Interactive toponymical map presented here shows 2332 inhabited places of Lithuania that have names (oikonyms) associated with vegetation and animals. The map and the dataset are the
outcomes of a project that is aimed at combining the outcomes of professional onomastic research with popular presentation and an environment that fosters exploration. The oikonyms were extracted from the reference base dataset of Lithuania by means of an automated algorithm created for that purpose. Original cartographic signs have been designed for depicting categories and
species. The multiscale map application, makes it easy to see spatial distribution of geographic names related with particular groups of plants and animals. Analysis of map data enables the assertion that local toponymy reflects a distribution of species that were characteristic to the territory over past centuries. The maps are supplemented by comparative density maps and statistical charts. The reference scale of the main maps is 1: 500,000.
