Hi @snowch , JTSplus adds some new functions and code into JTS and so that it uses the same license of JTS (Eclipse license). The license is mentioned here: https://github.com/locationtech/jts...

@geoHeil , STR-Tree KNN search has been merged into JTS official repository 1.15-snapshot. But I don't think the rest of JTSplus (R-Tree/Quad-Tree spatial partitioning, Geometry equality check) will be merged...

If you want to use ./bin/spark-submit, you must change the dependency packaging scope from "compile" to "provided". Otherwise, sbt will package Spark itself into your fat jar and eventually lead...

@YaboSun This is because of Spark's dependency conflict. This is an expected error. 1. To run this project in IDE, do not change anything and DO NOT PACKAGE. 2. To...

Hi, In each geometry of the rawSpatialRDD of SpatialRDD, there is an attribute called UserData. You can concatenate all other attributes to a string and store it there. This is...

@ps-spark Each object in any rawSpatialRDD or pairRDD is a Geometry. Its other attributes are stored in its UserData attributes. You also can concatenate any strings by "tab" and store...

@kaiwinter @dr-jts Thanks for the great work. Is there a reason why this PR hasn't been merged after a year? Is there anything others could help? WKB format is often...

@jwass Is there a reason why you want to use the Sedona rdd-based spatial partitioning? This is considered as low-level API and only used for spatial join. Most importantly, given...

## R-Tree for clustering If we just talk about how to cluster / reorg data based on the spatial proximity, any space filling curve or H3/S2/GeoHash will do the same...

We also conducted a similar benchmark to study the pruning power of S2/GeoHash (e..g, overlapping area around partitions), You can see it here: https://wherobots.com/spatial-data-geoparquet-and-apache-sedona/
