Convert GPKG to BNA Online - Free & Fast

What is GPKG?

GeoPackage (GPKG) is an open, standards-based, portable SQLite format for storing vector features, tiled map overlays, and attribute data in a single file, designed as a modern replacement for the Shapefile by the Open Geospatial Consortium.

What is BNA?

Atlas Boundaries (BNA) is a simple ASCII coordinate format for storing polygon boundary data, originally developed by Atlas GIS for representing area features like postal codes, sales territories, and administrative regions as coordinate lists.

When Should You Use GPKG vs BNA?

GPKG vs BNA: Key Differences

• •GPKG uses lossless compression while BNA uses lossy compression — this is the fundamental technical difference between the two formats.
• •Converting from GPKG to BNA changes compression type: lossy source becomes smaller but with some quality tradeoff.
• •Transparency: Yes - BNA is a plain text format — converting from GPKG will merge transparency into a solid background
• •Storage footprint: 10KB to several GB depending on feature density for GPKG vs 1KB to 50MB depending on boundary complexity for BNA.
• •GPKG is optimized for mobile gis, offline mapping, portable geospatial data exchange while BNA is designed for atlas gis boundary exchange, regional mapping, legacy spatial data conversion — choose based on your specific workflow needs

Advantages of GPKG

• ✓GPKG uses lossless compression tailored for Mobile GIS, offline mapping, portable geospatial data exchange.
• ✓GPKG is supported natively on virtually every device, browser, and operating system.
• ✓GPKG files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓GPKG integrates seamlessly with all major creative tools and workflows.

Advantages of BNA

• ✓At its core, BNA relies on lossy encoding — a design choice that makes it perfect for Atlas GIS boundary exchange, regional mapping, legacy spatial data conversion.
• ✓You won't run into compatibility issues with BNA — it's a universal standard across platforms.
• ✓File size management with BNA: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Atlas GIS boundary exchange, regional mapping, legacy spatial data conversion space supports BNA natively.

Common Use Cases for GPKG to BNA Conversion

Industry Applications

Best Practices for GPKG to BNA Conversion

• →When converting GPKG to BNA: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — BNA should retain all fields from GPKG
• →Check geometry types (point, line, polygon) map cleanly between the two formats
• →Verify that z/elevation values and topology survive the conversion when working with terrain data
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting GPKG to BNA Conversion

• !BNA features land in the wrong place after GPKG to BNA → verify the CRS/projection; mismatched coordinate systems shift geometry
• !Attribute columns missing in BNA → some GIS formats have field name length or type limits; rename or cast columns first
• !GPKG to BNA drops the z/elevation dimension → pick a target format that supports 3D geometry
• !BNA file won't open in your GIS app → confirm the format version and any required sidecar files (e.g. .prj, .shx) are present
