Service Portfolio

The F-TEP service portfolio covers thematic processing services (Table 1) and supporting processing services (Table 2), as well as interactive applications (Table 3). A separate Service Portfolio document (pdf) gives a brief overview on the services, while the User Manual gives detailed guidance on how to use each service and tool.

In the tables below, services and tools that are listed as “Core Offering” are readily available to all platform users. The services listed as “by agreement” are also deployed on the platform, and they can be made available for use through a separate agreement. Interested users are encouraged to contact us for enquiries.
