An elevation survey is a type of land survey that measures the height of a specific point relative to a known reference point, typically sea level. This type of survey is commonly used in construction and engineering projects to determine the topography and elevation of the land.
What else can I help you with?
How do you read a construction survey stake?
To read a construction survey stake, look for markings that indicate measurements or alignment. Typically, these markings include distance to a reference point, grade elevation, and other relevant information for the construction project. Consult the project's survey plans and coordinate with the site surveyor if there are any uncertainties.
What is a long section survey in engineering survey?
A long section survey in engineering surveying is a graphical representation of a terrain profile along a specific linear path. It typically includes elevation data and features such as ground profiles, existing structures, and proposed works to aid in design and construction planning. Long section surveys are commonly used in civil engineering projects like road and railway design.
How do you spell the word survey?
The word is spelled "survey."
What is parcellary survey?
a survey
What is the plural of survey?
The plural of the noun survey is surveys.
Distance above or below sea level?
On a British Ordnance Survey map 'contour lines' indicate the height above sea level and a 'trig point' indicates the top of a mountain or other high point.
How can I learn how to read a topographic survey effectively?
To learn how to read a topographic survey effectively, you can start by understanding the key symbols and lines used in the survey. Familiarize yourself with contour lines, spot elevations, and other features on the map. Practice interpreting the elevation changes and landforms represented on the survey. Additionally, consider taking a course or workshop on topographic mapping to deepen your understanding.
How do you find out a town's elevation above sea level?
You can find a town's elevation above sea level by using online mapping tools like Google Maps or apps like topographic maps. You can also check government sources such as the US Geological Survey (USGS) or official town websites for elevation information.
Who are survey agencies in India?
Morsel (Mass Oriented Research and Social Elevation Lab) You can contact them care@morselindia.org I have worked with them in Bihar, Uttar Pradesh and Rajasthan
What is the elevation of los angeles with color?
You can download topographic maps of anyplace in the US from the US Geological Survey at www.usgs.gov (go to the Maps, Imagery, and Publications link).

How do you calculate subsidence rates?
survey the land or entire area with surveying equipment, look at previously recorded survey data from over the years, compare your findings with those previously taken, to see what the rate of subsidence is for the area.
How to accurately interpret and utilize land survey measurements?
To accurately interpret and utilize land survey measurements, it is important to understand the key components of a survey, such as boundary lines, property corners, and elevation changes. Utilize tools like maps, compasses, and GPS devices to accurately measure and record data. Consult with a professional surveyor for complex projects or legal disputes.
Who is responsible for making topographic maps of all states in the US?
The United States Geological Survey (USGS) is responsible for creating and maintaining topographic maps of all states in the US. These maps provide detailed information about the landscape, including elevation, trails, bodies of water, and land use.
How to calculate results on a land survey rod?
The question is a bit confusing in the way it is asked. Typically you use the rod to gain elevation (numbers) and then calculate the elevation of a certain geographical point using a basic survey technique known as leveling. Leveling combines the calculations of a known elevation, known as a bench mark (BM), to the height of a survey level (height of instrument). The process of leveling is done in what is called loops. There are two loops in the process an open loop, and a closing loop. To open the loop, the height of the instrument (HI) is calculated using the rod. A rod person stands with the rod placed on top of the BM and the surveyor uses the level to shoot what is known as a back sight (BS). The number read on the rod by the surveyor is added to the know elevation of the BM; this gives the HI. After the HI is established, the rod person moves to some point (preferably a solid object no greater than 50' away from the BM) and places the rod on this point; this point is called a turning point (TP). The surveyor now shoots what is known as a fore sight (FS). The new number read on the rod is subtracted from the HI and the elevation of the (TP) is established. Next, the surveyor moves the instrument to a new location while the rod person stays at the TP. A BS is shot at the TP and the HI is again established. This process of establishing TP elevations and moving the instrument is repeated until the geographical point in question is established; now the open loop is completed. Once the elevation has been established the open loop must be closed. This is done to ensure that no errors occurred on the part of the surveyor during the survey. To close the loop the whole process is done in reverse. The rod person remains at the established elevation while the surveyor moves or changes the height of the instrument. Then the whole process is redone working back towards the BM using the derived elevation and the established TPs. The loop is closed when the survey and rod person calculate the BM elevation based on the established elevation of the geographical point in question. The calculated BM elevation is subtracted from the known BM elevation to give the survey error. While this sounds complex, the process is quite simple and after a few tries can be a fun thing to do.
How do you calcuate height of instrument in surveying?
When surveying using a "level" instrument , the "level" instrument is set-up and adjusted to level by adjusting the screws. When surveying you have an instrument person and a rod person. When trying to find the height of the instrument, the rod person places there rod over a "known" elevation, either a benchmark or a temporary benchmark that has a known elevation. To get the height of the instrument, you need to "shoot" the level to the rod person holding the rod on the known elevation, this is called the "Backsight". This elevation will be read by the instrument person, and recorded in the survey field book. This value backsight elevation will then be added to the known elevation of the benchmark or the temporary benchmark, to get the height of instrument. HI = known elevation + BS Height
