Abstract：Based on Spark distributed computing model and Geohash spatial encoding,this paper proposes a multi-level time encoding,and designs an algorithm and system for efficiently calculating the density distribution of massive ship targets. Taking the AIS ship target data of the Bohai Bay area in 2016 as an example,it is proved that the system can calculate the density distribution quickly and efficiently in a large space and time range.
