> ST_Within uses wrong JTS Function
> ---------------------------------
>
> Key: SEDONA-118
> URL: https://issues.apache.org/jira/browse/SEDONA-118
> Project: Apache Sedona
> Issue Type: Bug
> Affects Versions: 1.2.1
> Reporter: Dimitris Bilidas
> Priority: Minor
>
> The eval method of ST_Within (in file Predicates.scala) calls the function
> coveredBy of JTS. Instead, it should call the within function.
> As a result, now, the expression
> {code:java}
> ST_Within(ST_GeomFromWKT('POINT(0 0)'),ST_GeomFromWKT('POLYGON ((0.0 0.0,
> 10.0 0.0, 10.0 10.0, 0.0 10.0, 0.0 0.0))')) {code}
> returns true, whereas the correct behaviour according to the simple features
> specification for sql should be false.
> Also, the toString method of the ST_Within is wrong.
