Advanced features

Everything under the hood.

The full capability list, for the engineers and surveyors on your team who want the details.

Accuracy & verification

Ground control checkpoint QA: Import RTK rover shots by paste or CSV, see each one pinned on the scan, and get per-point residuals: known elevation vs. scanned surface, delta, and pass/fail against a tolerance you set. Reports vertical RMSE and flags when the dataset meets 3 cm vertical or better.
Accuracy statement in reports: Checkpoint results attach to generated reports, so deliverables carry their own proof.
True coordinate systems: Every scan lives in its real projection (state plane or UTM, EPSG-coded). Coordinates, exports, and measurements are all in the native CRS, not arbitrary local space.
Exact unit handling: One-click toggle between US survey feet and meters. Measurements convert exactly and the underlying data is never resampled.

Point: Drop a pin, get easting, northing, and elevation.
Distance: 3D slope length, horizontal distance, elevation change, and grade percentage along a multi-point path.
Area: Planimetric area plus perimeter for any polygon.
Height: Two-click elevation difference with horizontal offset.
Angle: Three-point angle measurement.
Volume / stockpile: Outline a pile, get net volume, cut, fill, footprint area, and the base-plane method used (lowest vertex or least-squares mean plane), with sampled-cell counts for auditability.
Automatic stockpile detection: One click outlines every pile toe on the site and computes each volume.
Set on ground: Snap any measurement's points to the terrain surface.
Pinned notes: Annotations anchored to real locations in the scan, with fly-to.

Custom contours: Generated on demand at any interval, with elevation labels, configurable colors and line weights, and the option to restrict them to a drawn analysis area.
Water flow simulation: Set a rainfall depth and watch animated streamlines and directional arrows trace drainage across the site, with ponding-depth visualization.
Basin / low-point report: A table of every depression: location, depth, and ponding volume.
Slope heatmap: Instant steepness overlay across the whole site.
Elevation profile: Cut a section line and get the ground profile along it.
Elevation color modes: Height ramp, intensity, classification, and bare-earth views alongside true-color RGB.
Analysis areas: Draw a polygon to scope contours and hydrology to just the region that matters.

Design surface overlay: Import a design (DXF 3D faces or LandXML TIN) and compute cut and fill to design directly against the scan.
Change detection: Compare two scans of the same site and see the differences as a heatmap: what was added, removed, or regraded between visits.
CAD/GIS overlays: Drape DWG (server-converted), DXF, KML, and GeoJSON over the scan, with an alignment tool for fine-tuning fit.

DEM GeoTIFF: Float32 elevation model that opens at true coordinates in QGIS, ArcGIS, and Civil 3D.
LandXML 1.2 TIN: Imports as a surface in Civil 3D, Trimble Business Center, and Carlson.
PNEZD point grid CSV: The format survey crews actually use: point, northing, easting, elevation, description.
Measurement exports: CSV, DXF (CAD, native CRS), GeoJSON (GIS), and KML (Google Earth and Land id).
Original source files: Clients can download the raw deliverables you attach to the project.

Massive point clouds, streamed: 160-million-point scans open in seconds in a browser. Detail streams in as you move, served from a global CDN.
Three data types in one viewer: Classified point clouds, textured 3D meshes, and Gaussian-splat photorealistic captures, plus orthomosaic and DTM drapes.
Works on phones and tablets: Adaptive rendering tunes itself to the device, with automatic recovery if the mobile GPU taps out.
Compass and plan view: An always-on north indicator (click to face grid north) and one-click top-down view.
Site tours: Record a camera flythrough, replay it live for a client, or export it as a shareable video.
Saved views: Bookmark camera angles anyone can jump back to.
Site statistics: Scanned footprint, building and vegetation coverage, elevation range, and average terrain slope computed per scan.
Snapshot export: One-click high-res PNG of the current view.

Controlled share links: Per-link control over which scans are visible and whether measurements and notes show. Presentation mode is view-only.
Email-verified access codes: Clients enter a project code plus a one-time passcode sent to a pre-authorized email. Unknown emails are denied.
Project-scoped everything: Measurements, notes, checkpoints, and share restrictions are enforced server-side per project and per layer.
