The document describes EnviroGRIDS, an online portal that aims to build capacities in the Black Sea region to gather, store, distribute, analyze, visualize, and disseminate environmental data using international standards. The portal is designed to be compatible with the Global Earth Observation System of Systems (GEOSS) and the Infrastructure for Spatial Information in Europe (INSPIRE). It functions as a virtual database using principles of Uniform Resource Management and allows users to discover, view, download, and transform spatial data services through tools like catalog services, map services, and processing services. The portal has four blocks for metadata management, data management, data visualization, and content management to ensure users can easily discover and use information.

Introduction
• The Global Earth Observation System of Systems
(GEOSS) has been built by the Group on Earth
Observations (GEO).
• The GEOSS is focused on user needs and support
better utilization of environmental data and decision-
support tools by users
• EnviroGRIDS @ Black Sea Catchment aims at
– building capacities in the Black Sea region,
– to use new international standards to gather, store,
distribute, analyze, visualize and disseminate crucial
information on past, present and future states of this
region, in order to assess its sustainability and
vulnerability.

Introduction
• EnviroGRIDS is building modern Spatial Data
Infrastructure (SDI) that
– is one of components of GEOSS
– is compatible INSPIRE
• EnviroGRIDS GeoPortal is designed as virtual
database.
– It uses principles of Uniform Resource Management
System (URM) and Geoportal4everybody
– It integrates different technologies like Geographic
Information System (GIS), multimedia, Content
Management System, social media.

Objectives
• The main objectives of the implementation of
GeoPortal cover the implementation of following
services:
• Discovery services: supporting discovery of data,
evaluation and use of spatial data and services through
their metadata properties.
• View services: as a minimum, display, navigate, zoom
in/out, pan, or overlay spatial data and display legend
information and any relevant content of metadata
• Download services: enabling copies of complete spatial
data sets or parts of such sets to be downloaded
• Transformation services: enabling spatial data to be
transformed (projection and harmonization)

5. 5 www.envirogrids.net
Objectives
• Invoke spatial data services: enabling data
services to be invoked.
• This implementation is done using Open
Geospatial Consortium (OGC) services
– Web Map Service (WMS),
– Web Feature Services (WFS),
– Web Coverage Services (WCS),
– Web Processing Services (WPS),
– Catalogue Services for Web (CSW)
• All of this services will be made also
interoperable with Grid services

6. 6 www.envirogrids.net
Methodology
• EG portal can be seen from two sides:
– As a client accessing external services.
– As a server making data and services available for other
components of SDI (INSPIRE and GEOSS based) or for GRID
service.
• EG portal supports easy registration of different spatial
services (client). The system offers possibilities to:
– Register services temporally for visualization
– Register services to catalogue
– Connect temporally other catalogue into discovery client of
GeoPortal
– Register catalogue services for harvesting
• EG portal provides tools for users to create services (here is
server)

7. 7 www.envirogrids.net
Development
• The EnviroGRIDS GP is divided into four basic
buildings blocks:
– Metadata management (editing, discovery,
access, harvesting)
– Data management (upload, download, import to
DB, OGC service publishing)
– Data visualization (local data, WMS, WFS, KML
and management of WMC)
– Content management (publishing of context and
connection with social networks)

8. 8 www.envirogrids.net
Development
• EG portal ensures that any user can easily discover,
evaluate and use any type of information.
• Core component of the system is metadata
management system
– It allows to manage any types of information.
– It allows to search and share data using catalogue service
and social networks.
• Tools which are mainly used also in other portals are:
– MIcKA
– HSLayers
– Geoserver

Conclusion
• EG portal is now part of of GEOSS infrastructure.
• Solution supports both major SDI iniatives INSPIRE as
well as GEOSS.
• It can be now used as tool for capacity building in
region.
• Curently it offers:
– List of basic services to integrate data in any region.
– Harvesting of available data and services
– Integrated access point for data in region
• This experiences can be transferred to other regions
including Africa
