Workflow
The following chart illustrates the workflow of this project, including sources of data, software/tools used in the analysis, storage locations of the produced research data and the output generated by us.
Sources
Literature Research: The starting point for building an inventory to use for this project were two books on Max Vogt: Max Vogt – Bauen für die Bahn 1957–1989 by Ruedi Weidmann and Karl Holenstein (2008), and the SBB Bauten Max Vogt photo book by Martin Stollenwerk (2006). Both present catalogues of works by Max Vogt, although they differ quite substantially. With this data, we built a combined inventory, drawing on additional sources such as cantonal/communal heritage convervation inventories for Zurich (2020), news reports or articles in architecture journals (e.g. Allenspach 1994; Odermatt 1974) or internal SBB newspapers (e.g. Bolliger 1977; Generaldirektion SBB 1978, 1979b). For a full list of references, see the Zotero collection or refer to the individual object bibliographies in the maxvogt online collection.
Federal Register of Buildings and Dwellings: The data collected from the literature research was augmented with selected statistics on individual buildings that is available in the federal building registry (Eidgenössisches Wohnungs- und Gebäuderegister, GWR). Especially relevant for us is the information on building construction years, even though there are several deviations of more than a decade compared to other sources. Refer to the Merkmalskatalog for more information on this resource.
Field Survey: All items that are part of the maxvogt collection were visited in spring/summer 2024 for photo documentation and a survey of building features resp. spatial context. In a few cases where the address of a building was not provided in the sources, the locations could be determined via satellite imagery (e.g. the service building in Landquart). Apart from taking photos, the authors collected information that was later put into the OpenStreetMap database.
SBB Historic Archives: A lot of sources on Max Vogt’s buildings are available in SBB Historic’s archive. The catalogue was screened for content that was deemed to be relevant for the collection items. Some of SBB Historic content is also available on Wikimedia Commons, but mostly the online catalogue points to offline data. Quite a lot of images are available to pre-view online, but it is not possible to download or embed them elsewhere. Noteworthy are the built heritage inventories done around the 1980s by Hans-Peter Bärtschi (e.g. an inventorisation of the station infrastructure in Feldbach SG).
External Web Content was used in several cases for research and to add content to the online collection. Large repositories for potential data are YouTube – especially for historic amateur videos – and photo platforms. Apart from Flickr, more railway-specific platforms such as bahnbilder.de come to mind, even though it turned out that most pictures found there focus on the rolling stock and not on the buildings. A few short news reports on Vogt and his buildings, most of them obituaries on the occasion of Vogt’s death in 2019, can also be found online. Content of this type was mainly used to get more information on e.g. building heights or to determine at what point in time a building was renovated, painted, expanded etc. External web content was either directly added to the CollectionBuilder items or stored in the Zotero project bibliography (see below).
Data Storage
Wikidata: All items that make up the collection of works by Max Vogt were added to Wikidata with a statement specifying Max Vogt as the architect. Display all Wikidata items for buildings by Max Vogt using this query. Max Vogt himself also has a wikidata item: Q1913571. Each built structure has technical information stored in Wikidata, and, where available, information on renovation/restauration timelines. Links to the objects’ Wikimedia Commons Categories and OpenStreetMap entries were established using the corresponding Wikidata properties. Where applicable, reference links are provided for statements. Some secondary literature on Max Vogt is also modelled on Wikidata – refer to the items about Max Vogt using this query.
Wikimedia Commons: As part of the field survey in spring/summer 2024, the authors took photos of each collection item and uploaded a selection of them to Wikimedia Commons with the intention of loading those images into CollectionBuilder. A Commons Category for Max Vogt already existed and was restructured to fit the data model. There are categories for buildings, fountains and bridges by Max Vogt with a total of 112 subcategories – one for each structure designed by Vogt where media is available. All uploaded images were annotated comprehensively, with description texts, technical image metadata, and geocoordinates of object and photography locations. An overview map is available via WikiMap. Image metadata is also available as structured data. Wikimedia Commons category pages are linked to the corresponding Wikidata items to add infoboxes on the category pages. In those cases where relevant files had already been uploaded to Wikimedia Commons before, they were also added to the object’s category. These third-party files are mostly provided by SBB Historic (see above) or ETH Zurich Library’s E-Pics database. As an additional feature, Wikimedia Commons allows users to tag and annotate image regions as in this file. Buildings by Max Vogt were added as notes, linking to the corresponding Wikidata entries. This annotation has only been done for a few singular items so far.
