The paper presents the details of designing and develo** GeoSpark, which extends the
core engine of Apache Spark and SparkSQL to support spatial data types, indexes, and …

Data Visualization allows users to summarize, analyze and reason about data. A map
visualization tool first loads the designated geospatial data, processes the data and then …

The spatial learned index constructs a spatial index by learning the spatial distribution,
which performs a lower cost of storage and query than the spatial indices. The current …

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 …

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 …

Movement is a dynamic process that is increasingly being monitored by a variety of tracking
systems. As a consequence, analysts who are trying to understand movement processes are …

Although spatial indexes shorten the query response time, they rely on complex tree
structures to narrow down the search space. Such structures in turn yield additional storage …

The growing diffusion of the latest information and communication technologies in different
contexts allowed the constitution of enormous sensing networks that form the underlying …
