Abstract Increasing amounts of rapidly growing data are the driving force behind proposing and automating new processing, enabling the extraction of useful information from data. One of such possibilities is determining trends to consider in terms of time and space. Thus far, the analysis of these aspects has been separate and lacked automated tools. Therefore, the authors proposed, implemented, and tested a tool for analyzing spatio-temporal linear trends. The tool was tested on PM10 concentration data in the years 2000–2018. The results, presented as cartographic visualization, were then evaluated, both in terms of time and space. The proposed approach facilitates analyzing spatio-temporal trends and assessing their accuracy; it can be developed using other types of analyzed trends or considering additional factors that influence the trend by using cokriging.

Abstract The purpose of the article is to present the research on method of the quality evaluation of published open geospatial data and its implementation in Ukraine. The method of the quality evaluation of open geospatial data considers the international standard ISO 19157 “Geographic information. Data quality”. This method is to determine the number of points or levels (maximum – 5). The research was carried out for the evaluation of open geoinformation resources for production of geospatial datasets, as defined in the Ukrainian Law on NSDI. The authors evaluated the quality of 142 open geoinformation resources and other information resources (materials) for the production and updating of 34 geospatial datasets for the development of NSDI in Ukraine. The authors present the example of the quality evaluation of geospatial data for datasets: “State Geodetic Reference Coordinate System UCS-2000”, “State Geodetic Network”, “Geographical Names” and “Administrative Units” because they are the components of the Core Reference Dataset of NSDI. Limitations of the research were determined by the adopted the Law of Ukraine “On National Spatial Data Infrastructure” and the Order for NSDI functioning in Ukraine and the requirements of the international standard ISO 19157 “Geographic information. Data quality”. The results of the research will be employed to evaluate the quality of NSDI implementation in Ukraine. The proposed method allows evaluating the quality of open geospatial dataset before using them for analysis and modeling of terrain, phenomena. This method takes into account the quality of geospatial data, and its related requirements for their production, updating and publication.

Abstract The aim of this article is to expand the understanding of the history of cartography of the lands of southern Poland under Austrian rule in the nineteenth century. The Austrian Second Military Survey, at the scale 1:28,800, was produced for the province of Galicia between 1861 and 1864 and for Austrian Silesia between 1838 and 1841. In Galicia, work on 413 sheets was led by thirteen cartographers, and the content and descriptions were prepared by 106 cartographic technicians. On the 42 sheets of the Silesia maps, two directors and 11 technicians were recorded. The military cartographers who prepared the survey of the two provinces belonged to 71 multinational units of the army of the Austrian Empire. Work with nineteenth-century maps is fraught with uncertainty about the consistency of the series, which may be reflected in the content of the maps. The consistency of map content was tested on sheets covering the Polish Carpathians for two types of features: linear (roads) and area (forests). Expanding the understanding of these maps may contribute to reducing uncertainty in their use for various environmental and socio-economic analyses.

Abstract This paper sheds light on intersections between teaching and research in the Cybercartographic Residential Schools Land Memory Atlas (RSLMA), which is the central output of the Residential Schools Land Memory Mapping Project (RSLMMP). Building on previous work in Cybercartography, the RSLMMP has further contributed to the integration of research and education and the emergence of new research and education relationships. Viewing the atlas as a project output comprised of iterative processes along multiple dimensions allows us to appreciate limitations as challenges for further iterations, including new related projects and ongoing volunteer work with students. In addition to participating in the national response to the Truth and Reconciliation Commission of Canada’s Calls to Action, this project – including the atlas – provides a model for a unique blend of teaching and research and the basis for further and new collaborations with a variety of different partners, including Residential School survivors. As a reconciliation project, the Residential Schools Land Memory Atlas further contributes to the intercultural bridge building aims of its parent, the Lake Huron Treaty Atlas, as it forges on in new directions.

Abstract Nowadays volunteered geographic information (VGI) and collaborative mapping projects such as OpenStreetMap (OSM) have gained popularity as they not only offer free data but also allow crowdsourced contributions. Spatial data entry in this manner creates quality concerns for further use of the VGI data. In this regard, this article focuses on the assessments of geometric and semantic quality of the OSM building features (BFs) against a large-scale topographic (TOPO) data belonging to some areas of Istanbul. The comparison is carried out based on the one-to-one matched BFs according to a geometric matching ratio. In geometric terms, various parameters of position (i.e. X, Y), size (i.e. area, perimeter and granularity), shape (i.e. convexity, circularity, elongation, equivalent rectangular index, rectangularity and roughness index), and orientation (i.e. orientation angle) elements are computed and compared. In semantic terms, BF type coherences are evaluated. According to the findings of geometric quality, the average positional difference was less than three meters. In addition, the perimeter values tended to decrease while area and granularity values tended to increase in OSM data against TOPO data. Those showed that the level of the detail of the OSM BFs was lower than TOPO BFs in general. This was also confirmed by the decreasing tendency of shape complexity according to the parameters of shape element. Orientation angle differences was often low except for some special cases. It was found that the scale of the OSM dataset, even though not homogenous, approximately corresponded to the lower limit of medium scale maps (i.e. 1:10,000) or a slightly smaller scale. According to the findings of semantic quality, in case of the presence of specific type definition, the coherence was rather high between OSM and TOPO BFs while the most OSM BFs did not have a specific type attribute. This study showed that the matching process needed some improvements while the followed approach was largely successful in the evaluation of the matched buildings from geometric and semantic aspects.
