My Urban Memory

Spatial analysis – the city’s memory

Movements in the administrative district of Detmold in terms of commercial areas and historical structures

A project of Lena Sievers – Module „My Urban Memory, Chair „Digital Media und Design“

We are moving on infrastructure, by doing so, we continue its history. Some connecting axises are hundreds of years old. However, by building and adapting new buildings, by building new road networks the history becomes more and more blurry. New motion paths were being recorded through the use of a tracking app. These new motions paths, along with further historical maps, served as a basis to showcase what historical paths and places are still being used and visited.

Research occasion

How can these changes of the settlement structures and the road networks effectively be illustrated in ordert o showcase how they changed within the last 200 years? What roads are still being used today and what places have stayed the same or have grown? What places are now being used for manufacturing? How can data answer these questions through the tracking app?

Approach

The data has been prepared via QGIS in order to select the relevant data foundations. By doing so, structures like main axises, settlement surpluses and industrial parks have been used. As a next step, we overlaped connecting axises with tracking data in order to calculate the overlap. The result were data sets that have been brought together for the JavaScript Library Cesium.js. This way, it is possible to get a visual display via time layers.

New findings

The threedimensional map showchases which structuers are being used until today. Simultaneously, it can be viewed which structures have changed or have vanished entirely. By doing so, it can be estimated what ways played a superior role. Also, it shows that the places where the important axises are lying are the same places where industrial parks popped up.
