SalienTime: User-driven Selection of Salient Time Steps for Large-Scale Geospatial Data Visualization

arXiv:2403.03449v1 Announce Type: cross
Abstract: The voluminous nature of geospatial temporal data from physical monitors and simulation models poses challenges to efficient data access, often resulting in cumbersome temporal selection experiences in web-based data portals. Thus, selecting a subset of time steps for prioritized visualization and pre-loading is highly desirable. Addressing this issue, this paper establishes a multifaceted definition of salient time steps via extensive need-finding studies with domain experts to understand their workflows. Building on this, we propose a …
