Wiki Maps

The Nnistar Map on June 18, 2011

Le mappe wiki sono compilate a partire dai dati delle misurazioni disponibili su internet.
Si caratterizzano per il fatto di essere realizzate in modo partecipativo con contributi diversi, che possono essere di scienziati, funzionari di istituzioni varie e utenti comuni (maggiori informazioni sul significato di wiki).

Il vantaggio dell’approccio wiki è che si possono ottenere mappature complesse e molto dettagliate in tempi molto brevi.

Nel caso della misurazione della radioattività, lo svantaggio è che alcuni dei dati di provenienza possono avere qualche margine d’incertezza. Tuttavia queste mappe sono indicative della tendenza generale del grado di contaminazione radiologica e sono un buon complemento delle mappe ufficiali.

  • New Safecast Global Map

    Wiki map of radioactive contamination. Source: Safecast)

    Navigable map of radioactive contamination compiled by visualization team at MIT in Cambridge lead by Anthony DeVincenzi. The map is based on data from over 2,000,000 measurements taken in Japan by collaborators of Safecast, a global wiki project to build a network of sensors and data of the radioactivity.
    The measures are expressed in microSieverts per hour (μSv/h).

  • Japan Geigermap
    In the wake of Japan’s Fukushima disaster, amidst a climate of general mistrust of government radiation data, a number of crowdsourced initiatives for mapping radiation levels sprang up, such as Japan Geigermap, in which radiation readings from citizens are aggregated and displayed online using a web service called Pachube.

  • Radiation dose measured in Japan

    Radiation dose measured in Japan. Google map compiled by Nnistar, data MEXT, Nov. 27, 2011

    Google map compiled by Nnistar with survey data of ground radiation dose measured by local governments between 0.5 and 1 meter height, and published by Ministry of Education, Culture, Sports, Science and Technology of Japan (MEXT) since April 2011. Some of the data source can have a degree of uncertainty, but the map present the general trend of the degree of radiological contamination (see more in the review by Backyard World).
    The data are updated to november 27, 2011, the measures are expressed in microSieverts per hour (μSv/h).
