Convert GML to E00 Online - Free & Fast

What is GML?

GML (Geography Markup Language) is the OGC standard XML grammar for encoding geographic features with full coordinate reference system support.

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 GML vs E00?

GML vs E00: Key Differences

• •GML and E00 diverge on compression: lossless compression for the source, lossy compression for the target.
• •Converting from GML to E00 changes compression type: lossy source becomes smaller but with some quality tradeoff.
• •Transparency: Yes - E00 is an ASCII text format — converting from GML will merge transparency into a solid background
• •Storage footprint: Larger than Shapefile due to verbose XML structure for GML vs 100KB to several GB depending on coverage complexity for E00.
• •Use case fit: GML targets ogc-compliant geospatial data exchange, enterprise gis and E00 targets legacy arcinfo data migration, gis archival data recovery — your choice depends on which workflow stage you are serving.

Advantages of GML

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

Advantages of E00

• ✓At its core, E00 relies on lossy encoding — a design choice that makes it perfect for Legacy ArcInfo data migration, GIS archival data recovery.
• ✓You won't run into compatibility issues with E00 — it's a universal standard across platforms.
• ✓File size management with E00: aggressive compression with minimal visible quality loss.
• ✓Every major application in the Legacy ArcInfo data migration, GIS archival data recovery space supports E00 natively.

Common Use Cases for GML to E00 Conversion

Industry Applications

Best Practices for GML to E00 Conversion

• →For GML to E00: verify that field name length limits in E00 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 GML to E00 Conversion

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