Kristin Cowalcijk created SEDONA-176:
----------------------------------------

             Summary: Make ST_Contains conform with OGC standard, and add 
ST_Covers and ST_CoveredBy functions.
                 Key: SEDONA-176
                 URL: https://issues.apache.org/jira/browse/SEDONA-176
             Project: Apache Sedona
          Issue Type: Improvement
            Reporter: Kristin Cowalcijk
             Fix For: 1.3.0


The semantics of {{ST_Contains}} is actually "covers" defined by OGC, and 
{{ST_Within}} used to be "coveredBy" but changed to "within" after resolving 
SEDONA-118. We'll change the semantics of {{ST_Contains}} to "contains" and add 
additional UDFs  {{ST_Covers}} and {{ST_CoveredBy.}}
