Within the project "Increasing the availability of NSDI spatial data through e-services" co-financed from the European Regional Development Fund, view and download network services have been developed and published for data sets within the competence of the NSDI subjects, who responded to the invitation of the State Geodetic Administration to participate in the project. A total of 12 network services were developed in INSPIRE supported standards for network services: WMS, ATOM and WFS for 5 datasets. The development of network services was preceded by two trainings for the harmonization of spatial data and the development of network services, on the basis of which employees of the State Geodetic Administration and selected NSDI subjects were trained for these tasks. Spatial data, for which network services have been developed, have been previously harmonized in accordance with the INSPIRE specifications of selected spatial data themes. Network services have been developed for the following spatial data: State network of hydrological stations of the Croatian Meteorological and Hydrological Service (ATOM, WMS and WFS), Maritime areas of the Adriatic Sea of the Croatian Hydrographic Institute (ATOM and WFS), Unclassified roads of the City of Požega (ATOM, WFS and WMS), Regional civil protection offices of the Ministry of the Interior (ATOM, WFS and WMS) and the Register of Geographical Names of the State Geodetic Administration (ATOM). All services have been implemented on the Hale connect platform, and all metadata of the developed services together with the links are publicly published on the NSDI Geoportal.
