This section describes the Spark jobs and Hive user defined functions (UDFs) for geometry and coordinate operations and the ability to read TAB files.

Spark jobs use the Location Intelligence SDK (LI SDK) API in map and reduce operations to use the big data processing systems for spatial data analysis. The LI SDK provides geometry and coordinate operations, the ability to read TAB files, and in-memory r-tree creation and searching.

Hive UDFs also use the LI SDK API to provide SQL-like functions for spatial analysis in Hive.
