What is the difference between NADIR Images and Oblique Images

It's all about perspective

NADIR Images

A NADIR image just means that the camera is facing directly beneath the camera/drone at the time of the exposure. 

Oblique Images

A Oblique Image is an image that is taken at an angle other than a NADIR angle. 

nadir and oblique

Avoid these situations

  • Too many NADIR images - You will not get any depth perspective about roof obstructions or structure facades with these images. These should only be used when flying large commercial structures.
  • Horizon Images - While capturing the horizon in images can create a very pretty picture, the horizon creates issues when trying to stitch images together, because there are little to no reference points. Delete these images prior to uploading into Scanifly if you accidentally captured any.
