Abstract:
Incorporating geographic knowledge or concepts into machine learning (ML) might help to reduce the required amount of training data and improve the performance and explainability of ML models. A research theme is currently emerging in GIScience and Cartography regarding the development of geospatial artificial intelligence (GeoAI) techniques for geographic knowledge discovery. This presentation will give a summary of our recent research activities in this domain, with a focus on applications in mobility analytics and prediction.

Abstract:
Green areas such as natural and peri-urban parks provide support to biodiversity and landscape preservation while boosting local economic growth in their hosting territories, thanks to the establishment of eco-tourism activities. Smart management and promotion actions are vital for the sustainable exploitation of such benefits for citizens and visitors. These tasks may be hindered by a lack of economic resources and digital skills of public authorities but also by fragmented local political contexts to which these areas may be subjected. The parks in the Insubria region (between Southern Switzerland and Northern Italy) represent a relevant example of the above.

The INSUBRIPARKS project aims at the harmonisation of management and promotion practices for the Insubria parks. The project activities encompass multiple actions, from the establishment of unified territorial marketing strategies to the development of supporting IT tools. Accordingly, the seminar provides an overview of the IT tools ecosystem which was designed and developed within the project and an outlook on its role in empowering smart monitoring and promotion for these parks. Tools include a Web portal (enriched with Web mapping components) for a unified presentation of the tourism offers, an analysis framework for social media data exploitation in park visitors’ fluxes assessment, and a mobile tool for users’ engagement in the park areas monitoring. The mobile app GeoCollectorBot will be presented in detail and will be used in the training.

Abstract: Narrating and visualizing complex and multi-faceted histories tied to archaeological sites can be challenging; especially at sites where tangible histories have vanished from the landscape. Interpreting and narrating on the varied cultural layers bound to these sites when physical remnants are gone require supplemental information and sometimes advanced visualization techniques. Local museums and/or archaeological site centres often have supplemental information and data available but interpreting and building new narratives for these sites is resource intensive. For many lesser known historical sites a resource intensive interpretation and documentation is not feasible.

We are happy to announce our next CartoTalk by Sara Fabrikant
Department of Geography, University of Zurich, on 6 June 2018.

Abstract: We use increasingly dynamic and mobile graphic displays for every-day decision making tasks (i.e., daily commutes in congested cities), and to find solutions to and communicate about complex mobility behaviors. However, we still have a poor understanding on how autonomic nervous activity might influence the already limited perceptual and cognitive resources of display users, for example, in time critical situations or in dilemmatic decision-making contexts (e.g., navigation, disaster mitigation and response, search and rescue, etc.). In this talk, I will highlight ongoing empirical research on animated and mobile graphic display use in the lab and in the wild, capitalizing on ambulatory human behavior sensing methods (i.e., eye tracking, galvanic skin response, and EEG measurements). With this collected empirical data and supported by cognitive/vision theories we are guiding the process of designing user, task, and context responsive graphic interfaces for visual salience and positive engagement. In doing so, we aim to create usable and useful responsive displays to support space-time needs of the increasingly mobile digital citizen.

We are happy to announce a CartoTalk on 14 May 2018 by Nico Van de Weghe from Gent University.

Abstract: In this Cartotalk, the interdisciplinary projects UGESCO and EURECA will be presented. In this ongoing work, an interdisciplinary approach (Natural Language Processing, Computer vision, Metadata analysis, Spatio-temporal querying and visualization, and LBS) is followed. In this cartotalk, an overview of the project will be given (with specific focus on the Geo-ICT aspects), as well as avenues for future research and cooperation.

In UGESCO/EURECA, we focus on finding traces of European regions that have shaped the cities in which we live today, and we develop tools to easily explore them when visiting a city. Different historical, architectural, economic, political and cultural reasons form the base of these traces, and we use input from each of these domains to reveal the cultural heritage items that can be linked to these specific European regions/origins. The enriched metadata that is generated for the city archives and collections can be used as input to perform new fundamental research and applied studies, but also to facilitate the exploitation of the collections to a broader public and attract new groups of cultural heritage consumers. LBS that run on top of our enrichments, for example, will allow tourists to explore the traces of a specific European region (e.g. Austria) in the city (e.g. Ghent) and show them the collection items at their corresponding point of interest (POI) using their mobile device.

