Procedures

These pages document established procedures for processing, data delivery, archiving, etc. Please be aware that these pages may be written in technical language as they are mainly used for documenting internal processing.

Project processing procedure

This page contains links to detailed step-by-step instructions on how to deal with data from arrival to dispatch to the user. Please keep updated. A simplified overview of the procedures can be seen in the flow chart. Clicking on the relevant section will give a more detailed, technical description.
