[jira] [Created] (CALCITE-4294) Use JTS rather than ESRI as the underlying library for geospatial (ST_) functions

Julian Hyde created CALCITE-4294:
------------------------------------

             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.
