Survey Management System
Digital archiving system for Nigerian cadastral survey records with DWG/DXF import, AI data extraction, coordinate/traverse calculations, document management, a built-in survey database file (nothing to install) or a shared PostgreSQL/PostGIS database, and PlotAccess — a road-aware, exact-area cadastral subdivision engine.
Comprehensive digital archiving system for Nigerian survey records, now with PlotAccess: an automated, road-aware cadastral subdivision engine.
FEATURES:
- PlotAccess — road-aware, exact-area cadastral subdivision, with
automatic road layout and hard road-access enforcement
- AutoCAD DWG and DXF import with AI-powered metadata extraction (no
extra software to install)
- Bearing and distance traverse calculator (WCB and quadrant, DMS input)
- 1:5000 Nigerian Survey Regulations precision ratio check
- Coordinate input with PostGIS spatial storage
- Document upload with MD5 checksum integrity verification
- Three-tier access control (superuser, surveyor, viewer)
- Full audit trail of all actions
- Global search across all database tables
- Adjoining survey boundary detection
- Works on QGIS 3.22+ and QGIS 4
- First-run setup wizard asks one question: just me, or a shared office?
- Just me: all records in one survey database file (GeoPackage) on this
computer -- nothing else to install; one-click backup
- Shared office: PostgreSQL + PostGIS server (existing server, or an
advanced one-click server on this computer via Docker)
REQUIREMENTS: nothing beyond QGIS for the survey database file, DWG
import and DXF import/export (the plugin reads DWG and DXF itself). Optional
parts install themselves with one click when first used: Shapely
(PlotAccess, about 2 MB) and psycopg2 (shared office database: a
PostgreSQL 12+ server with PostGIS, or Docker Desktop).
