摘要：The ever increasing penetration of maps - the past decades in the classic web and today in
any ‘connected’ smart device - and any type of potentially associated with them information,
provides high capabilities of disseminating the outputs and results of a project especially
when these are possessing spatial identity. This, combined with the increasingly strict
dissemination requirements set by European Union for the beneficiaries of its funded
Operational Programmes generates reasonable challenges to explore the capabilities of WebGIS
technologies for geospatial data dissemination purposes. Towards this direction, this
paper attempts a review of the EU legislative framework established on top of INSPIRE
directive and dealing with geospatial data and services critical issues such as: Metadata,
Harmonization, Interoperability and Invocability. Through the experiences gained by the
participation of authors in a Black Sea Basin Joint Operational Programme, a Web-GIS end
user interface is presented along with the particularities and special requirements identified
during project implementation. Furthermore, a demonstration of geospatial services
invocability fulfilment is provided along with technical solutions.
