What do surveyors do? - Answer-take and analyze measurements
What do surveyors measure? - Answer-measure distance, angles, and positions
How do plane surveys and geodetic surveys differ? - Answer-Plane surveying: the
surface of the earth is considered as plane and the curvature of the earth is neglected.
Most of engineering and property surveys are considered plane surveys.
Geodetic surveys: the curvature of the earth is considered. Geodetic surveys used for
traditional surveys like national boundaries control network, modern surveys like data
gathering.. using satellite positioning techniques.
How is a total station different from an electronic theodolite? - Answer-Electronic
theodolite: is used to measure the horizontal and vertical angles with high precision.
Total station: is the combination of electronic distance measurement (EDM) and
electronic theodolite. Measure horizontal angels, vertical angles,
horizontal/vertical/slope distances. This gives more accurate results and reduces times.
Why is that surveyors must measure or determine the horizontal distances, rather than
just the slope distances, when showing the relative locations of two points. - Answer-
The surveyor measures the horizontal distance to plot the plan or for design purpose
rather than measuring slope distance.
If the slope distanced is measured, it is converted to horizontal distance by taking the
difference in elevations or slope angles by using the trigonometric relations. Vertical
distance is measures with the help of tape in the construction site.
What is the difference between adverse possession and free simple - Answer-Adverse
possession is known as a legal method of taking property that another person is
occupying. This hostile act is defined on a state by state basis. Possession must be
acquired in statutory period while the adverse climated must be notified with a burden of
proof. While fee simple is known to be more interest in land. Land owned within fee
simple has no limitations or conditions, thought its owned.
What is a metes and bounds legal description. Is it typically used for simultaneous
conveyances such as a lot of in a city tract. - Answer-Metes and Bounds
Metes indicates direction and distance
Bounds indicates some controlling Boundary
, Metes and bounds are nothing but the limits or boundaries of a piece of property as
identified by its natural landmarks. Such as lakes, rivers, or manmade markers. It is
typically used for simultaneous conveyances.
What is the difference between Riparian and Littoral Rights? - Answer-Riparian rights
pertain to pertain to the land owners whose property is adjacent to a lake, river, or
stream. Those who property borders this surface water has the right to use the water
that is on their land.
Littoral rights pertain tot hose who own land bordering an ocean or lake, they
unrestricted rights to the water.
What is the difference between a point of beginning and point of commencement -
Answer-Point of commencement (POC) is the point of the property to be inspected
begins.
Point of beginning (POB) the point where the location of the starting point to be
inspected begins.
Why is it that sometimes chord and arc lengths for the same curve interval appeal to be
equal in value? - Answer-In situations like flat curves and short distances, it appears
that chord and arc are equal. But, when calculating the first and last sub chords, if more
decimal places are introduced into the calculation, the difference between arc and chord
can be seen.
Measurement and calculation mistakes are to be avoided in all forms of surveying. Why
is it that construction surveyors need to be even more vigilant about recognizing and
correcting mistakes. - Answer-Calculations mistakes and measurements mistakes are
being avoided in all forms of surveying. However construction surveyors needs to be
even more vigilant about recognizing and correcting mistakes because after the contract
is awarded the contractors start working immediately due to having certain
commitments with employees and equipment. The responsibilities are more and the
working conditions are less. In order to complete the project perfectly without any
drawbacks more concentration must be taken in correction of mistakes. At the initial
stage itself precision must be take to avoid overlook regarding the measurements and
calculation part.
Difference in height - Answer-zenith angle (always cosine)
Difference in level - Answer-zenith angle (always sin)
Datum - Answer-a level surface taken as a surface of reference
Elevation - Answer-the vertical distance from the datum
