Overview
Allow me to take you on a tour in the world of
• a set of coordinated, independent Earth observation, information and processing systems that interact and provide access to diverse information for a broad range of users in both public and private sectors.
• links these systems to strengthen the monitoring of the state of the Earth. It facilitates the sharing of environmental data and information collected from the large array of observing systems contributed by countries and organizations within GEO.
• ensures that these data are accessible, of identified quality and provenance, and interoperable to support the development of tools and the delivery of information services.
GEOSS increases our understanding of Earth Processes and enhances predictive capabilities that underpin sound decision-making: it provides
access to data, information and knowledge to a wide variety of users.

Shall be able to handle/serve:
• Heterogeneous data from different sensors, (satellites, airplanes, possibly drones,
in-situ), with different quality, different scales (global, regional, local, ..)
• Different providers, archives, …
• Voluminous data (e.g. sentinel data)
• Wide variety of users from data scientists to decision and policy makers, within the public and
private sector, and considers as well citizens as part of their target community – as well as users from
different application domains…
Shall offer
• GUI/front-end that is map-based
• Possibly data visualisation
• Single (generic) Internet access point

Map-based, single Internet access point/GUI providing generic as well
as more community-specific search capabilities supporting as well users
interested in particular societal benefits of application of Earth observations.

The GEO DAB brokering framework interconnects hundreds of heterogeneous and autonomous supply systems (the enterprisesystems constituting the GEO metasystem) by providing mediation, harmonization and transformation capabilities.
Three types of APIs:• Standard Web Services: standard interfaces which comply with de-iure and de-facto geospatial standards such
as OGC CSW, WCS, WMS, WFS, OAI-PMH, etc.
• Client-side APIs: high level client-side library, designed and developed to facilitate the development of web and
mobile applications, presently available as a Javascript library.
• Server-side APIs: a set of server-side APIs, including OpenSearch and RESTful APIs.
GEO DAB APIs can be used to discover and access GEOSS resources via the GCI.
The APIs are used as well to define and utilize SBA-specific views of the GEOSS resources, i.e. a customized subset of GEOSS resources targeting the needs of the SBA communities.

1. Restyling of the Graphical User Interface
• Aligned with new GEO Web-site and Brand
• Simpler / More Intuitive
• Improvements include: page structures, search & discovery, results display & access
2. Inclusion of smart filters for imagery (Landsat, Sentinel 2) and SAR-type
(Sentinel 1) satellite data and Earthquake events (via Views)
3. My WorkSpace initial set-up (Personalisation/Profiling, Save and reuse searches,
Bookmark results)
4. Geo-localisation services: API,
5. Base maps selection (CartoDB, ESRI, MapBox, OpenStreetMap)
6. Proprietary ESRI data (e.g. regarding active hurricanes, tropical storms)
Enhancements – already implemented - early 2016

1. User-centric, considering various user communities:
• GEO Flagships and Global initiatives
• ESA Thematic Exploitation Platforms
• Copernicus Core Services: Atmosphere (CAMS), Marine (CMEMS), Land (CLMS), Climate (C3S),
Emergency (EMS), Security
2. Additional enhancements considered include:
• My workspace evolution;
• Multi-modality and responsive web-design;
• Statistics;
• GEOSS Portal Reuse: Widgets and Mirroring;
• Visualisation services (e.g. layers, legend, …);
• GEO Like and social collaboration;
• Processing services
Current focus
• Number of users and sessions
• Geographical Distribution
• Use per browser & devices
• Most searched terms / locations/ …
• Resources viewed / loaded on map / downloaded

User-centric Enhancement Approach
1. User Central to Enhancements
2. GCI Enhancements Objectives are user focused
3. Enhancements Areas identified to achieve the objectives
4. Different actual Enhancements identified for the Enhancement Areas
