Convert BNA to GPKG Online - Free & Fast

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.

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.

When Should You Use BNA vs GPKG?

BNA vs GPKG: Key Differences

• •BNA and GPKG diverge on compression: lossy compression for the source, lossless compression for the target.
• •Converting from BNA to GPKG changes compression type: lossless source becomes larger but with full quality preservation.
• •Transparency: N/A - SQLite binary format
• •Storage footprint: 1KB to 50MB depending on boundary complexity for BNA vs 10KB to several GB depending on feature density for GPKG.
• •BNA is optimized for atlas gis boundary exchange, regional mapping, legacy spatial data conversion while GPKG is designed for mobile gis, offline mapping, portable geospatial data exchange — choose based on your specific workflow needs

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.

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.

Common Use Cases for BNA to GPKG Conversion

Industry Applications

Best Practices for BNA to GPKG Conversion

• →When converting BNA to GPKG: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — GPKG should retain all fields from BNA
• →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 BNA to GPKG Conversion

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