LiDAR Processing & Point Cloud Classification
Unclassified LiDAR is only as good as the processing behind it. Don't let massive point clouds tie up your high-cost engineering workstations — we act as your dedicated geospatial back-office, turning raw spatial scans into clean, structured terrain models and 3D surface assets.
Ground filtering & bare-earth extraction
Algorithmic and manual classification to remove vegetation, structures, vehicles, and noise from complex terrain.
Feature & infrastructure classification
Categorization of buildings, powerlines, utility poles, bridge decks, and dense canopy.
DTM & DSM generation
Precision surface modeling — digital terrain and surface models built for civil design and hydrological analysis.
3D mesh & structure modeling
High-density spatial meshes for structural visualization, slope stability, and volume assessment.
Supported output formats
| Point clouds | .LAS · .LAZ · .E57 · .XYZ · .RCP |

Drone Mapping & Aerial Photogrammetry
Flying the drone is only half the battle. Processing millions of pixels, aligning ground control, and extracting vector features takes serious compute and specialized spatial expertise. We handle the heavy digital lift so your team delivers faster.
High-resolution orthomosaic mapping
Seamless, color-corrected, orthorectified imagery tied to your local coordinate system — true-scale, with zero perspective distortion. Repeat-flight processing tracks site progress with pixel-level alignment.
Topographic & contour mapping
Custom contour intervals (0.5 ft, 1 ft, or metric) optimized for Civil 3D and MicroStation, over bare-earth DTMs. Breaklines drafted at ridges, valleys, retaining walls, and curb lines to keep the surface honest.
Planimetric feature extraction
Manholes, catch basins, utility poles, signage, valve covers, building footprints, pavement edges, driveways, curbs, gutters, fences, tree canopy, and water-body edges — digitized into layered CAD vectors.
Volumetric & stockpile analysis
Cut/fill heatmaps against design grades or prior flights, stockpile tonnage without putting crews in hazardous zones, and high-density surface tracking for mining faces and embankments.
Deliverable formats
| Orthomosaic & raster | GeoTIFF · .ECW · high-res .JPEG / .PNG |
|---|---|
| CAD vectors & contours | .DWG (Civil 3D / AutoCAD) · .DXF · .DGN (MicroStation) |
| 3D surfaces & mesh | .OBJ · .PLY · .FBX · .TIF elevation maps |
| GIS layers | .SHP · GeoPackage · .KML / .KMZ |
| Volumetric audits | .PDF reports with 3D cross-sections |
We validate check shots, inspect tie points, and verify breaklines rather than pushing buttons on automated software. Standard datasets are processed within 24 to 48 hours.

From raw acreage to shovel-ready civil plans — complete site engineering layout and drafting support for civil engineers and land developers.
Site layout & master planning
Building footprints, parking layouts, access roads, curb radii, and pedestrian access routes.
Grading & drainage design
Proposed surface modeling, 3D grading plans, swale alignment, retention/detention pond design, and slope analysis.
Earthwork & volume calculations

Utility infrastructure design
Stormwater network modeling, sanitary sewer collection layout, water main distribution, and utility profiles.
Roadway & pavement design
Horizontal and vertical alignment, cross-sections, plan and profile sheets, and intersection details.
Every sheet passes a QA/QC review by a senior CAD operator checking boundary closure, dimensioning, text placement, and sheet formatting before delivery.

Client Feedback
What Engineering Leaders Say
SANMUD absorbed our point-cloud backlog and returned classified deliverables in half our internal turnaround. They operate like an extension of our own drafting floor.
The scan-to-BIM accuracy was audit-clean on first delivery. Clash detection was already run before the model reached us. That is rare.
Predictable pricing, standardized layers, and a QA index we can put in front of our clients. It de-risked our subcontracting entirely.
