Digital History Workshop: Maps-as-Data: Analysing Historical Maps with Computer Vision

27 February 2020
12:00 - 14.45

Daniel van Strien (British Library) and Kaspar von Beelen (The Alan Turing Institute)

A growing challenge for digital historians is the diversification of their sources. Traditionally, these included tabular and textual data, but in recent years the analysis of visual collections has gained prominence as well. In this workshop, we introduce you to the basic principles of visual analytics and its application to humanities research. In particular, we show how to apply computer vision to historical maps. Maps serve as a rich resource for historical inquiry, but until very recently, they remained difficult to examine digitally--unless they came as georeferenced and manually vectorized data sets. We demonstrate, however, how computer vision now enables researchers to analyse spatial data in ways that are efficient, scaleable and considerably less resource-intensive. 
We zoom in on specific elements of the computer vision pipeline such as transfer learning, image augmentation and other techniques, all which greatly facilitate the analysis of historical maps at scale. The hands-on part of the workshop will cover useful and practical methods for research and curation, including; classifying images automatically (including methods for automating some of the quality assurance steps of digitisation work), understanding maps-as-data, Working with large and small (<200) collections of images; evaluating a classification model and assess its performance: How well it is working? Or is it the wrong tool for the task at hand?  

This tutorial will focus primarily on using Ordance Survey maps (digitized by the National Library of Scotland) but many of the techniques we cover can be adapted to other types of visual material such as photographs, art collections, or satellite imagery. The workshop is open to everyone: no coding skills are required, but please bring your own laptop.


Salon: Source Criticism and History Teaching in the Age of the Digital Archive

27 February 2020

Source Criticism in the Era of the Digital Archive

Kaspar von Beelen (The Alan Turing Institute) 
Source criticism is central to the historian's interpretation of the past: it applies common-sense scepticism to the sources, not only seeking forms of deliberate deception, but also the subtle biases playing out in the corpus. Historians explain by critically contextualising their information, close reading their sources, mostly a limited number of documents. The question then arises: how to critically read and investigate digital archives, sometimes containing millions of documents? How to combine "distant reading" with source criticism? In this presentation we introduce the idea of the "environmental scan", a method for contextualising digital collections, and facilitating source criticism at scale by providing methods that simultaneously exposes the limits, biases and gaps of an archive.

Claartje Rasterhoff (Boekmanstichting; UvA)
Claartje Rasterhoff will talk about how she used historical data and digital mapping in her teaching at UvA. She will share some thoughts on how to (not) teach digital methods in a history program and showcase several student projects.
