Automated Schema Translation
for Complex Geodatabases
Handles Relationship Classes, Domains, and Attachments—No Terminal Required.
Arc2Post is high-fidelity migration software for File Geodatabases (.gdb). If you're on Enterprise SDE, you don't need this tool—but if you're migrating legacy ArcMap data, Arc2Post handles the complexity GDAL skips.
Built for Organizations Migrating Legacy ArcMap Data
Not for developers who enjoy writing GDAL scripts. For GIS Managers with 50+ databases and a Monday deadline.
GIS Managers
Who need to meet migration deadlines
Your team shouldn't spend weeks manually extracting attachments and fixing relationship classes. Arc2Post turns a month-long migration project into a weekend task, producing validated PostgreSQL constraints automatically.
- Meet ArcMap retirement deadlines without hiring consultants
- Export professional migration reports (Markdown/JSON)
- Zero-training required for junior staff
IT & Database Admins
Who need to guarantee data integrity
Hand off geodatabase migrations to staff without teaching them GDAL or Python. Arc2Post ensures every Foreign Key and Domain is mapped correctly to native PostgreSQL types.
- Review schema previews before touching production data
- Maintain referential integrity (Relationship Classes)
- Detailed error logs and ACID-compliant transactions
The Real Cost of Manual Migration
Your time is worth $50-100/hour. Stop wasting it on tedious data exports.
Manual Export/Import
- Export to Shapefiles/GML 8-16 hrs
- Import to PostGIS 8-16 hrs
- Fix relationship & domain loss 12-24 hrs
- Handle attachments manually 8-16 hrs
- Consultant-grade validation 10-20 hrs
Arc2Post Desktop App
- Click "Migrate" in the GUI
- Go do actual work while it runs
- Get fully validated PostgreSQL DB
- Zero data loss guarantee
- Export a professional migration report
Payback: First migration pays for itself 20x over
Why Not Just Use OGR2OGR?
If your geodatabase contains simple feature classes with no relationships, use ogr2ogr—it's free and works perfectly. But for enterprise data, free tools break referential integrity.
Free Scripting
GDAL / ogr2ogr-
Loses Relationship Classes Flattens connections to plain tables, destroying referential integrity.
-
Drops Coded Value Domains Converts validation rules to plain text, losing business logic.
-
Simplifies Geometries Often breaks or simplifies curved segments and annotation layers.
-
Manual Attachments Requires custom Python scripts to extract and link BLOB attachments.
Arc2Post Engine
Automated Migration-
Preserves Relationships Converts ArcMap Relationship Classes to native PostgreSQL Foreign Keys.
-
Native Domain Mapping Maps Coded Value Domains to native ENUM or CHECK constraints.
-
High-Fidelity Geometry Full support for multi-part, Z/M values, and curved segments.
-
Auto-Extracted Attachments Folders organized by feature name, linked automatically in PostgreSQL.
Automated workflow—no scripting required.
A modern GUI designed for professionals, not a clunky Python script.
Browse
Select your .gdb folder — or let it auto-detect from a directory.
Connect
Enter PostgreSQL credentials and test connection — built right in.
Review
Preview tables, row counts, and attachment sizes before migration starts.
Execute
Watch progress bars with real-time ETA while it streams data to PostgreSQL.

What Happens After Migration?
Your data lives natively in PostgreSQL/PostGIS. Now you can:
Desktop GIS
Connect QGIS (free) directly for desktop editing, spatial analysis, and high-quality map production.
Web Mapping
Publish web services instantly via industry-standard open source servers like GeoServer or MapServer.
Custom Applications
Build custom apps and dashboards using standard PostgreSQL drivers (Python, Node.js, Go, etc).
Arc2Post preserves your domains and relationships so QGIS handles your data exactly like ArcMap did—dropdowns work, related tables stay linked.
Built for Production Migrations, Not One-Off Scripts
Arc2Post handles the schema complexity that breaks standard open-source tools.
Complete Schema Translation
Relationship Classes become Foreign Keys. Coded Value Domains become PostgreSQL ENUMs. Maintains data integrity that took years to build.
Zero Data Loss
Binary GUIDs to UUIDs. Microsecond precision preserved. Empty vs NULL logic maintained. Binary attachments auto-extracted.
Complex Geometries
Full support for multi-part geometries, curved segments, and 3D (Z) / Measure (M) coordinates that ogr2ogr often simplifies.
Performance & Scalability
Memory-efficient row streaming. Tune batch sizes from 1K to 50K. Multi-threaded processing uses all CPU cores. Tested with millions of rows.
Migration Reliability
Pre-migration connection checks. Post-migration ST_IsValid geometry checks. Resume capability for failed migrations. ACID compliant.
Delegate Without Training
Your senior dev shouldn't spend 3 days writing GDAL scripts. Arc2Post turns complex geodatabase logic into validated PostgreSQL constraints automatically.
Production-Grade Migration Tooling
At $179, you're not paying for a fancy wrapper around ogr2ogr. You're paying for a engine that handles the advanced geodatabase features scripts ignore.
Visual Progress + ETA
Real-time progress bars for every table with time-remaining estimates. Know exactly when a 10GB migration will finish.
Attachment Browser
Browse extracted images and PDFs in organized, named folders right from the app—no digging through blob dumps.
Batch Size Slider
Tune performance from 1K to 50K rows per batch with a simple slider to match your server's hardware perfectly.
Curve & Multi-part Support
Preserves complex geometries like curved segments and multi-part features that standard tools often simplify or break.
Migration Reports
Export professional Markdown or JSON migration reports for audit trails and project documentation.
Cancel & Resume
Safe pause and resume if your connection drops mid-migration. Pick up exactly where you left off.
"Will this break my data?"
Arc2Post never touches your source GDB. The destination PostgreSQL database is created fresh. Your original data is read-only throughout the entire process.
During migration, a live validation screen turns green row-by-row as each table is confirmed. If anything fails, you get a detailed error log — not a cryptic Python traceback — so you know exactly what happened and why.
Source GDB untouched
Read-only access throughout
Row-by-row validation
Watch it turn green live
Plain-English error logs
Not a cryptic traceback
