Opens your scan projects directly
Import a Trimble .tdx project or .tzf folder, a Trimble RealWorks .rwp project with its station color and photospheres, or multi-scan E57, and add more scans to the same workspace later.
Surveyor
Register, extract, check and deliver point clouds with billions of points.
Surveyor is a Windows workstation for laser-scan production. Bring in your scan projects, register them station by station, trace curbs and linework, set survey points with your feature codes, check the result, and deliver LAS, E57, LandXML and DXF from one project.

Standouts
Why Surveyor.
Station by station
Registration that refuses rather than guesses
Every station comes back placed, not placed or unchanged, with the reason. A disconnected part of the network moves only when two independent sets of reference stations agree, and a station the run refuses keeps the position it had.
One stroke
Brush a curb, get top of curb and flowline
One brush stroke along a curb gives a top-of-curb and a flowline 3D polyline, editable before and after you accept them, with checks for crossings and low curb reveal at review, at Accept and after export.
An assistant that works offline
The built-in assistant runs on your machine and answers only from Surveyor's help and bundled federal survey references, including USACE Engineer Manuals, the USFWS Land Survey Handbook and FGDC standards, with a citation for every answer. When it has no record, it says so.
Units and coordinates stay correct
US survey feet are exact and kept separate from international feet, a file's own metadata never overwrites the coordinate system you declared, and a spatial export without a declared coordinate system is blocked.
Your source data is never touched
Projects keep hash-chained restore points, restoring never destroys work, and when a project moves, its files are re-pointed only when their identity is proven.

Real screens, real data.
Overview
The whole job, from raw scans to deliverables.
Surveyor is organized the way a scan job runs: bring the scans in, register them, clean and classify, extract what you will draft, check it, and deliver. Each stage works on the same project, so nothing is exported and re-imported along the way.
Register in the project
Import Trimble and RealWorks projects or E57 scans, place and refine stations with a report for each one, and georeference to your control.
Extract what you draft
Trace curbs and breaklines with the brush, and set survey points with your Trimble FXL or CSV feature codes to drive field-to-finish linework.
Check before you deliver
Measure, compare against a surface or an earlier scan, map coverage gaps, and deliver with a manifest of exactly what was produced.
Features
What Surveyor does.
Every common scan source in one project
Open LAS, LAZ, E57, PLY (including Gaussian splats), PTS and PTX, or Paradigm Geospatial's own PGC2 and PGCV formats. Import Trimble .tdx projects, .tzf folders and RealWorks .rwp projects, and add scans to an existing workspace.
- Trimble .tdx, .tzf and RealWorks .rwp
- LAS, LAZ, E57, PLY, PTS and PTX
- Geotagged photos, including HEIC, shown in the cloud
Registration you can audit
Place stations automatically, by matched picks in split view or photospheres, by targets, or with a drag gizmo; nothing is written until you commit. Register against references, refine the whole network, and level a station to it.
- A placed / not placed / unchanged report for every station
- Nothing written until you commit
- Georeference to PNEZD control with live residuals and check points
One-click classification you can review
Lasso, mark noise and assign classes by hand, or classify in one click into ground, medium and high vegetation, building, wire, pole, sign, retaining wall and noise, then turn classes on and off to check the result.
- Lasso selection and noise marking
- One-click classification
- Per-class visibility for review
Curbs, linework and coded points
Trace a curb to get top of curb and flowline, draw breaklines on a chosen layer or code, and import or export survey points with column mapping, US survey feet and EPSG reprojection. Trimble FXL or CSV feature codes drive field-to-finish linework.
- Top of curb and flowline from one stroke
- Survey points with your feature codes
- Linework QA for crossings and low curb reveal
Computations, surfaces and meshes
Inverse, traverse leg, intersection and offset from picked points; DEM and LandXML surfaces with contours, volumes, sections and surface compare; meshes with GLB export; and fly-through video.
- Inverse, traverse leg, intersection and offset
- Surfaces, contours, volumes and sections
- Meshes, Gaussian splats and fly-throughs
Quality checks before anything leaves
Measure distance (3D, horizontal and vertical), path, angle, perpendicular, radial and area; map deviation from a mesh or TIN surface or from an earlier scan; and find coverage gaps.
- Deviation against a surface or an earlier epoch
- Coverage-gap map
- Airfield obstruction-surface screening (UFC 3-260-01)
Deliveries that document themselves
Profile, preflight, build, validate and publish LAS 1.4, LAZ, E57, PGC2, LandXML 1.2, Shapefile, CSV, DXF linework, a project report and a zipped archive. Each delivery carries a manifest of the profile, lineage, coordinates, software, file sizes and checksums.
- A manifest with checksums for every delivery
- Export the whole cloud, chosen scans or a group
- Pack & Go for hand-off
Help that stays on your machine
The offline assistant answers from Surveyor's help and federal survey references, with citations. An optional agent bridge lets an AI assistant you run work with Surveyor; it is off by default, and every change needs your confirmation.
- Runs without an internet connection
- A citation for every answer
- Agent bridge off by default, changes confirmed by you

Questions
About Surveyor.
Do I need an NVIDIA graphics card?
No. Surveyor draws with Vulkan 1.3 on NVIDIA or AMD graphics and does not use CUDA. AMD RDNA cards work when the driver exposes every Vulkan feature Surveyor needs.
Can I bring my Trimble and RealWorks jobs?
Yes. Surveyor imports Trimble .tdx projects and .tzf folders, and RealWorks .rwp projects with their station color and photospheres, as well as E57.
What can I deliver?
LAS 1.4, LAZ, E57, PGC2, LandXML 1.2, Shapefile, CSV, DXF linework, a project report and a zipped archive. Every delivery carries a manifest with checksums.
Does the assistant need the internet?
No. The built-in assistant runs on your machine and answers from Surveyor's help and bundled federal survey references, with citations.
