3D Scanning — Photogrammetry & LiDAR
High‑fidelity documentation for archaeological sites and historic‑built fabric: defensible geometry, georeferenced outputs, and submission‑ready packages.
Where it adds the most value
Use 3D capture when precision, repeatability, or mitigation documentation are required.
Pre‑construction record
Create a defensible baseline for sensitive features, structures, or landscapes before work begins.
Mitigation & closeout
HABS/HAER/HALS‑style documentation or photographic sets to support CEQA/Section 106 mitigation.
As‑built verification
Compare planned vs. constructed conditions; verify clearances, volumes, and impacts.
Fragile finds & features
Non‑contact capture for delicate artifacts, features, or areas with limited access.
Capture standards & workflow
We align to recognized specs and documentation guidelines so your record stands up to review.
Photogrammetry
- Dense image sets with cross‑angle coverage; coded targets or surveyed control as needed
- Scaled/geo‑referenced models (local grid or state plane); lens calibration documented
- Outputs: mesh (OBJ/PLY), textured models, orthophotos (GeoTIFF), and PDF plates
LiDAR / TLS
- Point clouds registered with surveyed control; classification & QA per project need
- Deliverables aligned to current USGS 3DEP Lidar Base Specification where applicable
- Outputs: LAS/LAZ (v1.4+), XYZ, intensity rasters, DSM/DTM, and plan/profile cuts
Typical deliverables
Right‑sized to your permit record—field to archive.
Data
- Point clouds (LAS/LAZ), meshes (OBJ/PLY), orthophotos (GeoTIFF)
- Geo packages (GPKG) & metadata (FGDC/ISO)
- Model viewer files for stakeholders
Documents
- Methods memo & QA/QC summary
- HABS/HAER‑style photo set and captions (as required)
- Plates: plans, sections, profiles, and key maps
Transmittals
- Submission‑ready packages (indices, readme, checksums)
- Archive prep (naming, formats, and media per agency)
- Integration with DPR 523 where applicable
