Data Processing & Product Generation

To deliver hyperspectral imagery data products in a consistent, scalable, reliable, and timely manner Wyvern has built a cloud-based data processing pipeline that converts raw sensor data and platform ephemeris metadata into usable output imagery data products that are delivered to end-users. The data processing pipeline includes spectral band co-registration at a < 25% subpixel level to ensure the best possible spectral purity in each pixel thereby enabling robust spectral analysis of the HSI data products.

Wyvern's cloud-based data processing and imagery product generation pipeline

Furthermore, the data processing pipeline for Wyvern's hyperspectral imagery data products requires that a significant portion of any given image includes unobstructed land with heterogeneous features in order to perform the georeferencing step that enables the standard geolocation accuracy specification. Consequently, the designated geolocation accuracy specification CE90 performance is only provided for imaging collections over unobstructed land that generate imagery data products with < 20% cloud cover. For any imagery data products collected over open water or with higher levels of cloud cover Wyvern does not offer a designated geolocation accuracy specification. Instead, each HSI data product over open water, homogeneous features or high cloud cover will have a geolocation characteristic that is limited to the inherent pointing accuracy of the Dragonette satellites which varies by imaging collection in the approximate range of several kilometres.
