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.  aSpatial data1 aJOÃO, R. S.1 aROMANI, L. A. S.1 aRIBEIRO, M. X.
