No, converting BNA to GEOJSON does not cause additional quality loss — GEOJSON uses lossless compression. However, any artifacts already present in the original BNA file will persist in the GEOJSON output.
GEOJSON files are typically 2-5x larger than equivalent BNA files because GEOJSON preserves all pixel data. This is expected and necessary for lossless quality.
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.
GeoJSON is the standard format for web-based geographic data, encoding points, lines, polygons, and feature collections in JavaScript Object Notation.
Reach for BNA when your priority is atlas gis boundary exchange, regional mapping, legacy spatial data conversion — its efficient compression makes sharing fast and storage minimal.
Reach for GEOJSON when your priority is web mapping, geospatial apis, data interchange — its uncompromising quality ensures every detail is preserved.
