NONE
Step-by-step solution
1. Surveying types are categorized based on the specific features and terrain information being mapped. 2. Topographical surveying measures and depicts physical terrain features, both natural and artificial. 3. Features such as rivers, valleys, lakes, hills, and contours are mapped using topographical surveys. Answer: D
Explanation
Topographical surveying is conducted to map both natural physical features like rivers, mountains, and valleys, as well as artificial man-made features. It records relative positions and elevations to represent the terrain accurately on maps. In contrast, cadastral surveys deal with legal property boundaries and city surveys deal with urban infrastructure.
Why the other options are wrong
A) City surveying is utilized for urban planning, streets, and municipal service lines. B) Location surveying is used for setting out engineering works on the ground. C) Cadastral surveying is conducted to determine legal property boundaries and land ownership.
Shortcut
Topographical survey = Natural features (valleys, rivers, lakes).
Common mistake
Confusing topographical surveying with cadastral surveying, which is used for legal property boundaries.
Correct answer: D) Topographical surveying
