The first piece of information you need to determine elevation is the reference point or datum. This serves as the starting point for measuring height above or below a specific level, such as sea level or ground level.

A spot elevation of 1237 feet is shown on a topographic map If the contour interval of themap is 20 feet what is the value of the first contour line below the spot elevation?

The first contour line below the spot elevation of 1237 feet would be at 1220 feet (1237 feet - 20 feet = 1217 feet).


What was the first culture to determine earth was a sphere?

The ancient Greeks were the first culture to determine that the Earth was a sphere. Philosophers such as Pythagoras and Aristotle provided evidence through observations and reasoning that supported this belief.


What data do you need to make a topographic map?

Topographic maps are specifically purposed for elevation of the land area, as well as outlining geographic locations, such as mountains. Topographic maps are used by architects, geographic profressionals, and by outdoor recreations, primarily hikers.Difficulty: Moderately EasyInstructions1 Determine the location you want to map, and gather maps of that location from local libraries or Internet resources, such as the link in the Resources section. From the maps you have aqcuired, record elevation levels, compass, scale, and any landmarks.2 Establish a scale, which will represent the distance. For example, one inch represents one mile. Draw the scale on a corner of the map.3 Create a compass direction, the four arrows that designate North, East, South, and West, from which you will establish how the map will face. The compass is typically located on the corner of the poster.4 Draw the general shape of the location you are mapping, starting with the lowest elevation first. Label that line with whatever elevation it may be.5 Start drawing elevation lines based on an established increment; for example, draw a line for every 50 feet of elevation.6 Create symbols for significant landmarks, such as a triangle shape to symbolize a mountain peak.7 Write the location of the map at the top of the poster.Tips & WarningsUsing as many maps available to create the topographic map will give more accurate detail, such as elevation levels, specific landmarks, etc.


What is the elevation when you are at sea level?

The simple answer is zero feet elevation, but first of all, it is almost impossible to tell that you are at the exact sea level that is the average of all the different sea levels caused by all the different tide elevations. That is why GPS and surveying do not much use "mean sea level", anymore. These days "zero elevation" is determined by the strength of the field of gravity as calculated and measured all around the world.


Compute the boiling point elevation of a salt water solution that contains 3.40 g of NaCl dissolved in 148 ml of water?

The boiling point elevation of a solution can be calculated using the formula: ΔTb = i * Kf * m, where i is the van't Hoff factor, Kf is the cryoscopic constant for water (0.52 °C kg/mol), and m is the molality of the solution. First, calculate the molality of the NaCl solution using the given mass of NaCl and the molecular weight of NaCl to find the molality. Then, use this molality value in the formula along with the van't Hoff factor for NaCl in water (i = 2) to determine the boiling point elevation.

How To determine the elevation by single plane method?

first we should select a position of the theodolite and initial adjustments are to be carried out then take back sight from the BM and then focus on the top of the object which we determine the elevation and take the vertical angle in bothvernier scales. after that take back sight to line of orientation to a known distance and locate a second point. then shift the instrument to the second point do all adjustments and take back sight to the BM and then focus on the top of the object take the vertical angle in bothvernier scales. after that using trigonometrical formula we calculate the elevation of the object.


How to determine the dip of formation from the geological map?

To determine the dip of formation from a geological map, first identify the strike direction of the rock layers, which is indicated by the orientation of the geological symbols. Next, look for contour lines or symbols that represent the elevation of the formations; the difference in elevation across a horizontal distance indicates the dip. Finally, use the formula for calculating dip, which involves the change in elevation divided by the horizontal distance, typically expressed in degrees. Additionally, any cross-sections included in the map can provide further insight into the dip of the formations.


Can a GPS be used to find elevation of a point?

Yes, some GPS devices have the capability to provide elevation information of a specific point. This feature may require a device with a barometric altimeter or access to elevation data from satellites or maps.


What are the steps to be followed to make a super-elevation?

To create a super-elevation in road design, follow these steps: first, determine the appropriate degree of super-elevation based on the road's design speed and curve radius. Next, calculate the required cross-slope by using the formula that considers speed, radius, and gravitational forces. Then, design the road cross-section to incorporate the super-elevation, ensuring proper drainage. Finally, implement the construction, ensuring that the transition into the super-elevated section is smooth for vehicles.
