• Calculating GSD: You can calculate GSD using online calculators or by using the following formula:

  GSD = (Flight Altitude * Sensor Width) / (Focal Length * Image Width)

  Where:

  • Flight Altitude is the altitude of the drone above the ground.
  • Sensor Width is the width of the camera sensor in millimeters.
  • Focal Length is the focal length of the lens in millimeters.
  • Image Width is the width of the image in pixels.

• Choosing the Right GSD: Choose the GSD that is appropriate for your mapping application. For example, high-precision surveys require lower GSDs than general-purpose mapping projects.

22. Mastering Georeferencing for Accurate Mapping

Georeferencing is the process of assigning real-world coordinates to aerial imagery. Accurate georeferencing is essential for creating maps that can be used for measurement, analysis, and integration with other geospatial data. Here are key aspects of mastering georeferencing:
