René Westerholt gave an invited talk at the International Conference on Geospatial Information Science organised by the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing (LIESMARS) at Wuhan University. The presentation dealt with methodological challenges in the spatial analysis of so-called "ambient geospatial information". The latter includes geographic datasets collected as a by-product of other activities, for example via the use of spatial language in blogposts or via Twitter microblogs tagged with geo-coordinates. In the spatial analysis of these datasets, inconsistently used conceptualisations of the discourse subjects contained in the data, the simultaneity in space and time of different but hard-to-separate phenomena, and other inconsistencies pose a veritable challenge. Many of the challenges mentioned are due to a discrepancy between the space concepts applied in the analysis and those relevant at the time of data production. René Westerholt not only addressed these general problems, but also discussed a paper he published in 2021 that offers a workaround to some of the problems mentioned. The full paper can be found at:
