Paleogeographic maps are important spatiotemporal visualization tools for revealing geological processes such as surface evolution, plate tectonics, and species distribution, as well as for environmental resource studies and the construction of the Deep-time Digital Earth (DDE). Since the 1970s, international scholars have developed paleogeographic reconstruction models based on large volumes of geophysical data (mainly paleomagnetic data), geochronological data, and fossil data. After more than two decades of research, nearly 30 types of online paleogeographic maps have been published on platforms like EarthByte and the GPlates Web Portal, integrating information such as topography, geological maps, elevation data, magnetic anomalies, and lithology. In China, while many online geological information systems display data such as samples and fossils on modern maps, most systems lack the functionality for online paleogeographic map visualization. This limitation hinders the clear representation of geological data in spatiotemporal dimensions. This system aims to create a single-page web application (SPA) entirely based on open-source frameworks that enables rapid deployment of paleogeographic visualization. Users can switch between various paleogeographic reconstruction models and display geochemical and paleontological data points within a single page. The system adopts Vue components to achieve a clear separation of front-end modules from data, facilitating integration with Web GIS systems for data transmission and functional module consolidation. As a result, it can be quickly integrated into browser/server (B/S) architecture-based geological information systems.
