Which one of the following types of equipment is used in topographic surveys and also for recording the shapes of buildings ?
- AElectromagnetic distance measurement devices
- BGPS
- CSatellite camera
- DAerial cameraCorrect
Solution
Concept
Use of the aerial camera
Step-by-step solution
1. The aerial camera records photographs from which topographic maps are made. 2. It is also used to record the shapes of buildings.
Explanation
Aerial cameras are the main equipment of photogrammetric mapping, capturing both terrain and structures.
Why the other options are wrong
EDM and GPS measure distances and positions; a satellite camera images large areas at low resolution.
Shortcut
Aerial camera → topography + buildings.
Correct answer: D) Aerial camera
