Animal Movement Cleaner Application : un outil de pré-traitement des données de biologging

Abstract : Bio-logging consists in using miniaturised tags to uncover animals’ hidden lives. It gives access to former unreachable data. Resulting data are usually welcomed with eagerness, but caution should also be added. Indeed, Raw data may contain outliers which could skew analysis if kept. Hence, the present dissertation deals with the development of a pre-treatment tool for those datasets. First of all, outliers’ origins have been described depending on the geolocation technology. After that, a need analysis led to the conclusion that a new tool doing automated pre-treatment to remove outliers would only be useful if it is easy to use and if the user has the final word. The tool must also work for any species, any geolocation technology and any dataset structure. Those parameters have been considered during AMCA, Animal Movement Cleaner Application, development. It is a web application which purpose is to eliminate impossible data and data with out-of-range speed. It is also able to detect immobility. Currently, AMCA is working for GPS technology and Movebank data structure. Easy to use, it also enables users to modify algorithms-kept and eliminated data thanks to a 3D visualization.
