What is considered good spatial resolution?

Typical spatial resolution in images acquired with clinical scanners is around 6–7 mm.

How is spatial resolution measured?

The size of the area viewed is determined by multiplying the IFOV by the distance from the ground to the sensor (C). This area on the ground is called the resolution cell and determines a sensor's maximum spatial resolution.

What determines high spatial resolution?

In terms of digital images, spatial resolution refers to the number of pixels utilized in construction of the image. Images having higher spatial resolution are composed with a greater number of pixels than those of lower spatial resolution.

What is a high spatial resolution?

Spatial resolution is the detail in pixels of an image. High spatial resolution means more detail and a smaller grid cell size. Whereas, lower spatial resolution means less detail and larger pixel size. Typically, drones capture images with one of the highest spatial resolutions.
