The SEE-GeoForm WebGIS: a tool for seismic data and hazard analysis
The SEE-GeoForm project (Site Effects Evaluation - Geological Form) is born to share and make easily accessible via Internet seismic hazard data for Italy at different scales and for different administrative units (regions, provinces, municipalities), from existing database or new dataset carried out in this project. Using a WebGIS (http://www.seegeoform.it) a tool to archive, display and elaborate information has been developed. In particular, the website allows the user to query the basic and local seismic hazard values for single municipalities or to calculate those for any single point only by clicking on the maps.
In order to make the WebGIS more flexible, the system has been fully implemented using open source technologies, based on the guidelines expressed by the Open Geospatial Consortium (OGC); in this way, it has been possible to develop some thematic modules for data elaborations and queries as integrated web services such as WMS, following all of the internationally-acknowledged best-practices in this field.
The WebGIS has three frames: the data panel, the display area, the map layers directories. The data panel has several modules concerning respectively: basic and local hazard data for all Italian municipalities calculated by National Institute of Geophisics and Volcanology (INGV) or from other studies, such as horizontal peak ground acceleration values for different return periods (considering the exceedance probability in 50 years), and soil classes with the corresponding lithostratigraphic amplification factors according to the EuroCode8; a regular grid of 16.810 points, with a step equal to 0.05°, used by INGV for the seismic hazard elaborations (http://zonesismiche.mi.ingv.it/): values that are necessary to draw the site-dependent response spectra, according to the Italian seismic code, are linked to each point; the calculation on user demand of basic seismic hazard parameters for a site selected by clicking on geographical layers; composite seismogenic sources from DISS (Database of Individual Seismogenic Sources, vers. 3.1.1.: http://diss.rm.ingv.it/diss/), with their relative parameters (maximum moment magnitude, strike, dip, etc.). Finally, there are two modules regarding litoseismic classes and subsoil categories: the first one is linked to a map obtained by reclassifying the 46 litothypes of the Lithological Map of Italy at 100000-scale by Geological Survey of Italy (National Institute for Environmental Protection and Research - ISPRA) into 12 litoseismic classes, considered homogeneous regarding to their seismic behavior; while the second one permits to know the subsoil category, according with Italian seismic provisions (Norme Tecniche per le Costruzioni – NTC 2008), for a single point by clicking on the map. This has been possible by elaborating a subsoil categories map at 100000-scale derived from the litoseismic map at the same scale, by blending different litoseismic classes into 5 categories.
Datasets have been built starting from 2007 within the ReLUIS Project (http://www.reluis.it) and are being improved within the 2009-2012 EUCENTRE project (http://www.eucentre.it), that partially financed the WebGIS development, as a result of the strong collaboration between researchers from INGV and ISPRA.
The SEE-GeoForm web-tool aims to become the focal point to display in a simple way many databases containing information on seismic hazard of Italian territory, allowing user-friendly elaborations for researchers and professionals
Il Progetto SEE-GeoForm: uno strumento per la consultazione di dati geologici e di pericolosità sismica riferiti all’intero territorio nazionale
Il progetto SEE-GeoForm (Site Effects Evaluation - Geological Form: http://www.seegeoform.it) nasce con
l’obiettivo di realizzare uno strumento semplice, potente e completo per la consultazione e la rappresentazione,
tramite un WebGIS, di dati geologici, geomorfologici, geotecnici e geofisici relativi all’intero territorio italiano. In
questo modo, si vogliono concentrare in un sistema flessibile e intuitivo, dotato di un’unica modalità di accesso e
consultazione, una serie di informazioni che attualmente sono disperse in numerosi database mono-tematici
consultabili via Internet. Attualmente il WebGIS contiene dati georeferenziati e carte tematiche relative alla
pericolosità sismica a differenti scale territoriali e per diverse unità amministrative (regioni, province e comuni). Le
informazioni provengono sia da banche dati esistenti che da elaborazioni effettuate “ad hoc” nell’ambito di questo
progetto (carte tematiche in scala 1:100.000 del territorio italiano). Per rendere il sistema più flessibile ed
aggiornabile è stata sviluppata una piattaforma che utilizza esclusivamente tecnologie “open source”, basate sulle
linee guida dell’Open Geospatial Consortium (OGC); in questo modo è stato possibile realizzare alcuni moduli
tematici che sono totalmente compatibili con il protocollo standard denominato WMS (Web Map Services) per la
consultazione e la visualizzazione spaziale dei dati tramite Internet
Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes
Background: Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage 653 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage 653 CKD in a large cohort of patients affected by T1DM. Methods: A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD) initiative constitutes the study population. Urinary albumin excretion (ACR) and estimated GFR (eGFR) were retrieved and analyzed. The incidence of stage 653 CKD (eGFR < 60 mL/min/1.73 m2) or eGFR reduction > 30% from baseline was evaluated. Results: The mean estimated GFR was 98 \ub1 17 mL/min/1.73m2 and the proportion of patients with albuminuria was 15.3% (n = 654) at baseline. About 8% (n = 337) of patients developed one of the two renal endpoints during the 4-year follow-up period. Age, albuminuria (micro or macro) and baseline eGFR < 90 ml/min/m2 were independent risk factors for stage 653 CKD and renal function worsening. When compared to patients with eGFR > 90 ml/min/1.73m2 and normoalbuminuria, those with albuminuria at baseline had a 1.69 greater risk of reaching stage 3 CKD, while patients with mild eGFR reduction (i.e. eGFR between 90 and 60 mL/min/1.73 m2) show a 3.81 greater risk that rose to 8.24 for those patients with albuminuria and mild eGFR reduction at baseline. Conclusions: Albuminuria and eGFR reduction represent independent risk factors for incident stage 653 CKD in T1DM patients. The simultaneous occurrence of reduced eGFR and albuminuria have a synergistic effect on renal function worsening
