The Product Definition Document (in the following PDD) provides detailed technical specifications for all of the product output layers of the new Global Food Monitoring (GFM) product of the Copernicus Emergency Management Service (CEMS). The PDD provides the reference information required to understand all elements of the various data processing chains, and explains the contents of the GFM product output layers, the main assumptions underlying their generation, and the limitations of the data.
Specifically, the PDD describes in detail the GFM products in terms of the physical and mathematical basis of the algorithms and systems for each step in the product generation. The PDD is organized as follows:
- Overview of data products, describes the eleven GFM product output layers and presents the overall product generation workflow.
- Satellite data pre-processing and ancillary data preparation, provides a detailed description of the pre-processing steps that are applied to the Sentinel-1 satellite data, as well as the preparation of all ancillary data.
- Generation of the GFM product output layers, presents the input and output data, and describes in detail the algorithms used for generating the eleven GFM product output layers.
- Product access and dissemination system for the GFM product
- Quality control of the GFM product
- Scientific references
- Glossary of mathematical symbols
