How Do You Read a Bearing on a Survey
To read a bearing on a survey, first find the starting point and the ending point. Then, use a compass to find the angle between the two points. The bearing will be the number on the compass that is directly opposite of the angle.
In order to take a bearing on a survey, you’ll need to first identify two objects that are in line with each other. Once you have those objects identified, you’ll align your compass so that the needle is pointing at one of the objects. From there, you’ll rotate your body until the other object is in line with the rear sight on the compass.
At that point, you’ll read the bearing on the dial of the compass.
How to Read Survey Measurements
Whether you’re a professional surveyor or simply need to take some measurements for a home improvement project, understanding how to read survey measurements is essential. Here’s a quick guide to help you make sense of those numbers:
The first thing to know is that all surveys are based on a horizontal plane, which means that the measurement will be taken from side to side, rather than up and down.
This is important to keep in mind when reading the numbers.
Next, you’ll see a number followed by the letter “B”. This stands for “base line”, and it’s the starting point for all of the other measurements.
The base line is usually established by two points that have already been surveyed.
From there, you’ll see a series of numbers with either an “L” or an “R” next to them. These stand for “left” and “right”, and they indicate which direction the measurement was taken from the base line.
So, if you see an L next to a number, that means the measurement was taken from the left side of the base line; if you see an R next to a number, that means it was taken from the right side.
Finally, you may also see some numbers with no letters next to them. These are called offsets, and they’re used when taking measurements from objects that can’t be directly surveyed (like buildings or trees).
To find out where these offsets are located, simply look at the previous measurement – whichever side it was taken from will be where the offset is located.
With this quick guide in hand, reading survey measurements should be a breeze!
Survey Bearings Explained
Survey bearings are an important tool for surveyors, but they can be confusing to those who are not familiar with them. In this blog post, we will explain what survey bearings are and how they are used.
A bearing is simply the direction from one point to another, measured in degrees clockwise from north.
For example, a bearing of 45 degrees would be northeast. Bearings can be relative or absolute. Relative bearings are based on a starting point, while absolute bearings use true north as the starting point.
Surveyors use both types of bearings when taking measurements. Relative bearings are typically used when measuring property boundaries or other features that do not have a known starting point. Absolute bearings are used when measuring distance or azimuths (the angle between two lines).
Surveyors usually take measurements with a compass or GPS receiver, which will give them the necessary information to calculate bearings accurately.
Bearings can be further classified as either horizontal or vertical. Horizontal bear- ings measure the direction between two points on the same plane (elevation), while verticalbearings measure the direction between two points that are not on the same plane (elevation difference).
Vertical angles are always measured from horizontal planes and expressed in terms of percent grade (%G) instead of degrees like horizontal angles. For example, a vertical angle of 30%G would mean that for every 100 feet horizontally, there is 30 feet of elevation change vertically – meaning the slope is very steep!
Convert Survey Bearings to Degrees
If you’re working with a map and compass, it’s likely that you’ll need to convert survey bearings to degrees at some point. Here’s how to do it:
First, identify the bearing that you want to convert.
Let’s say it’s N 45° E.
To convert this bearing to degrees, simply subtract the number before the ° symbol from 360°. In this case, that would give you 315°.
That’s all there is to it! Just remember that when working with bearings, the degree symbol (°) always goes after the number, not before like usual.
How to Read a Land Survey Elevations
If you’re looking to develop a piece of property, it’s important to be able to read a land survey elevation. This will give you an idea of the topography of the land and any potential obstacles you may encounter during development. Here’s how to read a land survey elevation:
The first thing you’ll want to do is find the datum point, which is typically marked with an “X.” This is the starting point for all measurements on the survey. From there, you’ll take note of the contour lines, which show changes in elevation.
The closer together the contour lines are, the steeper the slope; conversely, if they’re further apart, it indicates a gentler slope.
Next, pay attention to any spot elevations that are noted on the survey. These will be specific points on the property where the elevation has been measured.
You can use these spot elevations to get an idea of how much vertical change there is between different points on the property.
Finally, take a look at any benchmark elevations that are listed. A benchmark is a permanent marker that has been placed by a government agency in order to provide an accurate reference point for elevation measurements.
By comparing your property’s elevations to those listed on the benchmark, you can get a more accurate sense of its topography.
