Land Survey is ...
The science of determining the relative position on horizontal plane.
The science of determining the relative position on a sphere.
The science of determining the relative position on the Earth’s surface.
The science of determining the distances on the Earth’s surface.
What's the different between Geodetic and Plane Survey?
Geodetic Survey doesn't take into account the true size, shape just the gravity fields of the Earth. Plane Survey assumes the Earth’s surface to be a plane.
Geodetic Survey takes into account the true size, shape and gravity fields of the Earth. Plane Survey assumes the Earth’s surface to be a plane.
Plane Survey assumes the Earth’s surface to be part of a sphere. Geodetic Survey takes into account the true size, shape and gravity fields of the Earth considering it flat.
Plane Survey assumes the Earth’s surface sometimes is flat. Geodetic Survey takes into account the size and shape of the Earth.

269⁰ 07′ 42″
269⁰ 70′ 42″
90⁰ 52′ 18″
90⁰ 52′ 81″
Calculate the values of Alpha (acute) and Beta
Alpha = 104⁰ 82′ 59″, Beta = 97⁰ 10′ 52″
Alpha = 104⁰ 28′ 06″, Beta = 97⁰ 01′ 29″
Alpha = 97⁰ 01′ 29″ , Beta = 104⁰ 28′ 06″
Alpha = 97⁰ 10′ 52″ , Beta = 104⁰ 82′ 59″
What's this formula? and
Why do we need it?
Standard error and SE is a measure of the mean of your data, that is, the precision of your measurement
Standard deviation and SD is a measure of the residuals of your data, that is, the precision of your measurement
Standard deviation and SD is a measure of the spread of your data, that is, the precision of your measurement
Weighted Mean and WM is a measure of the spread of your data, that is, the precision of your measurement
