15.2.3. Base Mapping

Try these first

1. 1.

   What is base mapping?

   Hint

   Think about what base mapping is used for.

2. 2.

   Name one technology used in base mapping.

   Hint

   Consider advanced technologies in surveying.

3. 3.

   What technique uses laser light for measuring distances in base mapping?

   • Aerial Photogrammetry
   • LiDAR
   • GPS

   Hint

   Recall the name of the technology that uses light.

4. 4.

   True or False: Aerial photogrammetry can capture high-resolution images from the ground.

   • True
   • False

   Hint

   Think about how the images are obtained.

5. 5.

   A construction site requires mapping a forested area for a new highway. Discuss the best methods to use for base mapping, comparing both aerial photogrammetry and LiDAR techniques. Highlight their pros and cons.

   Hint

   Think about how both technologies can complement each other.

6. 6.

   An engineer notices discrepancies between base maps created using photogrammetry and LiDAR. Create a systematic approach to reconcile these differences.

   Hint

   Focus on integration and error checking as essential steps.
