How do you read degrees on a survey map?
Degrees, minutes, and seconds are the units of measure for property survey bearings. For example, N 38° 03′ 09″ E would translate as 38 degrees, 3 minutes, 9 seconds from the north to the east. The boundary lines, or “legs,” are often denoted in feet and listed directly below or after the bearing.
How do you read a property map?
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.
What do Survey maps show?
This type of map shows the landscape features of an area, from hills and mountains to lakes and streams. They’re typically structured in such a way that the lines and shading indicate changes in elevation, which is useful if you’re assessing uneven or hilly land.
How do you read a land survey bearing?

How accurate is GIS Mapping?
What is the accuracy of the parcel data? The accuracy of the property lines varies depending on different factors. In general the newer a subdivision, the more accurate the mapped lines. In a newer subdivision, past 5 years or so, the lines are probably within 5 feet +/- of where they actually exist.
What is topo plan?
Topographical plans and maps are drawings which show the main physical features on the ground, such as buildings, fences, roads, rivers, lakes and forests, as well as the changes in elevation between land forms such as valleys and hills (called vertical relief).
How do you read bearings?
The bearing of a point is the number of degrees in the angle measured in a clockwise direction from the north line to the line joining the centre of the compass with the point. A bearing is used to represent the direction of one point relative to another point. For example, the bearing of A from B is 065º.
Are bearings on survey maps magnetic or true north?

What does Ch mean on a plot map?

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 survey map with a compass?
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.
