KEY WORDS: ClickHouse, vector spatial data, query processing, HBase, remote sensing. ... When querying a spatial range using the georadius method, it transforms the query of two-dimensional space into the comparison of strings of one-dimensional space, which makes it highly efficient for spatial range queries (Liu et al., 2014). (Hao Yu et al ...
