The role of generalization in thematic mapping(MDPI, 2020) Raposo, Paulo; Touya, Guillaume; Bereuter, PiaCartographic generalization research has focused almost exclusively in recent years on topographic mapping, and has thereby gained an incorrect reputation for having to do only with reference or positional data. The generalization research community needs to broaden its scope to include thematic cartography and geovisualization. Generalization is not new to these areas of cartography, and has in fact always been involved in thematic geographic visualization, despite rarely being acknowledged. We illustrate this involvement with several examples of famous, public-audience thematic maps, noting the generalization procedures involved in drawing each, both across their basemap and thematic layers. We also consider, for each map example we note, which generalization operators were crucial to the formation of the map’s thematic message. The many incremental gains made by the cartographic generalization research community while treating reference data can be brought to bear on thematic cartography in the same way they were used implicitly on the well-known thematic maps we highlight here as examples.01A - Beitrag in wissenschaftlicher ZeitschriftPublikation A Change of theme.

The method works in indoor and outdoor environments and does not require the presence of control points or markers. The method is evaluated with different sensors in an outdoor and an indoor test field. The results of our research show the viability of single image localization with absolute position accuracies at the decimetre level for outdoor environments and 5 cm or better for indoor environments. However, the evaluation also revealed a number of limitations of single image visual localization in real-world environments. Some of them could be addressed by an alternative AR-based localization approach, which we also present and compare in this paper. We then discuss the strengths and weaknesses of the two approaches and show possibilities for combining them to obtain accurate and robust visual localization in an absolute coordinate frame.04B - Beitrag KonferenzschriftPublikation Achieving More Sustainable e-Learning Programs for GIScience(Canadian Science Publishing, 2009) Weibel, Robert; Bleisch, Susanne; Fisler, Joël; Grossmann, Thomas; Niederhuber, Monika; Nebiker, Stephan; Hurni, Lorenz01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Achieving More Sustainable e-Learning Programs for GIScience(Canadian Science Publishing, 2009) Weibel, Robert; Bleisch, Susanne; Fisler, Joël; Grossmann, Thomas; Niederhuber, Monika; Nebiker, Stephan; Hurni, Lorenz01A - Beitrag in wissenschaftlicher ZeitschriftPublikation Advances in imaging and photogrammetry(Gateway Media, 01.08.2012) Nebiker, Stephan01B - Beitrag in Magazin oder ZeitungPublikation AI-based 3D detection of parked vehicles on a mobile mapping platform using edge computing(2022) Meyer, Jonas; Blaser, Stefan; Nebiker, StephanIn this paper we present an edge-based hardware and software framework for the 3D detection and mapping of parked vehicles on a mobile mapping platform for the use case of on-street parking statistics. First, we investigate different point cloud-based 3D object detection methods on our extremely dense and noisy depth maps obtained from low-cost RGB-D sensors to find a suitable object detector and determine the optimal preparation of our data. We then retrain the chosen object detector to detect all types of vehicles, rather than standard cars only. Finally, we design and develop a software framework integrating the newly trained object detector. By repeating the parking statistics of our previous work (Nebiker et al., 2021), our software is tested regarding the detection accuracy. With our edge-based framework, we achieve a precision and recall of 100% and 98% respectively on any parking configuration and vehicle type, outperforming all other known work on on-street parking statistics. Furthermore, our software is evaluated in terms of processing speed and volume of generated data. While the processing speed reaches only 1.9 frames per second due to limited computing resources, the amount of data generated is just 0.25 KB per frame.04B - Beitrag KonferenzschriftPublikation Aktivitäten im Bereich NGDI am Institut Vermessung und Geoinformation der FHNW(e-geo.ch, 01.04.2007) Nebiker, Stephan; Stark, Hans-Jörg01B - Beitrag in Magazin oder ZeitungPublikation Ambulatory assessment to study mobility and activity patterns in healthy aging research(11/2016) Bereuter, Pia; Robert Weibel04B - Beitrag Konferenzschrift
