Convert GDB to E00 Online - Free & Fast

What is GDB?

ESRI File Geodatabase (GDB) is a collection of files in a folder structure that stores vector feature classes, raster datasets, topology rules, and network datasets, serving as the primary geospatial data storage format in ArcGIS.

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 GDB vs E00?

GDB vs E00: Key Differences

• •GDB uses lossless compression while E00 uses lossy compression — this is the fundamental technical difference between the two formats.
• •Moving from GDB (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.
• •GDB files are typically 1MB to 1TB+ depending on data volume while E00 files range 100KB to several GB depending on coverage complexity
• •GDB is optimized for enterprise gis data management, esri ecosystem spatial storage while E00 is designed for legacy arcinfo data migration, gis archival data recovery — choose based on your specific workflow needs

Advantages of GDB

• ✓GDB compresses data using lossless methods, keeping file sizes manageable for Enterprise GIS data management, ESRI ecosystem spatial storage.
• ✓Industry-wide support means GDB files open anywhere — from legacy systems to the latest devices.
• ✓Lossless quality makes GDB the gold standard for archival and master copies.
• ✓From professional software to open-source alternatives, GDB works out of the box.

Advantages of E00

• ✓E00 compresses data using lossy methods, keeping file sizes manageable for Legacy ArcInfo data migration, GIS archival data recovery.
• ✓Industry-wide support means E00 files open anywhere — from legacy systems to the latest devices.
• ✓Small file sizes make E00 ideal for email, web uploads, and cloud storage.
• ✓From professional software to open-source alternatives, E00 works out of the box.

Common Use Cases for GDB to E00 Conversion

Industry Applications

Best Practices for GDB to E00 Conversion

• →When converting GDB 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 GDB
• →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 GDB to E00 Conversion

• !Topology errors in the converted E00 → self-intersecting polygons or duplicate vertices may not transfer cleanly between formats
• !The E00 file coordinate values shifted slightly → datums (WGS84 vs NAD83) differ even when the projection looks similar
• !Time field values were corrupted after converting GDB to E00 → date and time field formatting varies across GIS formats
• !Null geometry features appear in the converted E00 → empty or null-shape records in GDB may cause validation errors in some formats
