from a few degrees to ten degrees or more.
What compass do surveyors use?
A circumferentor, or surveyor's compass, is an instrument used in surveying to measure horizontal angles. It was superseded by the theodolite in the early 19th century.
Do surveys show true north or magnetic north?
Surveyors used a compass to determine the direction of survey lines. Compasses point to magnetic north, rather than true north. This declination error is measured in degrees, and can range from a few degrees to ten degrees or more.
What do the coordinates mean on a survey?
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.
Do Surveyors use GPS coordinates?
Not only is it used by land surveyors, trilateration is also used to determine location coordinates with Global Positioning System satellites and receivers.
How do you read a contour survey?
Widely spaced contour lines indicate gentle slope. Equally spaced contour lines indicate uniform slope. Closed contour lines with higher elevation towards the centre indicate hills. Closed contour lines with reducing levels towards the centre indicate pond or other depression.
What do the numbers on the map represent?
These numbers represent two grid systems that can be used to find your exact location. The first is called latitude and longitude. The exact latitude and longitude is given at each corner of that map and at equally spaced intervals between the corners. The second is called UTM's.
What do little white flags in a yard mean?
excavation It signifies electric utilities, such as cables and power lines. These mark the power lines that connect to a neighbor's power grid. Marking these junctions helps avoid a neighborhood-wide power outage. White flags – White flags mean excavation. Often you'll see these set out for a city excavation project.
Where should north arrow go on map?
By convention north is towards the top of the page (thus some maps do not have north arrows), but the orientation must still be given for a 'proper' map. North does not have to be at the top of the page and a north arrow is essential in maps where it is not. 4.
How far off true north is magnetic north?
The Geographic North Pole is static and is located about 1200 miles north of the Magnetic Pole. Maps and directions are usually oriented toward the Geographic Pole, also referred to as "True North."
Which method is more accurate in plotting a compass survey?
ADVERTISEMENTS: If the length and bearing of a line are known, its projection on the y-axis and x-axis may be calculated and then plotted. This method is the most accurate of all the methods of plotting because the use of protractor is entirely done away and each point is plotted independent of the others.
How many types of compass are used in surveying?
two There are two main kinds of magnetic compass used in surveying, both of which are included in the collection – the Surveyor's compass and the Prismatic compass. The surveyor's compass is usually the larger and more accurate instrument, and is generally used on a stand or tripod.