Nico Van de Weghe is professor in geomatics at the Department of Geography (UGent, Belgium). He is specialized in the tracking of moving objects; visualizing, analyzing and modeling of spatiotemporal information; and cognition and linguistics of moving objects. On the one hand, he has a broad experience in fundamental research with respect to handling moving objects (going from accuracy issues in data acquisition, over analyzing, reasoning, modelling and data-mining, towards visualizing and visual analytics). On the other hand, he gained a wide experience in setting up experiments in the area of Geographical Information Technology (e.g. research of the movement behaviour of persons at mass-events). Nico is author of more than 80 papers referenced on the Web-Science.

We are happy to announce a CartoTalk by Evangelos Livieratos, Aristotle University of Thessaloniki, on 14 May 2018.

Abstract: Modern digitisation offer better ways to investigate differences and similarities between old and modern maps, useful for a variety of theoretical investigations and practical applications in a large number of fields, from humanities and social sciences to geographical and engineering issues. Proper digitisation is thus important for obtaining the required material in order to proceed in a proper comparison of maps which is dependent on selected analytical transformations satisfying properties appropriate for the type of map comparisons nedded. Some simple practical guidelines for proper digitisation will be presented as well as the types of transformations, and their properties, to be implemented according to the given specific purpose to achieve in a project focused on an old and modern map comparison.

We are happy to announce a CartoTalk by Lynn Usery, U.S. Geological Survey, on  Wednesday, 9 May 2018.

Abstract: The discipline of cartography has traditionally advanced with technological innovation. Hand-drawn maps, copper plate engraving, pen and ink developments, photographic film, scribecoat, and computer-assisted mapping represent innovations that changed cartographic theory and practice. The development and evolution of the World-Wide Web and the Semantic Web are changing cartography to be more interactive, inclusive, ubiquitous, and provide for mapping concepts, ideas, emotions, and other human phenomena not previously mapped. These advances also provide for machine interpretation of maps as knowledgebases representing a new stage in the evolution of cartography in which maps become the basis of artificial intelligence applications, such as self-driving cars and new business models based on map availability to machines and humans using those machines. The U.S. Geological Survey (USGS) is creating semantic representations of topographic maps to support human and machine interpretation and applications of geospatial data. This presentation documents the basis of this representation and production using Semantic Web technologies. The USGS has developed a geospatial ontology for topographic map data and converted specific datasets from The National Map to the Resource Description Framework (RDF) triple model of subject, predicate, and object on the Semantic Web. The process involves representing the ontology and the instance data, i.e., feature identifiers, coordinates, attributes, and relationships of the geospatial entities, in RDF as a triplestore and knowledgebase. The guiding concept to this work is the map as a knowledge base. The map itself becomes an interactive window to access the knowledgebase (triplestore) through direct query with the SPARQL Protocol and RDF Query Language and/or through a point and click interface in which clicking any geographic feature on the interactive graphic spawns a browseable graph approach providing the characteristics of that feature and connecting to associated features in the Linked Open Data cloud.

E. Lynn Usery is a Senior Scientist of the U.S. Geological Survey (USGS) and Director of the Center of Excellence for Geospatial Information Science (CEGIS). He worked as a cartographer and geographer for the USGS for more than 28 years and a professor of geography for 17 years with the University of Wisconsin-Madison and the University of Georgia. He served as President of the University Consortium for Geographic Information Science (UCGIS), the Cartography and Geographic Information Society (CaGIS), and the American Society for Photogrammetry and Remote Sensing (ASPRS). He is a Fellow of CaGIS and UCGIS, and received the CaGIS Distinguished Career Award in 2012. Dr. Usery is currently Vice-President of the International Cartographic Association.

We are happy to announce a CartoTalk by Menno-Jan Kraak, University of Twente, on  Wednesday, 9 May 2018.

Abstract: The content of an Origin and Destination matrix informs about the nature of movement and connectivity between locations. These could be point locations, like airports, or regions, like countries. The type of movement or flow can be qualitative (different airline flying between two airports) or quantitative (the number of migrants between two countries), or both. Traditionally this type of data is visualized in flowmaps. In these maps flows are often represented by arrows of different colors and width to represent the character of the flow between an origin and a destination. However, flow maps also tent to become quickly visually cluttered. Additional problems arise when time series have to be displayed too. How to solve this problem? A link between alternative visualizations, such as cartograms, chord diagrams, tree maps etc. could be useful, but in some of these alternative approaches the geography gets lost and time is lacking. In our suggested solution we concentrate on the design of alternative visualizations of the matrix itself. The matrix represents attribute space and will be linked to the (flow) map. The presentation will discuss several options on how to include time in these visualizations as well. Among the alternatives are several three-dimensional designs that allow for interaction to brush time
