This study uses data from smartphone accelerometers and a k-means++ algorithm to determine the quality of road sections. This is easy and cost-effective to apply to large-scale cycling networks and shows in a case study for the city of Salzburg that poorly passable lane sections can be well localised and subsequently maintained in a targeted manner.","PeriodicalId":36308,"journal":{"name":"AGIT- Journal fur Angewandte Geoinformatik","volume":"1 1","pages":"104-116"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75958135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These sensors are primarily designed to internally control miscellaneous comfort and safety functions but are also offering potential to be used externally in cross-sectoral applications, such as water management use cases. At this point, the general suitability of vehicle sensor data for realtime agglomeration of precipitation information using the example of Emscher and Lippe region is one of the key issues of the research project mobileVIEW. A major challenge in implementation in order to be able to conduct spatio-temporal adjustments of precipitation data is to derive valid precipitation values from vehicle sensor measurements. For this purpose, a decision tree trained with historical precipitation radar data is used to derive precipitation intensities from a combination of rain related measurements with additional environmental values based on the position of the vehicle. Emerging potential for runoff forecasting and heavy rainfall nowcasting is analysed within the operational flood early warning system based on Delft-FEWS.","PeriodicalId":36308,"journal":{"name":"AGIT- Journal fur Angewandte Geoinformatik","volume":"173 ","pages":"274-279"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72419429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Full reconstruction as a 3D-model becomes increasingly time-consuming, while volumetric scanning is prone to scanning artefacts.

In addition to the basics of capture and presentation of these panoramas, we discuss how to include further multimedia content and how to guide user navigation. To ensure a high level of accessibility, we utilize current web technologies.","PeriodicalId":36308,"journal":{"name":"AGIT- Journal fur Angewandte Geoinformatik","volume":"05 1","pages":"161-171"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80130400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3D basemap is the basis for different 3D map applications and can be used for overlays, analyzes or for realistic mapping of the entire environment. However, many of the available basemaps are currently available in 2D only. In this article, we present strategies for converting the freely available basemap.at from 2D to 3D. Therefore, the technical implementation and some design decisions for the digital terrain model (DTM), point data, line data and polygon data are described in more detail. As the result, we present two first prototypical implementations of basemap.at-3D – one in a simplified/schematic version and one in a more realistic version of a 3D basemap.","PeriodicalId":36308,"journal":{"name":"AGIT- Journal fur Angewandte Geoinformatik","volume":"8 1","pages":"132-145"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76796483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
