GeoSpark is a cluster computing system for processing large-scale spatial data. GeoSpark extends Apache Spark with a set of out-of-the-box Spatial Resilient Distributed Datasets (SRDDs) that efficiently load, process, and analyze large-scale spatial data across machines. GeoSpark provides APIs for Apache Spark programmer to easily develop their spatial analysis programs with Spatial Resilient Distributed Datasets (SRDDs) which have in house support for geometrical and Spatial Queries (Range, K Nearest Neighbors, Join).
GeoSpark artifacts are hosted in Maven Central: Maven Central Coordinates
Supported Spatial RDDs: PointRDD, RectangleRDD, PolygonRDD, LineStringRDD
Native input format support: CSV, TSV, WKT, GeoJSON
User-supplied input format mapper: Any input formats
Supported Spatial Partitioning techniques: R-Tree, Voronoi diagram, Uniform grids (Experimental), Hilbert Curve (Experimental)
Supported Spatial Indexes: Quad-Tree and R-Tree. R-Tree supports Spatial K Nearest Neighbors query.
Inside, Overlap, DatasetBoundary, Minimum Bounding Rectangl, Polygon Union
Spatial Range Query, Spatial Join Query, and Spatial K Nearest Neighbors Query.

Babylon is a large-scale in-memory geospatial visualization system.
Babylon provides native support for general cartographic design by extending GeoSpark to process large-scale spatial data. It can visulize Spatial RDD and Spatial Queries and render super high resolution image in parallel.
Babylon and GeoSpark are integrated together. You just need to import GeoSpark and enjoy them! More details are available here: Babylon GeoSpatial Visualization
