Recent years have seen a growing trend to integrate spatial analysis and geovisual analytics inside Geoportals. Researchers could use the Geoportal to conduct basic analysis without offline processing. In practice, domain-specific analysis often requires researchers to integrate heterogeneous data sources, leverage new statistical models, or build their own customized models. These tasks are increasingly being tackled with open source tools in programming languages such as Python or R. However, it is unrealistic to incorporate the numerous open source tools in a Geoportal platform for data processing and analysis. This work provides an exploratory effort to bridge Geoportals and open source tools through Python scripting. The Geoportal demonstrated in this work is the Urban and Regional Explorer for China studies. A python package is provided to manipulate this platform in the local programming environment. The server side of the Geoportal implements a set of service endpoints that allows the package to upload, transform, and process user data and seamlessly integrate them into the existing datasets. A case study is provided that illustrated the use of this package to conduct integrated analyses of search engine data and baseline census data. This work attempts a new direction in Geoportal development, which could further promote the transformation of Geoportals into online analytical workbenches.

Valuable components of CyberGIS : Expert viewpoints through Q‐method interviews / Forrest J. Bowlick in Transactions in GIS, vol 22 n° 5 (October 2018)

This fusion combines the technical capabilities of advanced cyber‐infrastructure with the spatial analysis capabilities of GIS. How expert GIS practitioners perceive, use, and value the various components of CyberGIS is unknown, making student preparation for CyberGIS competency difficult. To address this gap, we reviewed the CyberGIS literature to develop a set of 37 key CyberGIS concepts. Then, we used Q‐methodology to interview 20 expert GIS users to understand the components of CyberGIS they viewed as most applicable to their GIS practice. Three distinct conceptions of CyberGIS expertise emerged: the spatial analyst, the domain‐specific problem solver, and the CyberGIS‐enabled computer scientist. The CyberGIS‐enabled computer scientist emphasized the underlying technologies which allow spatial analysts to discover and implement advanced methods and processes in GIS, which are then utilized by problem solvers to address domain‐focused issues. These three contrasting perceptions of CyberGIS expertise raise questions about the nature of curriculum and instruction appropriate to develop competent CyberGIS practitioners. With the identified variety of expert practices concerning CyberGIS, confusing practices and contrasting visions of the nature of CyberGIS reveal a need for instructional organization.

Opening GIScience : A process-based approach / Jerry Shannon in International journal of geographical information science IJGIS, vol 32 n° 9-10 (September - October 2018)

These practices have made both research and data more transparent and accessible for a broad audience. This research may be open only in a limited sense for populations without expertise in the technology and methods undergirding these data. Based on two case studies using RStudio’s Shiny web platform, we argue that a process-based approach focusing on how analysis is opened throughout the research process provides a supplementary way to define and reflect upon public facing geographic research. Reflecting upon decisions we made at key points in each case study project, we identify four key tensions inherent to work in open GIScience: standardized vs. flexible tools, expert vs. community-led design, single vs. multiple audiences and established vs. emerging metrics.

Information regarding jurisdiction, as well as the effects of formal law and community interests on the marine environment should be stored in a marine cadastre. The aim of the presented research is to present a concept marine cadastre structure for the EU Member State of Poland as well as show the potential of the application of open standards and Geovisual Analytics for the purpose of marine cadastre data integration, dissemination and analysis with the use of a Geographic Information System (GIS). The paper also presents a sample implementation of the proposed concept in the form of a Web-GIS for analysis and visualisation of risk assessment results in the context of a marine cadastre for the country of Poland.

3D WebGIS : from visualization to analysis. An efficient browser-based 3D line-of-sight analysis / Michael Auer in ISPRS International journal of geo-information, vol 7 n° 7 (July 2018)  

Public [article]  inISPRS International journal of geo-information > vol 7 n° 7 (July 2018) Titre : 3D WebGIS : from visualization to analysis. An efficient browser-based 3D line-of-sight analysis Type de document : Article/Communication Auteurs : Michael Auer, Auteur ; Alexander Zipf, Auteur Année de publication : 2018 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géomatique web [Termes descripteurs IGN] analyse spatiale [Termes descripteurs IGN] base de données localisées 3D [Termes descripteurs IGN] HTML [Termes descripteurs IGN] ligne de visée [Termes descripteurs IGN] optimisation (mathématiques) [Termes descripteurs IGN] visualisation 3D [Termes descripteurs IGN] webGL [Termes descripteurs IGN] WebSIG Résumé : (Auteur) 3D WebGIS systems have been mentioned in the literature almost since the beginning of the graphical web era in the late 1990s. The potential use of 3D WebGIS is linked to a wide range of scientific and application domains, such as planning, controlling, tracking or simulation in crisis management, military mission planning, urban information systems, energy facilities or cultural heritage management, just to name a few. Nevertheless, many applications or research prototypes entitled as 3D WebGIS or similar are mainly about 3D visualization of GIS data or the visualization of analysis results, rather than about performing the 3D analysis itself online. This research paper aims to step forward into the direction of web-based 3D geospatial analysis. It describes how to overcome speed and memory restrictions in web-based data management by adapting optimization strategies, developed earlier for web-based 3D visualization. These are applied in a holistic way in the context of a fully 3D line-of-sight computation over several layers with split (tiled) and unsplit (static) data sources. Different optimization approaches are combined and evaluated to enable an efficient client side analysis and a real 3D WebGIS functionality using new web technologies such as HTML5 and WebGL.
