5.6. Data Processing and Coordinate Systems

Try these first

1. 1.

   What is raw data in surveying?

   Hint

   Think about what instruments typically measure.

2. 2.

   Name one common coordinate system used in surveying?

   Hint

   Consider the systems for geographic referencing.

3. 3.

   What is the purpose of raw data processing in surveying?

   • To measure heights only
   • To convert raw data into geographic coordinates
   • To determine distances only

   Hint

   Consider what happens to data after collection.

4. 4.

   True or False: A datum serves as a reference point for measuring data.

   • True
   • False

   Hint

   Think about what guides measurement efforts.

5. 5.

   You have collected GPS data using WGS 84 but need to provide results in a local state plane coordinate system. Explain the steps and tools you would use for conversion.

   Hint

   What tools do you know can help with coordinate conversion?

6. 6.

   In a project using both Total Station and GPS data, describe how you would ensure accuracy when merging data collected from different systems.

   Hint

   What is crucial before merging datasets?
