OpenStreetMap (OSM), based on collaborative mapping, has become a subject of great interest to the academic community, resulting in a considerable body of literature produced by many researchers. In this paper, we use Latent Semantic Analysis (LSA) to help identify the emerging research trends in OSM. An extensive corpus of 485 academic abstracts of papers published during the period 2007–2016 ...

High-quality geographic data sources are eminent for urban data management and the creation of detailed 3D city models. In the last two decades, Volunteered Geographic Information (VGI) increasingly gained attractiveness to both amateur users and professionals, resulting in a broad availability of urban data within VGI communities and especially OpenStreetMap (OSM). OSM provides detailed inform...

Street names provide important insights into the local culture, history, and politics of places. Linked open data provide a wealth of knowledge that can be associated with street names, enabling novel ways to explore cultural geographies. This paper presents a three-fold contribution. We present (1) a technique to establish a correspondence between street names and the entities that they refer ...

Being subject of historic growth and focusing on the load supply in the past, only few low voltage grid models are available for research purposes. Due to energy system changes with large amounts of renewable feed-in being redistributed within these grids, it becomes more important to create a reliable data basis to evaluate innovative control approaches. Facing this lack of data, in this paper...

A new pedestrian GPS navigator providing the shortest-cost safest-crossing route on the basis of Open Street Map (OSM) cartographic data is proposed. Also, Java implementation and use case example are discussed.

We present a method for calculating phase diagrams for the high dimensional variant of the Self Organizing Map SOM The method requires only an ansatz for the tesselation of the data space induced by the map not for the explicit state of the map Using this method we analyze two recently proposed models for the development of orientation and ocular dominance column maps The phase transition condi...

Finding the way in known and unknown city environments is a task that all pedestrians carry out regularly. Current technology allows the use of smart devices as aids that can give automatic verbal route directions on the basis of the pedestrian’s current position. Many such systems only give route directions, but are unable to interact with the user to answer clarifications or understand other ...

There is a relationship between what we say and where we say it. Word embeddings are usually trained assuming that semantically-similar words occur within the same textual contexts. We investigate the extent to which semantically-similar words occur within the same geospatial contexts. We enrich a corpus of geolocated Twitter posts with physical data derived from Google Places and OpenStreetMap...

Online services such as Google Maps or Open Street Maps allow the exploration of maps on smartphones and tablets. The gestures used are the pinch to adjust the zoom level and the drag to move the map. In this paper, two new gestures to adjust the zoom level of maps are presented. Both gestures – with slight differences – allow the identification of a target area to zoom, which is enlarged autom...
