A geometry‐based method for visualizing time‐varying flow fields on web map platforms using texture polymorphism

Global climate change has escalated flood risks, necessitating advanced hydrodynamic models for predicting watershed dynamics. Integrating flow‐field visualization with web maps offers a time‐sensitive, geographic context for sharing and understanding these dynamic changes virtually. Traditional methods use texture series on maps for flow visualization but fall short in interactive detail examination. Drawing geometric shapes directly on maps has been limited by low efficiency. Addressing the need for interactive visualization and efficiency, this study presents a texture polymorphism strategy for geometric visualization of time‐varying flow fields. This approach combines geometric style simulation with texture‐assisted computation, optimizing interactivity and performance on web map platforms. Our evaluation confirms that this method enhances usability and integration, ensuring high performance in visualizing flow dynamics.
