------------------------------------
Summary: Use JTS rather than ESRI as the underlying library for
geospatial (ST_) functions
Key: CALCITE-4294
URL: https://issues.apache.org/jira/browse/CALCITE-4294
Project: Calcite
Issue Type: Bug
Components: spatial
Reporter: Julian Hyde
The geospatial functions are currently implemented using the ESRI library. We
should consider using JTS instead. AT the time we started work on geospatial
the JTS did not have a suitable license, but this is no longer the case. I
gather that JTS is a superior library.
