GeoSpark v0.5.2-Spark-1.x

GeoSpark 0.5.2 is a maintenance release on GeoSpark 0.5.X. This release is compatible with Apache Spark 1.X line.

Bug fix: Fix Issue #58 and Issue #60; Performance enhancement: (1) Deprecate all old Spatial RDD constructors. See the JavaDoc here. (2) Recommend the new SRDD constructors which take an additional RDD storage level and automatically cache rawSpatialRDD to accelerate internal SRDD analyze step

GeoSpark v0.5.0

GeoSpark 0.5.0 is the fifth release on GeoSpark 0.X line. It contains Major updates: We are pleased to announce the initial version of Babylon a large-scale in-memory geospatial visualization system extending GeoSpark. Babylon and GeoSpark are integrated together. You can just import GeoSpark and enjoy! More detials are available here: Babylon GeoSpatial Visualization

GeoSpark v0.4.0

GeoSpark 0.4.0 is the fourth release on GeoSpark 0.X line. It contains Major updates: (Example) 1. Refactor constructor API usage. 2. Simplify Spatial Join Query API. 3. Add native support for LineStringRDD; Functionality enhancement: 1. Release the persist function back to users. 2. Add more exception explanations.

GeoSpark v0.3.2

GeoSpark 0.3.2 is a maintenance release containing functionality enhancement: 1. JTSplus Spatial Objects now carry the original input data. Each object stores "UserData" and provides getter and setter. 2. Add a new SpatialRDD constructor to transform a regular data RDD to a spatial partitioned SpatialRDD.

The precompiled GeoSpark jar uses Apache Spark 2.0.1 as a dependency but it should work for other Apache Spark 2.X versions.

GeoSpark v0.3.1

GeoSpark 0.3.1 is a maintenance release containing bug fixes: support Apache Spark 2.X version, fix a bug which results in inaccurate results when doing join queries, add more unit test cases

The precompiled GeoSpark jars use Apache Spark 2.0.1 or Apache Spark 1.6.2 as a dependency. Please change it in "Pom.xml" if you are using different Spark.

GeoSpark v0.3

This version contains load balanced spatial partitioning techniques (R-Tree and Voronoi); global and local index; optimized range, join and KNN for iterative spatial data mining.

The precompiled GeoSpark jar uses Spark 1.6.1 as a dependency. Please change it in "Pom.xml" if you are using different Spark.

GeoSpark_SourceCode_v0.2

This release includes PointRDD, RectangleRDD, PolygonRDD, CircleRDD as well as corresponding IndexRDD. Regarding SpatialRDD API usage, please refer GeoSpark Java API Doc.
