----------------------------------------
Summary: Support spatial predicates other than INTERSECTS and
COVERS/COVERED_BY in RangeQuery.SpatialRangeQuery and JoinQuery.SpatialJoinQuery
Key: SEDONA-177
URL: https://issues.apache.org/jira/browse/SEDONA-177
Project: Apache Sedona
Issue Type: Improvement
Reporter: Kristin Cowalcijk
This is an RDD API improvement which will be helpful for fixing SEDONA-119. The
major changes are:
*Spatial Predicates*:
We've defined 9 commonly used spatial predicates in {{enum SpatialPredicate}}:
{code:java}
public enum SpatialPredicate {
CONTAINS,
INTERSECTS,
WITHIN,
COVERS,
COVERED_BY,
TOUCHES,
OVERLAPS,
CROSSES,
EQUALS
}
{code}
*Spatial Range Query*:
User can specify one of the spatial predicates in RangeQuery.SpatialRangeQuery.
{code:java}
val rangeQueryWindow = new Envelope(-90.01, -80.01, 30.01, 40.01)
val usingIndex = false
var queryResult = RangeQuery.SpatialRangeQuery(spatialRDD, rangeQueryWindow,
SpatialPredicate.COVERED_BY, usingIndex)
// this is equivalent to
// RangeQuery.SpatialRangeQuery(rangeQueryWindow, spatialRDD,
SpatialPredicate.COVERS, usingIndex)
// or
// val considerBoundaryIntersection = false
// RangeQuery.SpatialRangeQuery(spatialRDD, rangeQueryWindow,
considerBoundaryIntersection, usingIndex)
{code}
*Spatial Join Query*:
User can specify one of the spatial predicates in JoinQuery.SpatialJoinQuery.
{code:java}
val usingIndex = false
var result = JoinQuery.SpatialJoinQuery(objectRDD, queryWindowRDD, usingIndex,
SpatialPredicate.COVERS)
// this is equivalent to
// val considerBoundaryIntersection = false
// JoinQuery.SpatialJoinQuery(objectRDD, queryWindowRDD, usingIndex,
considerBoundaryIntersection)
var result = JoinQuery.SpatialJoinQuery(objectRDD, queryWindowRDD, usingIndex,
SpatialPredicate.INTERSECTS)
// this is equivalent to
// val considerBoundaryIntersection = true
// JoinQuery.SpatialJoinQuery(objectRDD, queryWindowRDD, usingIndex,
considerBoundaryIntersection)
{code}
