“…Other approaches aimed at a more profound integration by enabling spatial query processing within SPARQL [10,36,37] by implementing a Linked Data connector framework as a set of toolboxes for Esri's ArcGIS to allow the retrieval, integration, and analysis of Linked Data from within GIS [6], or by developing new standards or extensions for spatial and temporal reasoning and querying over Linked Data [38].…”

“…To overcome these limitations and address some critical challenges of GIScience [8], standards (e.g., GeoSPARQL [9]) and domain-dependency best practices for publishing, retrieving, and using geospatial data on the Web have started appearing to propose this new perspective in the GIScience community. Additionally, some tools that combine the Semantic Web best practices and Web GIS have been collected in [10].…”

Geospatial data is increasingly being made available on the Web as knowledge graphs using Linked Data principles. This entails adopting the best practices for publishing, retrieving, and using data, providing relevant initiatives that play a prominent role in the Web of Data. Despite the appropriate progress related to the amount of geospatial data available, knowledge graphs still face significant limitations in the GIScience community since their use, consumption, and exploitation are scarce, especially considering that just a few developments retrieve and consume geospatial knowledge graphs from within GIS. To overcome these limitations and address some critical challenges of GIScience, standards and specific best practices for publishing, retrieving, and using geospatial data on the Web have appeared. Nevertheless, there are few developments and experiences that support the possibility of expressing queries across diverse knowledge graphs to retrieve and process geospatial data from different and distributed sources. In this scenario, we present an approach to request, retrieve, and consume (geospatial) knowledge graphs available at diverse and distributed platforms, prototypically implemented on Apache Marmotta, supporting SPARQL 1.1 and GeoSPARQL standards. Moreover, our approach enables the consumption of geospatial knowledge graphs through a lightweight web application or QGIS. The potential of this work is shown with two examples that use GeoSPARQL-based knowledge graphs.

“…As such, the data model proves to be much more user friendly than complex data models that define the key registers. Access to the current knowledge graph is delivered through REST, GraphQL, GeoSPARQL [15], and ElasticSearch services wherein third-party applications make use of these in delivering geoinformation to the end user [16]. As Figure 3 illustrates, Kadaster's knowledge graph is delivered by creating a layer on top of the key registers in their linked data form.…”

Kadaster, the Dutch National Land Registry and Mapping Agency, has been actively publishing their base registries as linked (open) spatial data for several years. To date, a number of these base registers as well as a number of external datasets have been successfully published as linked data and are publicly available. Increasing demand for linked data products and the availability of new linked data technologies have highlighted the need for a new, innovative approach to linked data publication within the organisation in the interest of reducing the time and costs associated with said publication. The new approach to linked data publication is novel in both its approach to dataset modelling, transformation, and publication architecture. In modelling whole datasets, a clear distinction is made between the Information Model and the Knowledge Model to capture both the organisation-specific requirements and to support external, community standards in the publication process. The publication architecture consists of several steps where instance data are loaded from their source as GML and transformed using an Enhancer and published in the triple store. Both the modelling and publication architecture form part of Kadaster’s larger vision for the development of the Kadaster Knowledge Graph through the integration of the various linked datasets.

“…Going further, one of the development tendencies of GIS is Question Answering (QA), a process for the identification of valid answers to the questions asked by the user in natural language. This implies that the analyst may interrogate certain pieces of spatial information regarding the use of geographical resources, without having the necessary knowledge for understanding the GIS working techniques [34] or the online access to a GIS environment by inexperienced users [35].…”

The Role of UAS–GIS in Digital Era Governance. A Systematic Literature Review

et al. 2021

UAS (Unmanned Aircraft Systems) technologies, also known as UAV (Unmanned Aerial Vehicle), drones, or Remotely Piloted Aircraft System (RPAS) and GIS (Geographic Information System) are recognised for the value of the results that can be achieved by their combined use. However, their use and the results achieved are rarely framed within the context of Digital Era Governance (DEG), an undertaking that would significantly reduce the capabilities of knowledge transfer from the academic and/or private environment to the public domain. The purpose of this study was to highlight, by a bibliometric analysis, the areas of proposed use of this team of tools and the extent to which these can enter the sphere of interest of public administrations, especially local ones. From a methodological point of view, based on the 439 articles filtered from the Web of Science database where UAS/UAV and GIS technologies were used, several bibliometric analyses have emerged. VOSviewer and R (Bibliometrix tool) were used to conduct the bibliometric analyses. Most scientific publications that used UAV technology as a working tool have predominant applicability in photogrammetry, while GIS applications are found in publications dedicated to image processing, landslides, and cultural and archaeological heritage. We point out that from the point of view of international cooperation, at the level of institutions or countries, certain international organisations from the USA, China, and the central and northern European states have a high interest in this topic, and a low cooperation between academia and public administration is exhibited. The conclusion is represented by the apparent lack of framing of the results of UAS–GIS technologies usage into wider and more topical contexts, such as digital era governance, and also a reduced applicability of the research results.
