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.

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 E00 vs GPKG?

E00 vs GPKG: Key Differences

• •E00 uses lossy compression while GPKG uses lossless compression — this is the fundamental technical difference between the two formats.
• •Moving from E00 (lossless) to GPKG (lossless) means the output file will be larger — but every bit of the original is preserved.
• •How transparency is handled: GPKG supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: 100KB to several GB depending on coverage complexity for E00 vs 10KB to several GB depending on feature density for GPKG.
• •E00 is optimized for legacy arcinfo data migration, gis archival data recovery while GPKG is designed for mobile gis, offline mapping, portable geospatial data exchange — choose based on your specific workflow needs

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.

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.

Common Use Cases for E00 to GPKG Conversion

Industry Applications

Best Practices for E00 to GPKG Conversion

• →When converting E00 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 E00
• →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 E00 to GPKG Conversion

• !GPKG features land in the wrong place after E00 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
• !E00 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
