GEOGRAPHICAL MAP-BASED VISUALIZATION OF BIG DATA

摘要

A method of geographical map-based visualization of big data, comprising : performing a random sampling of a dataset to obtain a sample representative of the dataset (610); dividing the sample into a plurality of partitions (620); clustering each partition of the plurality of partitions to provide a plurality of data blocks each of which comprising a respective plurality of data items (630); extracting respective one or more representative points from each data block of the plurality of data blocks to represent the respective data block (640); displaying the respective one or more representative points for each of the data blocks (650).
