One year after the public launch of the mobile application, we carry out a self-critical evaluation of the experience with regard to the requirements of a sustainable and effective ecological surveillance tool. We first demonstrate the attractiveness of the developed multimedia system (with more than 90K end-users) and the nice self-improving capacities of the whole collaborative workflow. We then point out the current limitations of the approach towards producing timely and accurate distribution maps of plants at a very large scale. We discuss in particular two main issues: the bias and the incompleteness of the produced data. We finally open new perspectives and describe upcoming realizations towards bridging these gaps. specialized 122 076 Spampinato C. ed. edt IRD Mezaris V. e. aut IRD Van Ossenbruggen J. ed. edt IRD 22 6 (no spécial) 751-766 2016 0942-4962 https://www.documentation.ird.fr/hor/fdi:010068289 10.1007/s00530-015-0462-9 0942-4962 [F B010068289] https://www.documentation.ird.fr/hor/fdi:010068289 https://www.documentation.ird.fr/intranet/publi/2016/11/010068289.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-12-06 2020-06-17 fdi:010068289 fre
