O3NEX
Professional surveying & geospatial drafting software — from coordinates and control to a finished, signed survey plan.
Charting and control plans composed automatically: bearings, distances, beacons, coordinate ties and title blocks, ready for signature.
Control networks, traverse generation clockwise from true north, observation arcs and a vector editor for NL pegs and annotation.
The official Lagos State control dataset installed offline, in Minna / UTM zone 31N, read-only.
PDF, PNG, DXF in metres and AutoCAD script — every export is the same drawing you see on screen.
Sheet templates with a layout editor: the built-in Nigerian survey sheet, your firm's title block, any paper size.
Activate once; GEO3NEX keeps working in the field without a connection and verifies when you are back online.
