Tileverse Range Reader¶

A high-performance Java library for reading byte ranges from various data sources including local files, HTTP servers, and cloud storage services.

The Cloud-Native Geospatial Challenge¶

The geospatial data landscape has fundamentally shifted from traditional "download-and-process" workflows to cloud-native patterns. Modern formats like Cloud Optimized GeoTIFF (COG), PMTiles, GeoParquet, Zarr, and FlatGeobuf are explicitly designed to leverage HTTP range requests, allowing applications to fetch only the specific byte ranges needed for a query rather than downloading entire multi-gigabyte files.

However, the Java ecosystem has suffered from significant fragmentation in this space. Tileverse Range Reader provides the missing architectural layer that the Java geospatial ecosystem needs—a lightweight, extensible, and cloud-agnostic abstraction for range-based I/O operations.

Key Features¶

• Multiple Data Sources: Local files, HTTP/HTTPS, Amazon S3, Azure Blob Storage, and Google Cloud Storage.
• High Performance: Multi-level caching, block alignment, and concurrent access.
• Flexible Architecture: Composable functionality through decorators and builder APIs.
• Comprehensive Authentication: Support for a wide range of authentication mechanisms.

Getting Started¶
