3.2.2. EDMs classification based on range

Try these first

1. 1.

   What does EDM stand for?

   Hint

   Think about what measurement technology is.

2. 2.

   What is the range of a high-range EDM?

   Hint

   It's the longest range classification.

3. 3.

   What type of electromagnetic waves do high-range EDMs use?

   • Infrared
   • Microwave
   • Radio

   Hint

   It’s the wave type for the longest range.

4. 4.

   True or False: Medium-range EDMs can measure distances up to 50 km.

   • True
   • False

   Hint

   Review medium-range capabilities.

5. 5.

   Create a workflow for selecting an EDM based on a given surveying project that requires measurements over a mountain range. Justify your choice of EDM and the estimated range required.

   Hint

   Consider both the environmental conditions and project requirements.

6. 6.

   Analyze the implications of environmental conditions (like fog or rain) on different types of EDMs used in surveying.

   Hint

   Think about wave propagation and visibility in various conditions.
