The project goal is to provide bilateral data exchange with external consumers and sources of information for Ukrainian and European partners of the ERA-PLANET project and the ERA-PLANET/UA Programme on the base of common requirements and solutions of the ERA-PLANET consortium, the GEOSS/GCI data management system support, the European data access regulations compliance, and the quality-of-service requirements considering the infrastructure scalability to support big data. The project main results are: 1) drafts of the related standards (DSTU) have been developed, and the Ukrainian set of signatures has been implemented in the European Digital Signature Service library for all types of containers and documents; 2) 2 variants of mobile cloud geoportal architectures have been developed: – a serverless one based on LeafletJS, – and a fully cloud one based on Google Earth Engine (GEE); 3) for the serverless architecture, a geoportal prototype was developed and tested with the procedures for downloading and displaying the data from various sources documented for programmers, and the software for geoJSON-to-shape format transform has been implemented; 4) for the fully cloud geoportal, the key elements have been developed and documented for JavaScript and Python programmers; 5) the complications of the wave front, amplitude and polarization field were theoretically studied, and the anomalous polarizations has been explained for the orthorhombic anisotropic media and the low symmetry models, the location of singular lines was studied for the orthorhombic media of various types including the pathological and degenerate cases; 6) a mathematical model and a parallel algorithm for solving the 3D static axisymmetric boundary value problems with singularities have been proposed; the algorithm has been implemen Product Description popup.authors Bilodid Orsana O.
