During WW2, the National Socialists established detailed assessments of, and plans for, the whole region of Eastern Europe. This volume presents the findings of research into the stakeholders, practices and techniques deployed in architecture, spatial and urban planning. In particular, it scrutinizes the 'measurablility' of the Nazi occupation regime and the options available in terms of documentation and presentation with digital analytical tools. These tools provide a qualitative extension of the current state of knowledge; in addition, quantitative criteria are subjected to computer aided analyses that offer substantiation to statements that are both wide-ranging and well supported. The volume explores the extent to which the Digital Humanities propose new and innovative techniques with which architectural historians can re-assess the aims and practices of the Nazi regime in Eastern Europe.
