Conteúdo: | Analyzing and understanding spatial data that vary over time is a complex task. Usually, the data is arranged in a tabular or text forms. We develop the ST-Vis (SpatioTemporal Visualization) tool to provide a visual representation of spatiotemporal data, which must help users to understand a temporal variation in a region when combining the parallel coordinates graph with a geographic map, a temporal texture, and a table. The temporal texture maps the linear form of the variation of the Normalized Difference Vegetation Index (NDVI), resulting in a representation of colors texture, and each texture cell refers to a period. ST-Vis provides a simultaneous spatiotemporal representation of data, and the visualizations interact with each other through animations. We evaluated ST-Vis by interviewing some domain experts, computer science, and other field students, who experienced ST-Vis tool. The results show that ST-Vis allows the understanding of spatiotemporal data through the generated visualizations. This tool simultaneously displays visualizations, which have interactions with each other through animations.
