Abstract. Knowledge graphs (KG) are a virtual layer connecting disparate databases into an interoperable framework. Though the application of KGs for enterprises are increasing, geospatial KG design is not common. This presentation describes U.S. Geological Survey (USGS) research to build KGs for integrating geospatial and non-spatial attribute semantics of topographic data. Those geographic information system databases are composed of various feature types and metadata attributes organized various themes and stored in different data formats, such as geodatabases, flat-file spreadsheets, and raster images. The system being created tests two research objectives: 1) the feasibility of semantic technology approaches for geospatial data within the context of national topographic data and 2) the contribution to building a body of knowledge about system architecture for geospatial ontologies and linked open data. This presentation discusses the context of topographic data semantics, the problem and aims of building the system, and the integrated KG framework. The basic workflow and operations of the system architecture consisting of open-source software are described. The architecture modifies existing software with unique solutions such as performing GeoSPAQL queries with Postgres, a relational table datastore, and a map interface with extensions to support linked data queries as browseable graphs. As public spatial data infrastructure, the system is made available as a Docker Container on GitHub.

Nowadays, the availability of authoritative geospatial features of various data themes is becoming wider on global, regional and national levels. The reason is existence of legislative frameworks for public sector information and related spatial data infrastructure implementations, emergence of support for initiatives as open data, big data ensuring that online geospatial information are made available to digital single market, entrepreneurs and public bodies on both national and local level. However, the availability of authoritative reference spatial data linking the geographic representation of the properties and their owners are still missing in an appropriate quantity and quality level, even though this data represent fundamental input for local governments regarding the register of buildings used for property tax calculations, identification of illegal buildings, etc. We propose a methodology to improve this situation by applying the principles of participatory GIS and VGI used to collect observations, update authoritative datasets and verify the newly developed datasets of areas of buildings used to calculate property tax rates issued to their owners. The case study was performed within the district of the City of Požega in eastern Croatia in the summer 2015 and resulted in a total number of 16072 updated and newly identified objects made available online for quality verification by citizens using open source geospatial technologies.

This research paper analyzes how the value of open data varies based on the goal of the open data program, and the format in which the data are provided. Four cities across Canada which make up the G4 are examined to identify common themes of open data available, and assess the data formats found most often within these themes. Further, the City of Toronto is examined in a case study to evaluate their open data program and assess if spatial open data are more prevalent within the theme of innovation for economic development. Findings from this research indicate that there are some data themes which typically have mostly spatial and/or non-spatial data formats, while there is also a group of themes which have a wide variety of both formats available. This paper also finds that the City of Toronto has a high prevalence of spatial open data within the theme of innovation. The evaluation created for this study could be used in assessing the value of spatial open data within and between cities.

Concept Of Information

Central to the entire discipline of heritage restoration and conservation is the concept of information management. Nevertheless, traditionally, conservation and restoration has been a poorly documented discipline, which has led not only to a lack of standardization and awareness about the processes carried out in the past, but also poses problems both when new restoration works are necessary and for the preventive conservation of the elements of heritage. This study sets out to propose a conceptual framework to explore the relationship between conservation of heritage and information management on the basis of case studies; in particular: a spatial data infrastructure (SDI) of a regional government concerning an endangered plant (wild grapevine) with an important potential for cultural and touristic uses in a wine-making region; an open data guide—the Digital Guide of Andalusian Cultural Heritage; a university repository connected to Europeana, which contains reports and outcomes of projects of geometric documentation of elements of heritage; a repository of an organization in charge of the protection and care of the heritage; and finally, two examples of the use of heritage building information models (HBIM) in complex monuments. After discussing the characteristics of each case, this paper concludes that, although the availability of information and tools is growing, further progress is still necessary concerning the interoperability, outreach and reuse of the different solutions.

