Topographic surveys: determine locations of natural and artificial (buatan) features

Alignment surveys: plan and construct highways, railroads, etc

+ Land, boundary, cadastral surveys: establish property lines and boundaries

Question 4

Types of survey based on the computations

Answer 4

1. Geodetic surveying
   - curved surface of the earth
   - for distance > 10 km
   - > 180 degrees
   - plumb bob line intersecting at earth’s center
2. Plane surveying
   - flat horizontal surface
   - for distance <10 km
   - = 180 degrees
   - plum bob line parallel
