Sensor Independent Derived Data

	Sensor Independent Derived Data


	Overview:

	The suite of Sensor Independent Derived Data (SIDD) standardization documents describe the implementation of various data products generated by Synthetic Aperture Radar (SAR) systems and their data processing elements. SAR-derived image products, and their associated metadata, are grouped around common tasks for downstream users. The SIDD documentation provides specifications for these common tasks which are designed to support basic exploitation, geographic measurements, and proper visual display. Additionally, the documentation specifies the SIDD supported coordinate systems and product image pixel arrays. The real utility of SAR image collection is in the products and measurements that may be derived from it. The quality of the pixel array data along with the set of metadata provided are critical in generating the derived products. The “sensor independence” of the SIDD product refers to the ability of the allowed pixel array and metadata options to accurately describe the image products from sensors and data processing systems. Sensor independence does NOT mean that all products have the same format for the pixel array or the same set of metadata parameters.To Download the sample files, right click on the link and select 'Save Target As'.
