Our lab head Dr René Westerholt discussed the genesis and curation of geographical knowledge in a talk at the conference "Wissen ordnen und entgrenzen" of the Leibniz Institute of European History in Mainz. The presentation placed a special focus on space concepts in the course of the ongoing digital revolution. In this context, the topic of user-generated geodata was discussed in particular, which represents a significant paradigm shift for the spatial knowledge architectures of the 21st century way beyond mere technological evolution. This lecture took place in tandem with historian Dr Monika Barget (Maastricht University), who contrasted the contemporary perspective discussed by Dr Westerholt with the perspective of the early modern period.

In a second invited lecture, Dr Westerholt discussed the tension between the methodological field of statistical spatial analysis and the context of the digital era. This talk, held at the Urban Big Data Centre at the University of Glasgow, made particular reference to the multitude of novel datasets that emerge from everyday practices and have different characteristics compared to traditional scientific datasets. Examples include data from social media, blog posts with spatial location and language, and data from fitness applications. Spatial statistical methods are designed for scientific data collected according to well-defined criteria. Thus, novel problems arise when these established methods are to be applied to the aforementioned novel datasets nonetheless. In this talk, Dr Westerholt offered an overview of two of his recent papers (see references below) in addition to explaining the context of digital spatial concepts. The slides of the lecture are available online: https://www.ubdc.ac.uk/media/2366/presentation-rene-westerholt-290322.pdf.

Location & approach
The campus of TU Dortmund University is located close to interstate junction Dortmund West, where the Sauerlandlinie A 45 (Frankfurt-Dortmund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dortmund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dortmund-Dorstfeld" (closer to Campus Nord). Signs for the university are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dortmund.
To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.
TU Dortmund University has its own train station ("Dortmund Universität"). From there, suburban trains (S-Bahn) leave for Dortmund main station ("Dortmund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The university is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.
You can also take the bus or subway train from Dortmund city to the university: From Dortmund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dortmund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dortmund main station to the stop "Dortmund Kampstraße". From there, take U43 or U44 to the stop "Dortmund Wittener Straße". Switch to bus line 447 and get off at "Dortmund Universität S".
The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.
The H-Bahn is one of the hallmarks of TU Dortmund University. There are two stations on Campus Nord. One ("Dortmund Universität S") is directly located at the suburban train stop, which connects the university directly with the city of Dortmund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.
