  • Using volunteered geographical information to map the November 2012 floods in Slovenia
    Triglav Čekada, Mihaela ; Radovan, Dalibor
    Volunteered geographical information represents a promising field in the monitoring and mapping of natural disasters. The contributors of volunteered geographical information have the advantage that ... they are at the location of the natural disaster at exactly 5 the time when the disaster happened. Therefore, they can provide the most complete account of the extent of the damage. This is not always possible when applying photogrammetric or remote-sensing methods, as prior to the data acquisition an order to carry out the measurements has to be made. On 5 and 6 November 2012 almost half of Slovenia was badly affected by floods. The gathering of volunteered geographical information in the form of images and videos of these floods will be presented. Two strategies were used: (1) a public call for volunteered contributions and (2) a web search for useful images and their authors. The authorship of these images was verified with every contributor, and with the help of the volunteered images 12% of the most severely affected river sections were mapped. Altogether, 1195.3 ha of flooded 15 areas outside of the usual riverbeds along a total river length of 48 km were mapped. The results are compared with those from satellite mapping of the same floods.