OpenStreetMap: All relevant information gathered during the surveys was added to OpenStreetMap (OSM). All OSM data tagged as items by Max Vogt can be displayed via the Overpass API using this query. Except for two of Vogt’s works, all were already present in the OSM database. Pre-existing data was enriched with more and up-to-date information from the suveys in spring/summer 2024. Several buildings had to be re-mapped by splitting up larger building complexes that had been mapped as one single item. Via the corresponding OSM tagging scheme, links to Wikimedia Commons and to Wikidata were added to the database (and vice versa). Additionally, all buildings were modelled according to the Simple 3D Buidings tagging scheme and are, as of September 2024, available for use in OSM 3D renderers such as the F4Map Demo or Kevin Nowaczyk’s OSM Building renderer. Please note that not all renderers support all features of the Simple 3D Buildings tagging scheme.
GitHub Repository maxvogt: The GitHub repository at mtwente/maxvogt is the technical basis for the online collection about Max Vogt set up by the authors. A detailed description is available in the repository’s readme. The repository contains an instance of CollectionBuilder, an open source framework for creating metadata-driven digital collections which is developed at the University Library of Idaho. Barely any actual research data is stored in the repository, since all collection items (images, PDFs, geodata) are fetched from other sources, such as Wikimedia Commons, SBB Archiv and others.
GitHub Repository maxvogt-analysis: The GitHub repository at mtwente/maxvogt-analysis is used for storing research data that was generated as part of this project. The authors provide project documentation, license information, instructions on how to reproduce the data set using Jupyter Notebooks. Geodata that is generated by running the notebooks is stored in the repository in json files, and is fetched from here to be displayed in the online collection using a Leaflet map. The maxvogt-analysis repository is based on the GitHub template for FAIR and open research data by Moritz Mähr, adhering to best practices for open research data as outlined by The Turing Way.
Zenodo: The authors use Zenodo for long-term archiving of the project data and its output, e.g. for making the project conference poster available in PDF format.
Output
Website maxvogt: One major part of the project is the online collection about Max Vogt’s work. This collection is made with CollectionBuilder (see above), which generates a website for browsing the data set and facilitates explorative access to the collection using features such as timelines, maps and wordclouds. The website is hosted using GitHub Pages and is accessible via https://mtwente.github.io/maxvogt.
Website maxvogt-analysis: The online collection on Max Vogt is partly built with geodata generated by Jupyter notebooks in the maxvogt-analysis repository. The authors built this website to document the project research data. It is built with Quarto, see the section about the maxvogt-analysis GitHub repository above for more information. The website is hosted using GitHub Pages and is accessible via https://mtwente.github.io/maxvogt.
Zotero: The corpus of literature that was consulted for this research project consists of a few academic publications, especially from heritage conservation studies and Swiss architecture guides (e.g. Weidmann and Holenstein 2008; Noseda 1998; Allenspach 1994; Weidmann 2008). Additionally, there are several articles in newspapers or in architecture journals relating to Vogt’s work – either on the occasion of a station’s redesign (e.g. Capol 1998; Cieslik 2020; Hodel 2019; Huber 2022; SBB Immobilien 2023) or as part of obituaries for Vogt (e.g. Vögeli 2019; Salm 2019; Hohler 2019; Redaktion Züriost 2019). Relevant sources for contemporary descriptions of individual buildings are internal SBB documents such as employee newspapers (e.g. Generaldirektion SBB 1979b, 1978, 1979a) and other corporate publications (e.g. SBB Historic 2018; SBB Immobilien 2023). Most of the internal SBB documents are not accessible online. The authors used both SBB Archives or libraries such as the Basel University Business and Economics Library/Swiss Economoic Archives. Sources were added to a shared Zotero library to facilitate access to research on Max Vogt’s work.
Conference Poster: This project was presented at the Spatial Humanities 2024 conference in Bamberg. A poster showcased the project using four selected collection items to exhibit the range of projects that are part of Vogt’s catalogue of works. Additionally, information on Vogt’s biography and on CollectionBuilder is provided. The poster itself was designed using Adobe InDesign, the drawings were made using Adobe Illustrator, and the map was created with OpenStreetMap geodata in QGIS. The poster is archived on Zenodo, see SpatHum 2024 Poster.
Tools
The analysis is split up in Jupyter Notebooks that are available in this repository and can be launched either locally or using Binder.
The most important tool used for the spatial analysis is momepy1 by Martin Fleischmann and James Gaboardi. See the documentation for momepy examples and tutorials.
Geodata used for the analysis is retrieved from OpenStreetMap using the OSMnx2 package by Geoff Boeing. See readthedocs.io for documentation.
