Convert WKT to BNA Online - Free & Fast

What is WKT?

WKT (Well-Known Text) is a simple text markup language for representing geographic geometry objects like points, lines, polygons, and coordinate reference systems.

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 WKT vs BNA?

WKT vs BNA: Key Differences

• •WKT and BNA diverge on compression: lossless compression for the source, lossy compression for the target.
• •Moving from WKT (lossy) to BNA (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: BNA does not support alpha channels — transparent areas in the source will become opaque.
• •WKT files are typically Very compact text representation while BNA files range 1KB to 50MB depending on boundary complexity
• •Primary audience: WKT is built for database spatial queries, geographic geometry exchange, cad scenarios, while BNA focuses on atlas gis boundary exchange, regional mapping, legacy spatial data conversion — pick the format that matches your output requirement.

Advantages of WKT

• ✓The lossless nature of WKT means file sizes stay reasonable while handling Database spatial queries, geographic geometry exchange, CAD efficiently.
• ✓From mobile devices to enterprise servers, WKT is recognized and supported everywhere.
• ✓The trade-off for WKT's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓WKT is a first-class citizen in all major software ecosystems, from creative suites to development environments.

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 WKT to BNA Conversion

Industry Applications

Best Practices for WKT to BNA Conversion

• →For WKT to BNA: verify that field name length limits in BNA do not truncate attribute column names
• →Test a subset of features first — especially if the dataset contains mixed geometry types
• →Confirm that multi-part geometries (multi-polygons, multi-lines) remain intact after conversion
• →Check for any required sidecar files (.prj, .shx, .qpj) that the target format needs
• →Validate the converted file using a GIS validation tool before relying on it in production

Troubleshooting WKT to BNA Conversion

• !BNA features land in the wrong place after WKT 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
• !WKT 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
