Aerial imaging is a powerful tool that can be used to capture detailed views of the Earth from above. There are two main types of aerial imaging: nadir and oblique.

Nadir Imagery

Nadir images are taken with the camera pointed directly down at the ground. This provides a top-down view of the landscape, which is ideal for measuring elevation and creating accurate 3D models.

Nadir imagery is often used in applications such as:

  • Mapping
  • Orthophoto production
  • 3D modeling
  • Height measurement
  • Construction inspection

Oblique Imagery

Oblique images are taken with the camera pointing at an angle to the ground. This provides a wider view of the landscape, which can be useful for identifying features and objects that would be obscured in a nadir image.

Oblique imagery is often used in applications such as:

  • Architectural design
  • Urban planning
  • Land use analysis
  • Advertising

Conclusion

Nadir and oblique imagery are two different methods of aerial imaging that each have their own advantages and disadvantages. The best method for a particular application will depend on the specific needs of the user.
