ADR-0003: I/O format choices

• Status: Accepted
• Date: 2025-08-16

Context

pyramids processes raster and vector geospatial data and must interoperate with common GIS tools and libraries.

Decision

• Raster: prioritize GeoTIFF for read/write; support ASCII Grid for simple interchange; support NetCDF for multi-dimensional datasets when appropriate.
• Vector: prioritize GeoJSON for web interoperability; support Shapefile and GeoPackage for desktop GIS.

Consequences

• Users can rely on standard formats across workflows.
• Additional drivers may be enabled via GDAL installation; docs should clarify environment requirements.
