18.12.3.1. Data Correction

Try these first

1. 1.

   What does RTK stand for in surveying?

   Hint

   Think about the real-time aspect of the data.

2. 2.

   Does PPK involve real-time corrections?

   Hint

   Remember the 'post' in Post-Processed.

3. 3.

   What is a primary advantage of RTK?

   • Less expensive equipment
   • Real-time accuracy during flight
   • Post-processing time is quicker

   Hint

   Consider what 'real-time' means.

4. 4.

   PPK methodology requires constant communication.

   • True
   • False

   Hint

   Think about when the corrections are applied.

5. 5.

   Given a scenario where we need precise measurements for a construction site but the location is known for poor communication signals, which method would you recommend? Explain why by weighing the pros and cons of RTK versus PPK.

   Hint

   Consider each method’s requirements and capabilities.

6. 6.

   Analyze a situation where you must conduct a survey for a utility corridor in a densely populated urban area. Discuss the implications of using RTK versus PPK.

   Hint

   Think about how urbanization can impact signal transmission.
