Scala Library with H3 Spatial Index and Apache Sedona

Overview

This Scala library provides a set of utilities for working with spatial data using the H3 spatial index and Apache Sedona (formerly known as GeoSpark). H3 is a versatile hexagon-based spatial indexing system, and Apache Sedona is a distributed computing library for processing large-scale spatial data.

Features

• H3 Spatial Indexing: Leverage the power of H3 to efficiently index and query spatial data using hexagons.
• Integration with Apache Sedona: Seamlessly integrate with Apache Sedona for distributed spatial data processing.
• Spatial Operations: Perform various spatial operations such as point-in-polygon, distance calculations, and more.
• Scala API: Utilize a user-friendly Scala API to easily incorporate spatial functionalities into your Scala applications.

Predicate functions

• pointInPolygonJoin: Joining datasets based on the point belonging to one set to the polygon in another set.
• geometryInsidePolygonJoin: Joining datasets based on the polygon belonging to one set to the polygon in another set.
• geometriesIntersectJoin: Joining datasets based on the intersection of a polygon from one set with a polygon from another set.
• getPointsInRangeFromPoints: Joining datasets based on the distance between points occurring in the datasets.
• getPointsInRangeFromPolygon: Joining datasets based on the distance between a point in one dataset and a polygon in another.
• getPolygonsInRangeFromPolygons: Joining datasets based on the distance between a polygon in one dataset and a polygon in another.
