In the last decade, geospatial data which is extracted from GPS traces and satellites image has become ubiquitous. GeoVisual analytics, abbr. GeoViz, is the science of analytical reasoning assisted by geospatial map interfaces. GeoViz involves two …
In this paper, we demonstrate Tabula, a middleware that sits between the data system and the geospatial visualization dashboard to increase user interactivity. The proposed system adopts a sampling cube approach that stores prematerialized spatial …
—In this paper, we present a middleware framework that runs on top of a SQL data system with the purpose of increasing the interactivity of geospatial visualization dashboards. The proposed system adopts a sampling cube approach that stores …

Visualizing data on maps is deemed a powerful tool for data scientists to make sense of geospatial data. The geospatial map visualization (abbr. MapViz) process first loads the designated geospatial data, processes the data and then applies the map …
Data Visualization allows users to summarize, analyze and reason about data. A map visualization tool frst loads the designated geospatial data, processes the data and then applies the map visualization efect. Guaranteeing detailed and accurate …
The paper presents Babylon a large-scale Geospatial Visual analytics (GeoViz) system that performs the spatial data preparation and map visualization phases in the same distributed cluster.
