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 E00?

ArcInfo Exchange (E00) is a proprietary interchange format developed by ESRI for exporting and importing Arc/Info coverages, encoding vector topology, attributes, and raster data in an ASCII text file for data migration between GIS systems.

When Should You Use GPKG vs E00?

GPKG vs E00: Key Differences

• •GPKG uses lossless compression while E00 uses lossy compression — this is the fundamental technical difference between the two formats.
• •Moving from GPKG (lossy) to E00 (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: E00 does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: 10KB to several GB depending on feature density for GPKG vs 100KB to several GB depending on coverage complexity for E00.
• •GPKG is optimized for mobile gis, offline mapping, portable geospatial data exchange while E00 is designed for legacy arcinfo data migration, gis archival data recovery — choose based on your specific workflow needs

Advantages of GPKG

• ✓At its core, GPKG relies on lossless encoding — a design choice that makes it perfect for Mobile GIS, offline mapping, portable geospatial data exchange.
• ✓You won't run into compatibility issues with GPKG — it's a universal standard across platforms.
• ✓File size management with GPKG: larger files guaranteed to match the original exactly.
• ✓Every major application in the Mobile GIS, offline mapping, portable geospatial data exchange space supports GPKG natively.

Advantages of E00

• ✓E00 applies lossy compression specifically calibrated for Legacy ArcInfo data migration, GIS archival data recovery.
• ✓E00 enjoys broad native support across operating systems, browsers, and creative tools alike.
• ✓E00 delivers impressive compression ratios, shrinking files dramatically while keeping visual quality high.
• ✓You will find E00 support built into virtually every tool that handles Legacy ArcInfo data migration, GIS archival data recovery — no plugins or converters needed.

Common Use Cases for GPKG to E00 Conversion

Industry Applications

Best Practices for GPKG to E00 Conversion

• →When converting GPKG to E00: confirm the coordinate reference system (CRS / projection) is preserved or explicitly reprojected
• →Keep attribute tables and feature metadata intact — E00 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 E00 Conversion

• !E00 features land in the wrong place after GPKG to E00 → verify the CRS/projection; mismatched coordinate systems shift geometry
• !Attribute columns missing in E00 → some GIS formats have field name length or type limits; rename or cast columns first
• !GPKG to E00 drops the z/elevation dimension → pick a target format that supports 3D geometry
• !E00 file won't open in your GIS app → confirm the format version and any required sidecar files (e.g. .prj, .shx) are present
