The EBP demo viewer aims at showing the scope and potential of the EBP project and its future developments. It is, therefore, solely a very first insight about the possibilities of the collaborative work of European on-line bird recording schemes under the auspices of the EBCC.
The EBP demo viewer shows animated maps depicting the week-by-week distributional patterns of 100 species in six years (2010-2015) at a resolution of 30x30 km. A total of five types of species maps and four of climatic variables are shown. Two animated maps of any species or climatic variable, year and type can be selected to be shown simultaneously for direct comparison.
Moreover, the option "All years", in the year dropdown list, allows the visualization of the overall seasonal patterns of bird distribution and the climatic variables averaged across the different years of available data. All in all, therefore, more than 20.6 million different map combinations are available to choose from.
Note that you can either select natural years (for example “2014”) or July to June interannual cycles (for example “2014/15”). In the latter, the time series starts at week number 27 of the first year (2–8 July), and finishes in week number 26 of the following year (25 June – 1 July). When selecting natural years the time series starts in week number 1 (1–7 January) and finishes in week number 52 (26–30 December).
