SYNTHESIS: THE ONLINE TOOL PROVIDING EASY ACCESS AND SYSTEMATIC CROSS-CHECKING OF ALL USEFUL INFORMATION FOR AVALANCHE DANGER ASSESSMENT
Résumé
Having a clear vision of current and future snow and avalanche situation depends on a limited number of criteria widely accepted in our community. According whether it is carried out by a forecaster or a practitioner, this task nevertheless requires a significant amount of information to be cross-checked. Due to either lack of time or negligence, such a cross-checking is not systematically carried out. Here again, human factors sometimes prevail over common sense. The originality of our approach lies in the stated wish to make rational use of digital tools to automatize this task, or at least simplify it. For this reason, we have developed the SYNTHESIS tool, accessible via the www.data-avalanche.org platform. On the one hand, it provides an innovative graphical representation that overlays recent avalanche observations, snow tests results, the positions of automatic measuring stations, the danger level, and the critical slope aspects from official bulletins. On the other hand, SYNTHESIS, as suggested by the name, brings together in a single place all useful information available online: avalanche danger bulletins, slope gradients map, descriptions of recent avalanche observations as well as the map of avalanche areas' history, data from automatic measuring stations, and finally snow tests graphical representations. Such information corresponds to the six criteria of the CRISTAL approach. The objective of SYNTHESIS is not to produce an automatic avalanche danger assessment, but to simplify as much as possible data retrieving and exploitation tasks.
