Heterogeneous Missions Accessibility(HMA)
Introduction and Objectives
The Ground Segment Coordination Body GSCB started to address
this challenge in 2005 through the HMA (Heterogeneous Missions
Accessibility), a collaborative project among the European and Canadian
Space Agencies and lead by the European Space Agency, which
objective is to guarantee a seamless and harmonised access to heterogeneous
earth observation (EO) datasets from multiple mission
ground segments, including national missions and ESA missions.
The goal of HMA is to define the interoperability concept, standardise
the ground segment interfaces of the satellite missions for easier
access to EO data. Thus HMA provides interoperability for coordinated
data access enabling the interactions with services or Value
Adders and EO Contributing Missions.
HMA focuses therefore in the definition of the interfaces among the
Users of space observation data and the different ground segments
(and among the ground segments) in a well specified end to end architecture.
HMA has defined the discovery, catalogue ordering feasibility
analysis and identity management interface standards relying
on existing standards, if available,
and the direct collaboration
among the space agencies.
has followed at the maximum extent
already available international
standards and coordinated with
the EC INSPIRE.
