Romania is covered by more than one hundred GNSS (Global Navigation Satellite System) permanent stations, that have been set up over the last seven years, maintained by different agencies and having different technical architectures and scientific objectives. Many of these stations provide support for geo-referencing applications such as surveying, the network being developed by National Agency for Cadaster and Land Registration (ANCPI) and by a private company, TopGeocart. Two networks are developed with scientific purposes: one developed by the National Institute for Earth Physics - NIEP and the other one developed by the National Institute for Research and Development on Marine Geology and Geo-ecology – GeoEcoMar. Several limiting factors were identified in terms of utilization: no site uniqueness, no file redundancy, no quality control or hardwire web service. Our goal is to collect all those GNSS data in order to standardize, perform quality control and harmonize for creating the metadata.
We present and discuss step by step all the implementation levels of standard tools necessary for generating, validating and disseminating pre-defined GNSS metadata, tools for the generation and dissemination of metadata. All those will allow the end-users, and in particular, geoscientists, to freely access the geodetic data, derived solutions, and associated metadata using a transparent and standardized process. Finally, we detail the technologies and software that were used and developed to build this e-infrastructure, the system output data and the conclusions derived in terms of data volume, security and usefulness.
The involvement in EPOS – IP project as a member of GNSS Data and Products Working Group helps us evolve in the same direction, test and implement GLASS software package for the dissemination of GNSS data & dedicated processing outcomes, time-series, velocities, and strain-rates - to be created using state-of-the-art methodologies for a better understanding and completion of the tectonic puzzle pieces of Solid Earth processes in this challenging structure of Southeastern Europe.
