Surveyza
Geospatial survey intelligence for land professionals
Surveyza unifies field capture, parcel geometry, control points and deliverable review inside a single spatial workspace. Crews work offline in the field, sync when connectivity returns, and office reviewers approve geometry against an auditable chain of evidence.

Business problems solved
What was broken
Fragmented field capture
Survey crews juggle paper notes, handheld exports and desktop CAD, losing traceability between observation and deliverable.
No spatial source of truth
Parcel geometry lives across shapefiles, email attachments and county portals with no reconciliation layer.
Slow QA turnaround
Manual review cycles delay deliverables by days and make defect attribution nearly impossible.
Primary features
What we built
Spatial workspace
PostGIS-backed parcel, boundary and control-point layers with topology validation.
Offline field mode
Conflict-aware sync queue so crews capture without connectivity and reconcile later.
Deliverable review
Side-by-side geometry diffing with reviewer annotations and approval gates.
Evidence chain
Every vertex traces to an observation, device, crew member and timestamp.

Workflow walkthrough
How work moves through it
- 1
Field capture
Crew records observations offline with device metadata attached.
- 2
Sync & reconcile
Queue replays to the server, flags conflicting geometry for human review.
- 3
Topology validation
Automated checks for gaps, overlaps and closure error tolerance.
- 4
Reviewer approval
Office reviewer diffs geometry versions and signs off.
- 5
Deliverable export
Signed packages generated with a full evidence chain.
