Fwd: JoinQueryRaw.SpatialJoinQueryFlat for polygon - linestring join?

[Jia Yu]

And please try to switch the left and right side of the join and see if the
result changes.

JoinQuery.SpatialJoingQueryFlat(RddA, RddB, considerBoundaryIntersection)
means that check if each one in Rdd A is CONTAINED BY each one in Rdd B,
considering the situation of boundary intersecting (not fully contained).

In your case, a line cannot contain a polygon, but a polygon can contain a
line. Make sure you get the order correct.

Thanks,
Jia

Hi Mark,

Sedona supports polygon-linestring joins. Did you set
'ConsiderBoundaryIntersection' to true? See:
https://sedona.apache.org/1.3.1-incubating/tutorial/core-python/#write-a-spatial-join-query

This is the last parameter in Sedona Python
JoinQueryRaw.SpatialJoinQueryFlat().

Thanks,
Jia

Hi all,

I am trying to use JoinQueryRaw.SpatialJoinQueryFlat() to join polygons and
linestrings but the result is empty despite overlap in the polygons and
linestrings.

I am wondering if JoinQueryRaw.SpatialJoinQueryFlat can do the join I am
after or if I need to do a RangeQuery.SpatialRangeQuery().

Also, how do I get posting rights on the Apache Sedona community server
?

Tnx for any pointers. Regards, Mark
