In the “explore” section, when I search for some taxa in say Italy or Germany , a bounding box is created around the maximum extent of the countries borders. Doing the same thing for Portugal or Austria results in the actual borders being the searched area. This leads to croatian observations showing up in the “Italy” search results, because Croatia falls into the Italy bbox.
Shapefiles for country borders are obviously there (otherwise the max. extents wouldn’t be known), so I’m curious as to why, and with what rule, it is decided, which countries get to have their borders as a searched area, and which get a bbox.
