3D Mapping & Modeling — point cloud and textured mesh of site

3D Mapping & Modeling

High-density point clouds, textured meshes and BIM-ready assets for design coordination, clash checks, quantities and as-built documentation.

Point Cloud (LAS/LAZ/E57) Textured Mesh (OBJ/FBX/GLB) Orthos • DSM/DTM BIM Handoff

From Reality Capture to Engineering-Ready 3D

We capture overlapping imagery (and optional LiDAR) with RTK/PPK alignment and ground control to generate accurate point clouds, textured meshes, and georeferenced orthomosaics. Outputs integrate smoothly into CAD, GIS and BIM workflows for planning, design, progress tracking and handover.

Deliverables include LAS/LAZ/E57 point clouds, OBJ/FBX/GLB meshes, GeoTIFF orthos, DSM/DTM, and CAD-ready contours—plus a clear QA/accuracy summary with checkpoints (RMSE).

  • Dense Point Clouds

    Clean, classified (on request), ready for sections, volumes and clash checks.

  • Textured Mesh Models

    Realistic surfaces for visualization, design context and coordination.

  • Orthos • DSM/DTM

    Georeferenced base maps and surfaces for take-offs and design.

  • BIM-Ready Handoff

    Clean alignment, units & CRS notes for modelers and coordination teams.

Capabilities

Rich spatial context that accelerates decisions and reduces rework.

Change Detection

Compare scans over time to quantify progress or deviations.

Volumetrics & Sections

Cut/fill, stockpiles and section profiles for earthworks and audits.

CAD / BIM Integrations

Clean CRS/units, layers and notes for smooth import and modeling.

Asset & Facade Models

Exterior detail for design context, retrofits and digital twins.

Linear/Corridor Mapping

Routes, RoW and structures with consistent control along the line.

Cloud/Web Viewer

Shareable links for stakeholders—no heavy software required.

Process

How We Build Your 3D

Control-first capture, rigorous QA, and clean handover.

Step 01

Scope & Control

Define AOI, outputs, CRS/units; plan GCP/checkpoints and flight grid.

Step 02

Capture

Autonomous flights; nadir + oblique imagery; LiDAR if requested.

Step 03

Processing & QA

Alignment, dense cloud, mesh/texture; checkpoints & RMSE summary.

Step 04

Deliverables

LAS/LAZ/E57, OBJ/FBX/GLB, GeoTIFF orthos, DSM/DTM, contours.

Step 05

Review

Web viewer link, notes and optional edits or feature extraction.

Step 06

Handover

Structured folders, metadata, CRS/units sheet and read-me.

Standards & Alignment

Outputs are georeferenced to your coordinate reference system (EPSG or site grid) with units and vertical datum clearly documented. We can include control/checkpoint tables, transformation notes, and layer naming conventions for CAD/BIM teams.

EPSG Codes Benchmarks Units & Datums Layer Standards

Equipment & Software

Professional drones and calibrated optics, tied to ground control—processed in industry-standard pipelines.

UAV w/ RTK/PPK

Nadir + oblique capture; consistent overlap and exposure control.

GCPs & Checkpoints

Ground control for reliable alignment and verified accuracy.

LiDAR (Optional)

Vegetation penetration and uniform density for complex sites.

Photogrammetry Suite

Metashape/Pix4D-equivalent workflow; clean exports with CRS metadata.

FAQ

Quick Answers

What you need to know about deliverables, accuracy and usage.

What accuracy can we expect?

With good control and checkpoints, 2–5 cm is typical. We include an RMSE table and map.

Can we open files in CAD/BIM tools?

Yes—LAS/LAZ/E57 and OBJ/FBX/GLB import into major CAD/BIM platforms; we also supply CRS and units notes.

Do you provide web sharing?

We can host or package a link for stakeholders to view orthos, clouds and meshes in a browser.

Can you classify or extract features?

Yes—ground/building/vegetation classification, breaklines and CAD layers are available as add-ons.