Un modello concettuale di banca dati per l’informatizzazione di carta geomorfologica
Sulla base di alcuni rilevamenti geomorfologici condotti e finalizzati alla realizzazione di cartografie digitali, è stato messo a punto un modello fisico di banca dati, al fine di rendere gli eventuali database geomorfologici utilizzabili per l’allestimento di carte geomorfologiche a diversa scala. Il modello di banca dati proposto prevede la possibilità di sfruttare le informazioni anche per realizzare carte geotematiche di vario tipo e per effettuare analisi geomorfologiche quantitative più specifiche (Cipolloni et alii, 2005a). Sono stati identificati 5 insiemi di informazioni, provenienti non solo dal database geomorfologico ma anche dagli archivi dei progetti CARG e IFFI. Il modello concettuale è stato sviluppato a partire dalle linee guida della carta geomorfologica alla scala 1:50.000 (AA.VV., 1994), implementando attributi utili alla gestione della cartografia a scala multipla e alla valutazione e analisi della cronologia dei processi morfogenetici
Il portale del servizio geologico d'Italia
The italian geological service Geoportal
On may 25th, ISPRA, Institute for Environment Protection and Research, presented the Web Service for the new portal of Geologic Survey of Italy. Through simple tools it allows to search and examine documentation and databases owned by Italian Geologic Survey. It consists in two different levels: the first one is a searchable repository of metadata of databases stored within SGI-ISPRA and from external web services and the latter is a WebGIS interface that shows geological, geophysical and other environmental data surveyed and produced at different scales. All metadata are compliant with ISO 19119 and 19115 standards. INSPIRE and OGC compliant web services WMS, WCS and WFS are available as well as other formats like ESRIArcGIS and KML /KM
Integration of European boreholes data and their dissemination through international interoperable standards
International audienceThe Geological information and modelling Thematic Core Service (TCS) of EPOS is designed as an efficient and sustainable access system for geological multi-scale datasets for EPOS. The TCS develops and benefits from the synergy between the existing data infrastructures of the Geological Surveys of Europe (EuroGeoSurveys / EGDI) and the large amount of information produced by the research organizations and the international drilling community. The integration of distributed infrastructure components allows a broad range of resources including: geological maps, borehole data, borehole associated observations (borehole log data, groundwater level, groundwater quality…) and archived information on physical material (samples, cores), geological models (3D, 4D), geohazards, geophysical data such as active seismic data and other analyses of rocks, soils and minerals. In this presentation, we focus on the European Borehole Index and the work done since the beginning of the project, first to specify an interoperable data exchange mechanism based on international standards (such as INSPIRE, OGC) implemented by all TCS data providers. Then to collect this information from the data provider, quality check and disseminate it from the TCS Central Node as a service provider to the EPOS community using the same interoperable standards. We will develop on the problems encountered to manage large amount of data and the solutions we tested and applied. We will present how the Borehole Index was specified in order to guarantee its compliance with INSPIRE European Directive and how the OGC community was engaged to improve and promote technologies for geoscience data description and sharing through its Geoscience Domain Working Group. In addition, we will present expected workflows for the integration of other existing and new data such as 3D/4D models and how our work fits in EPOS system to create an efficient and comprehensive multidisciplinary research platform for the Earth Sciences in Europe and abroad

Nell'ultimo decennio gli straordinari sforzi tecnologici hanno evoluto il settore geomatico e portato enormi vantaggi nell'ambito dei cosiddetti servizi a valore aggiunto. Tuttavia la svalutazione commerciale del sistema di navigazione satellitare ha fatto del navigatore un oggetto di uso comune, quasi alla pari del più quotato telefono cellulare. Scemata la corsa al cellulare più modaiolo è subentrata quella al navigatore satellitare più tecnologico con cartografia e punti di interesse più aggiornati. E' assai frequente trovare commercializzazioni degli operatori di telefonia che uniscono
al dispositivo mobile il sistema di navigazione, grazie anche a
politiche di businness agreement tra le varie major. L'utilizzo dei dispositivi GPS è davvero ancora arenato alla semplice ricerca di un percorso o di un indirizzo da raggiungere? L'uso di tali apparecchiature può inserirsi all'interno di target quali l'intrattenimento e le attività ricreative? Negli ultimi anni stiamo riscoprendo la bellezza della natura e il piacere di dedicarci ad una serie di attività sportive outdoor che ci conciliano con essa, unendo ai benefici della mente quelli del corpo derivanti da una corretta sollecitazione della propria frequenza cardiaca. Questa mia relazione vuole essere un diario di viaggio nelle quotidiane attività all'aria aperta di un atleta non professionista, praticate durante le quattro stagioni sfruttando le tecnologie legate alla triangolazione satellitare
