“Paleo Web GIS” is a Ukrainian web platform for storing and managing paleogeographical (paleoecological) data about modern and ancient soils (including sediments) from the Quaternary period (2.5 million years ago to the present). The main idea behind this Web GIS is to maintain comprehensive information about soil sites in a well-structured format that is available for complex queries. Different sources of information and data formats necessitate a unified database structure, not only to store attributes but also to visualize the spatial distribution of studied objects and research areas. A crucial feature of such systems, given the current circumstances, is the ability to manage content independently by multiple users simultaneously.
