This article continues a description of the EarthLookCZ project with special focus on the geo-spatial data sharing functionality of the GMES national portal prototype. Publication of geo-spatial data on the web, usage of GMES data stored on remote sources (external servers) and possibilities to create new web map services from such mixed data sources have been the biggest challenges of the project. Individual components for geo-spatial data management, such Dataman, MapMan or HSLayers are, have been modified and integrated together with new components into new Czech national GMES portal prototype in order to make GMES data accessible to common users.

Use of data sources by means of web services will become more and more significant. The solution of using web services as a basis for creating a new web service represents a way to effectively and purposefully employ data sources in making new values. As a web tool for management of spatial data of various forms and sources Map Project Manager represents a significant innovative solution, which ensures easy accessibility of external data sources, a possibility to create new services, and owing to its ability of working together with other SW components it ensures also an easy integration into complex solutions, as is the case for example with Geohosting. The technological concept of Geohosting and its incorporation into the EarthLookCZ portal facilitate publication of users’ geographical GMES data, their combination with remote data sources and possible updating in situ not only for large companies and institutions, but basically for every user working with spatial data. The solution is based on the INSPIRE principles and provides publication of users’ data including a standardized metadata record, searching for external data sources through the metadata catalogue, reduction of data replication through utilization of web services, and creation of new sources accessible in the form of web services.
Principles from EarthLookCZ project could be useable for agricultural issues as well.
