map

brief

I focused on traces of traces. On urban interventions and natural processes, traces that have been removed or disappeared over time, leaving new traces behind. Painted-over graffiti, scraped-off stickers, walls with marks of climbing plants.

Using Procreate and Photoshop, I reconstructed these erased traces, making them visible again. I deliberately chose to vary between forensic reconstruction and speculative fiction. Some restorations are intentionally 'wrong'. This playful inaccuracy exposes the difficulty of objective reconstruction and the inherently vague nature of traces. It also questions who controls urban narratives: whose traces are preserved, whose erased?

The interactive map documents my research process itself as a trace. GPS metadata reveals my path through the city and lets the user compare present state and speculative past.

idea

The idea of restoring traces came while I was walking around the city to do research and collect traces for the assignment. Many traces like graffiti and trash are unwanted and get removed, but this act itself often leaves a new trace behind. This caught my eye and I wanted to explore this further by reconstructing erased traces.

process

01. BRAINSTORMING thumbnail
01. BRAINSTORMINGWrote down everything that came to mind when thinking about traces. Looked up definition, origin and synonyms of the word to get more ideas.
02. RESEARCH thumbnail
02. RESEARCHWent out into the city to find traces and researched further into the topic to make sure I didn't miss any important angles during brainstorming. Collected all inspiration on a moodboard.
03. CONCEPT thumbnail
03. CONCEPTI wanted to work with traces that have been removed or faded over time, so I came up with a concept that would allow me to work with traces in a creative way by reconstructing them.
04. COLLECT AND RECONSTRUCT thumbnail
04. COLLECT AND RECONSTRUCTI went out into the city again to find more traces, giving me a diverse set of traces to work with. I then used Procreate and Photoshop to reconstruct the traces.
05. INTERACTIVE MAP thumbnail
05. INTERACTIVE MAPAfter I had all assets, I created an interactive map with Leaflet and used the EXIF data of the images to place them.