How to Read a Survey Plat Map
A survey plat map is a document that shows the legal boundaries of a piece of land. It is used by surveyors, engineers, and others who need to know the property lines of a given area. The plat map is usually drawn to scale, meaning that each inch on the map represents a certain number of feet in real life.
This makes it possible to use the map to measure distances between points on the property.
To read a survey plat map, start by finding the title block, which includes information such as the name of the surveyed property, the date of the survey, and the scale of the map. Then, locate the north arrow, which will help you orient yourself on the page.
Next, identify any landmarks that are shown on the map, such as buildings or bodies of water. Finally, use your ruler or measuring tape to determine distances between different points on the property lines.

How Do You Read Land Survey Symbols?
There are a few different types of land survey symbols, and each one has a different meaning. The most common type of symbol is the lot line, which indicates the boundary between two pieces of property. Other common symbols include eamanly cheesets, rights-of-way, and boundaries.
Each type of symbol has its own specific meaning, so it’s important to know what you’re looking at before you begin reading a land survey.
Lot lines are usually indicated by a solid line with arrows at either end. These arrows show the direction in which the line runs.
If there is more than one lot line on a survey, they will be labeled with letters or numbers so that you can tell them apart. Eamanly cheesets are indicated by dashed lines, and typically run through someone’s property to allow access to another person’s property. Rights-of-way are similar to eamanly cheesets, but they’re typically used for utilities like waterlines or powerlines.
Finally, boundaries are indicated by dotted lines, and these mark the edge of a piece of property.
Now that you know what the different types of symbols mean, let’s take a look at how to read them. To start, find the starting point of the survey (this is typically marked with an X).
From there, follow along the lines until you reach the next symbol. The easiest way to do this is to trace your finger along the line as you read. Once you reach the next symbol, identify what type it is and what it means in relation to the rest of the survey.
Continue following along until you reach the end of the survey (which is usually marked with an X).
By following these steps, you should be able to easily read any land survey symbols that you come across!
What is Survey Basis Bearing?
Survey basis bearing is a term used in surveying that refers to the horizontal angle between two lines of sight. The first line of sight is from the surveyor to the point being surveyed, and the second line of sight is from the surveyor to a known point (usually a reference point on the ground). The survey basis bearing can be used to determine the direction of travel for a particular route, or to calculate distances between two points.
How Do You Read Survey Directions?
When taking a survey, it is important to read the directions carefully in order to accurately answer the questions. The first step is to identify the question type. There are four main types of questions: multiple choice, rating scale, open-ended, and demographic.
Multiple choice questions have a list of possible answers to choose from. Rating scale questions ask you to rate something on a scale, usually from 1-5 or 1-10. Open-ended questions require you to write a response in your own words.
Demographic questions ask for information about yourself, such as your age or gender.
Once you know what type of question you are answering, follow the instructions carefully. For multiple choice and rating scale questions, simply choose the answer that best applies to you or rates the statement accordingly.
For open-ended questions, take your time to thoughtfully craft a response that answers the question completely. And for demographic questions, simply provide truthful information about yourself.
By taking the time to read and understand the survey directions before starting, you can be sure that you are providing accurate responses that will be helpful in research or decision making!
How Do You Read Lot Dimensions?
When reading lot dimensions, the first thing you need to do is identify the property boundaries. This can be done by looking for markers like fences, trees, or rocks that indicate where the property line is. Once you have found the property boundaries, you can then start measuring the lot.
To measure the lot, you will need to take into account the width and depth of the property. The width of a lot is measured from one side of the boundary to the other. The depth of a lot is measured from the front of the boundary to the back.
To get an accurate measurement, it is best to use a tape measure.
Once you have measured the width and depth of the property, you can then calculate the square footage of the lot. To do this, you will need to multiply the width bythe depth.
For example, if a lot has a width of 50 feet and a depth of 100 feet, its square footage would be 5,000 square feet (50 x 100).

Conclusion
In order to read a bearing on a survey, you will first need to find the station point. The station point is usually indicated by an X on the map. Once you have found the station point, draw a line from the X to the object that you are trying to find the bearing for.
To determine the bearing, you will need to use a protractor. Place the center of the protractor on the X and align one side of the protractor with the line that you drew from the X to the object. The number that lines up with the other side of the protractor is yourbearing.
