JEQL is a scripting language for spatial processing and ETL, which runs on the JVM.

JEQL is based on the standard and well-known SQL model. This enables declarative specification of data query and transformation.

JEQL improves on SQL syntax & semantics by adding:

• a streaming model of computation
• factoring of complex SQL queries into a chain of simpler queries
• factoring out and naming common subexpressions
• adding SPLIT BY as the the inverse of GROUP BY

JEQL provides an extensive set of commands and functions.

Built-in commands include:

• Readers and Writers for many textual and spatial formats

Built-in function libraries include:

• geometry manipulation
• String manipulation
• RegEX matching and extracting
