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 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

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)

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)

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
