Mapping Geotagged Photos in Public Spaces

For any city, thousands of geotagged photos are available online. This  project by Philipp Schmitt maps these photos in the places where they were taken.

A custom-built camera flash + smartphone setup queries the Flickr and Panoramio APIs for photos taken at the current geographical position. Whenever there’s a photo available, a flash is triggered. Long-exposure photography captures multiple flash lights — each representing one geotagged photo — and situates them in the place of their origin.

This is a visual representation of pollen concentration in the air of Barcelona.

Each concentric ellipse represents a plant, from outer to inner: Cupressceae, Corylus, Pinus, Platanus, Parietaria, Quercus, Palmae, Poaceae, Plantago, Chenop.-Amaranth, Asteraceae, Artemisa.

Each 1/12 section of the circle represents a month, and each month is divided into four weeks, so it’s not an accurate representation of the original data wich has 52 weeks instead of 48.

The size of the dots equals the density of the pollen concentration in a scale from 1 to 4 and each inner plant is a 10% smaller in size than the outer one. So a concentration of Artemisa pollen of 4 would be a eleven times 10% smaller than a concentration of 4 from a Cupressceae (5 mm and 1,57 mm).

I’m not good at math so excuse the possible mistakes in the explanation.
