“…A dense GNSS permanent national network connected to the EUREF Permanent Network (EPN) [65,66] would be ideal for this purpose. In Italy, Istituto Geografico Militare Italiano (IGMI) defined, in 2009, a permanent GNSS network within the EPN project, known as the "Rete Dinamica Nazionale" (National Dynamic Network) and composed of 100 tracking stations (with a spacing between 100 and 150 km) located in and around national borders [67].…”

In the last years, the advanced synthetic aperture radar (SAR) interferometry (InSAR) has proven its effectiveness in the assessment of ground gotion with millimetric accuracy. Its integrated use with traditional (in-situ) topographic height determination techniques, such as geometric leveling and Global Navigation Satellite System (GNSS), is consolidated in underground fluids extraction areas for detecting and monitoring land subsidence. Nevertheless, the lack of a specific standardized methodology does not allow for evaluating different results obtained from different types of analysis. Starting from the description of two independent estimations of land subsidence in the Agosta (Comacchio, Italy) area, where an environmental impact assessment procedure was carried out following a request for gas exploitation, this paper points out the need for a standardized methodology, focused on the in-situ calibration of InSAR data. This last purpose requires an adequately dense and homogeneous reference GNSS network. The in progress initiatives, at European and national level, aiming at providing a Copernicus Ground Motion service could offer the opportunity to structure a reliable and dedicated GNSS network, starting from the large amount of stations run by different institutions already existing in Italy.

“…As early as 1999, at a conference organized by the JRC and the Multi-purpose European Ground Related Information Network, it was jointly agreed that the most appropriate reference system is the European Terrestrial Reference System 89 (ETRS89) [66]. The ETRS89 was adopted in 1990 in Firenze [67]. It uses the Geodetic Reference System 1980 ellipsoid as its reference ellipsoid, the geometric center of the ellipsoid being coincident with the center of the mass of the earth and the origin of the coordinate system.…”

This study addressed a critical resource—soil—through the prism of processing big data at the continental scale. Rapid progress in technology and remote sensing has majorly improved data processing on extensive spatial and temporal scales. Here, the manuscript presents the results of a systematic effort to geo-process and analyze soil-relevant data. In addition, the main highlights include the difficulties associated with using data infrastructures, managing big geospatial data, decentralizing operations through remote access, mass processing, and automating the data-processing workflow using advanced programming languages. Challenges to this study included the reproducibility of the results, their presentation in a communicative way, and the harmonization of complex heterogeneous data in space and time based on high standards of accuracy. Accuracy was especially important as the results needed to be identical at all spatial scales (from point counts to aggregated countrywide data). The geospatial modeling of soil requires analysis at multiple spatial scales, from the pixel level, through multiple territorial units (national or regional), and river catchments, to the global scale. Advanced mapping methods (e.g., zonal statistics, map algebra, choropleth maps, and proportional symbols) were used to convey comprehensive and substantial information that would be of use to policymakers. More specifically, a variety of cartographic practices were employed, including vector and raster visualization and hexagon grid maps at the global or European scale and in several cartographic projections. The information was rendered in both grid format and as aggregated statistics per polygon (zonal statistics), combined with diagrams and an advanced graphical interface. The uncertainty was estimated and the results were validated in order to present the outputs in the most robust way. The study was also interdisciplinary in nature, requiring large-scale datasets to be integrated from different scientific domains, such as soil science, geography, hydrology, chemistry, climate change, and agriculture.

“…Vzpostavljen je bil kakovostno, vendar ima tako zasnovan koordinatni sistem zaradi delovanja tektonike omejen rok trajanja. Distorzije v njem namreč sčasoma postanejo večje od negotovosti, ki so pogojene s kakovostjo GNSS-meritev (Poutanen in Häkli, 2018). Med osnovnimi pogoji za sodoben državni koordinatni sistem, ustrezen za potrebe geodezije in vseh drugih strok, ki se ukvarjajo s prostorom, so tudi kakovostno določene transformacije med tem in mednarodnim sistemom (Sterle in sod., 2009).…”

“…Poznavanje vektorjev hitrosti (iz analiz časovnih vrst koordinat) v teh točkah omogoča kakovostno povezavo med državnim in globalnim referenčnim sestavom. Koordinate točk so tudi v polkinematičnem referenčnem sestavu z vidika uporabnika nespremenljive, vendar je kakovost takšnega sestava zagotovljena za bistveno daljše časovno obdobje, kar zagotavljajo uporabnikom skrite transformacije koordinat, podprte z geokinematskim modelom (Poutanen in Häkli, 2018).…”
