Apache Sedona is an open-source cluster computing system built for processing large-scale spatial data across distributed environments. Originally developed at Arizona State University under the name GeoSpark, in the paper “Spatial Data Management in Apache Spark: The GeoSpark Perspective and Beyond” by Jia Yu and Mohamed Sarwat, it is now a top-level Apache Software Foundation project used by organizations across transportation, logistics, environmental monitoring, insurance, and urban planning. This page covers what Apache Sedona is, how it processes spatial queries, common use cases, and how to get started.
Apache Sedona treats spatial data as a first-class citizen by extending distributed compute frameworks including Apache Spark, Apache Flink, and Snowflake with specialized data types, spatial operations, and indexing techniques optimized for spatial workloads. Unlike general-purpose compute frameworks, Sedona is purpose-built for the unique challenges of spatial data, including complex geometries, coordinate systems, and spatial relationships that standard data types cannot handle efficiently. The following section outlines how Apache Sedona processes spatial queries from data ingestion through to distributed execution.
Apache Sedona supports multiple programming languages, including Python, Scala, Java, R, and SQL, making it accessible to a wide range of data engineering and analytics workflows. Developers can interact with Apache Sedona through whichever language fits their existing stack.
On the integrations side, Apache Sedona runs on Apache Spark, Apache Flink, and Snowflake. Each runtime serves a different need: Apache Spark for large-scale distributed batch processing, Apache Flink for real-time streaming spatial analytics, and Snowflake for teams running spatial workloads inside a cloud data warehouse environment.
The first step in spatial query processing is to ingest geospatial data into Apache Sedona. Data can be loaded from various sources such as files (Shapefiles, GeoJSON, Parquet, GeoTiff, CSV, etc) or databases into Apache Sedona’s in-memory distributed spatial data structures (typically the Spatial DataFrame).
Next, Sedona makes use of spatial indexing techniques to accelerate query processing, such as R-trees or Quad trees. The spatial index is used to partition the data into smaller, manageable units, enabling efficient data retrieval during query processing.
Once the data is loaded and indexed spatial queries can be executed using Sedona’s query execution engine. Sedona supports a wide range of spatial operations, such as spatial joins, distance calculations, and spatial aggregations.
Sedona optimizes spatial queries to improve performance. The query optimizer determines an efficient query plan by considering the spatial predicates, available indexes, and the distribution of data across the cluster.
Spatial queries are executed in a distributed manner using Sedona’s computational capabilities. The query execution engine distributes the query workload across the cluster, with each node processing a portion of the data. Intermediate results are combined to produce the final result set. Since spatial objects can be very complex with many coordinates and topology, Sedona implements a custom serializer for efficiently moving spatial data throughout the cluster.
Organizations use Apache Sedona for a range of large-scale geospatial data processing tasks, including
Many of these use cases can be described as geospatial ETL operations. ETL (extract, transform, load) is a data integration process that involves retrieving data from various sources, transforming and combining these datasets, then loading the transformed data into a target system or format for reporting or further analysis. Geospatial ETL shares many of the same challenges and requirements of traditional ETL processes with the additional complexities of managing the geospatial component of the data, working with geospatial data sources and formats, spatial data types and transformations, as well as the scalability and performance considerations required for spatial operations such as joins based on spatial relationships.

Apache Sedona is one of the most widely adopted geospatial analytics libraries in the distributed computing ecosystem, with over 68 million downloads and active use across industries including transportation, logistics, environmental monitoring, and insurance. As a top-level Apache Software Foundation (ASF) project since February 2023, Sedona’s governance, licensing, and community participation align with ASF principles. The project has an active and growing developer community, with contributors from many types of organizations and more than 100 individuals advancing geospatial analytics and distributed computing.
Organizations in industries including transportation, urban planning, environmental monitoring, logistics, insurance and risk analysis and more have adopted Apache Sedona. These organizations leverage Sedona’s capabilities to perform large-scale geospatial analysis, extract insights from geospatial data and build geospatial analytical applications at scale.
Apache Sedona has been featured in conferences, workshops, and research publications related to geospatial analytics, distributed computing, and big data processing. For a deeper look at Apache Sedona’s adoption and real-world impact, watch Iceberg Geo Type: Transforming Geospatial Data Management at Scale presented by Jia Yu and Szehon Ho at at Data + AI Summit.

Apache Sedona is an open-source cluster computing system for processing large-scale spatial data. It extends distributed compute frameworks including Apache Spark, Apache Flink, and Snowflake with spatial data types, spatial indexing, and 300+ spatial SQL functions for vector and raster data, and also runs on a single node through SedonaDB.
Apache Sedona is used for large-scale geospatial ETL and spatial analysis. Common uses include combining vector parcel data with raster layers for environmental reports, generating planetary-scale GeoParquet datasets, converting billions of GPS points into vehicle routes, and enriching parcel data with demographic and environmental layers for real estate analysis.
Apache Sedona was created by Jia Yu and Mohamed (Mo) Sarwat. It originated as GeoSpark, introduced in their 2018 research paper “Spatial Data Management in Apache Spark: The GeoSpark Perspective and Beyond.” The project later joined the Apache Software Foundation and became a top-level Apache project in February 2023. The two researchers went on to found Wherobots.
Apache Sedona supports Python, Scala, Java, R, and SQL.
Yes. Apache Sedona is free and open source. It is a top-level Apache Software Foundation project, released under the Apache License 2.0, which permits free use, modification, and distribution.
Apache Sedona ingests spatial data from formats like Shapefiles, GeoJSON, GeoTIFF, Parquet, and CSV into distributed spatial DataFrames. It applies spatial indexing such as R-trees and quad-trees to partition the data, then runs spatial operations like joins, distance calculations, and aggregations across the cluster, combining the partial results into a final output.
How Bad Telemetry Data Sabotages Modern Fleets
By the Teams at Action Engine & Wherobots Fleet monitoring is undergoing a generational shift. Fleet monitoring, the systems that ingest and analyze vehicle telemetry to track fleet health, performance, and safety, has become the foundation of how operators run vehicles, not just track them. Modern vehicles generate orders of magnitude more telemetry than even […]

Spatial Data in Apache Iceberg: Optimizations and Management That Matter
Spatial data in Apache Iceberg needs different optimization than tabular data. A geometry column has no natural sort order, so unsorted files carry wide, overlapping bounding boxes and query planners cannot prune them… At all… This behaviour turns a selective spatial filter into a full table scan. A second problem compounds it: one oversized geometry […]
