What is the similarity between plane surveying and geodetic surveying?

in plane survey the surface of earth assume as plane or straight its uses as limited distance where as in geodetic survey surface of earth assume as curve its use in long distance.


What are the methods and techniques used by scientists to probe the interior of the Earth?

Scientists use methods like seismic imaging, gravity mapping, magnetotellurics, and geodetic measurements to probe the Earth's interior. Seismic imaging uses seismic waves to create images of the Earth's interior based on how they propagate through different materials. Gravity mapping measures variations in the Earth's gravity field to infer density differences and structure beneath the surface. Magnetotellurics measures electromagnetic fields to study the Earth's electrical conductivity, revealing information about its composition and temperature. Geodetic measurements monitor changes in the Earth's shape and rotation, providing insights into internal processes.

Why do you use significant digits when dealing with measurements?

Measurements need to be specific so we use significant digits.

How to transformation geodetic to geocentric coordinates?

To transform geodetic coordinates (latitude, longitude, height) to geocentric coordinates (x, y, z), you can use appropriate mathematical formulas or libraries. One common approach is to use the WGS84 ellipsoid model and apply the conversion formulas that account for the Earth's shape when transforming coordinates. Various software tools and programming libraries are available to perform this conversion accurately.


What unit of measurements would you use to go to estapona to malaga?

You would not use measurements but a form of transport! To measure the distance, you would use kilometres.


What term do astronomers use for the time it takes for a planet to orbit the sun relative to the stars?

Astronomers use the term "sidereal period" to describe the time it takes for a planet to orbit the sun relative to the stars. Sidereal periods are measured based on the apparent motion of a planet against the background of fixed stars rather than against the sun. This allows for more precise measurements of a planet's orbital period.


What is the system of measurements that scientists use?

They use the Metric system.


How are measurements used in construction?

The construction field use scales as measurements for the exact calculation of distance and deepness in every materials. The measurements are use to create a well calibrate construction who will stand the test of time.

When was the mile first established?

The North American Datum of 1983 (NAD83), which is defined in metres, replaced The NAD27 in the 1980s. The State Plane Coordinate Systems were also updated, but the National Geodetic Survey left the individual states to decide which (if any) definition of the foot they would use. All State Plane Coordinate Systems are defined in meters, and 42 of the 50 states use the meter-based State Plane Coordinate Systems only.
