Answer 2

Surveying & Mapping is the technique, science & profession, of ascertaining the terrestrial/three-dimensional position of points & the distances & angles between them.

Explanation:

The aim of surveying is to make plans & maps to indicate different "objects on the ground" at their "relative position" to "suitable scale"

The main disciplines of surveying are:

• Land surveying.
• Mining surveying.
• Engineering surveying.
• Geodetic surveying.
• Hydrographic surveying.
• Hydrographic surveying.
• Photogrammetry and remote sensing.

Surveyors use equipment such as  robotic total stations, total stations,  retroreflectors, GPS receivers,  radios, 3D scanners, digital levels, handheld tablets,  drones, subsurface locators, GIS & other surveying software.