Data Portal

The new Lamma Open Data platform (http://dati.lamma.toscana.it) allows data download related to information delivered / managed by the Consortium, encouraging the reuse both at technical and legal level. The datasets, over 220, belong to the weather forecast and geospatial topics above all, but they are in continuous updating, both spatial and no spatial (such as administrative documentation). Lamma open data platform integrates in a harmonised interface, most off the spatial dataset already available through the Lamma geoportal (http://geoportale.lamma.rete.toscana.it/MapStore/public/), now available for download as open data. The particularity of meteorological information is their organization in models, archives and formats according to the type of information, source of acquisition and level of elaboration. These formats are not all functional or directly manageable in their entirety, as data to be made available and immediately accessible. The datasets therefore require a preliminary phase of evaluation and analysis of the contents to identify the most appropriate elements for publication via filters and elaborations that maintain the significance of the variables to be highlighted. A synergic and integrated infrastructure for spatial data has been carried out through open source softwares. The LaMMA Geoportal integrates, in a single simple but powerful interface, the functionalities of research, display and download of the available data. This objective is to provide a ready-to-use tool for all users who do not intend to connect directly to the services offered or to download (and therefore reutilize) the data: in this case we relied on the software Open Source MapStore. The open data platform is directly connected to the Geonetwork metadata catalogue that in turn automatically provide a real-time ingestion of datasets in geoportal. The Lamma open data infrastructure has been implemented by the use of CKAN software. All the datasets are made available according to the CC-BY license - Attribution Creative Commons. That choice will allow an easier federation with Open Tuscany (http://dati.toscana.it/), the open data portal of Tuscany Regional Government that until now has hosted, as supplementary task, some Lamma Consortium datasets. The open data infrastructure has been implemented thanks to the Life+IMAGINE European contribution and with the support of the Geosolutions company.

Spatial information is an essential component in almost all decision support system due to the capability it provides for analyzing anything that has reference to the location on earth. Spatial data generally provides thematic information of different aspects over a region. Geospatial information, a variant of spatial information, is generally collected on thematic basis, where individual organizations are involved on any particular theme. Geospatial thematic data is being collected from decades and huge amount of data is available in different organizations (Stoimenov, Dordevi´c, & Stojanovi´c 2000). Information communities find it difficult to locate and retrieve required geospatial information from other geospatial sources in reliable and acceptable form. The problem that has been incurred is the lack of standards in geospatial data formats and storage/access mechanism (Devogele, Parent, Spaccapietra, 1998). Heterogeneity in geospatial data formats and access methods poses a major challenge for geospatial information sharing among a larger user community. With the growing need of geospatial information and widespread use of Internet has fostered the requirement of geospatial information sharing over the Web. The Geo-Web (Lake, Burggraf, Trninic, & Rae, 2005) is being envisioned to be a distributed network of interconnected geographic information sources and processing services that are: • Globally accessible, that is, they live on the internet and are accessed through standard Open Geospatial Consortium (OGC) and W3C interfaces, • Globally integrated data sources that make use of standard data representation for sharing and transporting geospatial data. Unless a standard means for geospatial information sharing is developed, interoperability cannot be realized. Without successful interoperability approaches, the realization of Geo-Web is not possible. Geo-Web is being developed to address the need for access to current and accurate geospatial information from diverse geospatial sources around the world. The National Spatial Data Infrastructure (NSDI) initiative has been taken by many nations for providing integrated access of geospatial information (Budak, Sheth, & Ramakrishnan, 2004). Actual data will be kept under the jurisdiction of the organization producing that data. A user will be interested in availing geospatial services through well-defined interface. Without some internationally agreed upon standards for geospatial data and computational methodology, this cannot be made into existence. This chapter discusses several issues towards geospatial interoperability and adoption of geography markup language (GML) (Cox, Cuthbert, Lake, & Martell, 2001; Lake et al., 2005) as a common geospatial data format. The associated technologies that can be used for realizing geospatial interoperability have also been discussed.
