1.22.1. Trilateration

Try these first

1. 1.

   What is trilateration?

   Hint

   Focus on how distances relate to determining locations.

2. 2.

   Name one application of trilateration.

   Hint

   Think about where accurate location is necessary in cities.

3. 3.

   What key technique does trilateration primarily rely upon?

   • Measuring Angles
   • Measuring Distances
   • Estimating Coordinates

   Hint

   Think about what it means to measure distances.

4. 4.

   True or False: Trilateration is less accurate than triangulation.

   • True
   • False

   Hint

   Recall the benefits of using technology in surveying.

5. 5.

   A surveying team needs to establish a new point using trilateration. They have three control points measured at distances of 100m, 150m, and 200m. Calculate the approximate position of the new point based on these distances.

   Hint

   Visualize this scenario with a drawing—a diagram can help understand how the circles intersect.

6. 6.

   Explain the role of EDM technology in improving the accuracy of trilateration in a surveying project aimed at urban development.

   Hint

   Consider the challenges of measuring in crowded cities and how technology can alleviate those issues.
