GPS / GNSS Capture
Integrate external RTK receivers (Trimble, Leica, u-blox) for sub-centimetre field positions. Supports NMEA 0183 over Bluetooth, USB, and Wi-Fi, with automatic datum transformation to any EPSG on capture.
Real-time Field Sync
Field edits on the map
in under 100ms.
WebSocket-powered GPS data capture with sub-100ms server push, offline-first conflict resolution, and instant map refresh. Built for survey teams who cannot afford to lose a single point — whether they have signal or not.
- End-to-end sync latency
- < 100ms
- Full functionality without connectivity
- Offline-first
- Sub-centimetre GPS integration
- GNSS RTK
- Native and PWA support

Capabilities
Everything a field survey team needs
From sub-centimetre GNSS capture to instant office map refresh — Field Sync covers the complete data collection lifecycle.
Offline-first Architecture
Full create, edit, and delete capability with no connectivity whatsoever. The local SQLite store mirrors the server schema; automatic sync triggers on reconnect with zero data loss.
Conflict Resolution
3-way merge with visual diff when two field workers edit the same feature simultaneously. Accept theirs, keep yours, or merge attribute-by-attribute — all decisions are audit-logged.
Real-time Map Push
WebSocket broadcasting pushes field edits to the office map in under 100ms. Office teams see geometry and attribute changes appear live on the map without refreshing.
Photo & Document Capture
Attach geotagged photos, voice notes, and freehand sketches to any spatial feature. Files are compressed and queued for upload; full-resolution originals sync when bandwidth allows.
Automated QA Checks
On-device validation of coordinate precision, attribute completeness, and boundary rules before transmission. Invalid features are flagged with plain-English error messages — not raw schema errors.
Integrations
Works with your existing GIS stack
Field Sync connects to the tools your teams already use — no rip-and-replace required.
QGIS Plugin
Native QGIS plugin exposes Field Sync layers as editable vector layers. Edit in the office, push to the field — or pull field edits directly into a QGIS project.
ArcGIS Field Maps Migration
Import existing ArcGIS Field Maps projects, geodatabase schemas, and feature templates with a single upload. No schema rebuild required.
Collector for ArcGIS Data Import
Batch import historical Collector for ArcGIS datasets (File Geodatabase or GeoJSON) to preserve legacy field data in the Field Sync audit trail.
OGC WFS Transactional Write-back
All field edits are written back to the platform WFS-T endpoint, making changes immediately available to any OGC-compliant GIS client — QGIS, MapInfo, FME, and beyond.
Device support
Native on every platform your team uses
Full feature parity across iOS, Android, browser, and Garmin handhelds — one backend, one data model.
| Platform | Details |
|---|---|
| iOS 16+ | Native SwiftUI app — offline maps, RTK Bluetooth, background sync |
| Android 12+ | Native Jetpack Compose app — same feature parity as iOS |
| Progressive Web App | Any modern browser; Service Worker caches map tiles and schema offline |
| Garmin Handhelds | Bluetooth NMEA stream from Garmin Montana, eTrex, and GPSMAP series |
