NDVI Calculation for Clipped Areas

When a customer orders imagery through the Orders API with a clip operation and an NDVI calculation (typically as a 5th band), the calculation is applied only to the pixels within the clipped Area of Interest (AOI).

How it Works

While the process technically targets the clipped area, it is important to understand the underlying logic:

  • Pixel Independence: The bandmath operation functions on a per-pixel basis. This means the value of one pixel does not depend on its neighbors.

  • Consistency: Because each pixel is calculated independently, the resulting NDVI value for a specific coordinate will be identical whether it is calculated as part of a small clip or a full-sized scene.

  • Efficiency: Processing only the clipped area reduces compute time and file size, ensuring you only receive the data relevant to your specific AOI.
