Frequently asked
The basics on our services, deliverables, and how we work. Don’t see your question? Ask us directly.
What’s the difference between photogrammetry and LiDAR?
Photogrammetry builds 3D measurements from many overlapping photographs — it excels at true-color surfaces and orthophotos. LiDAR fires laser pulses that can reach the ground through gaps in vegetation, capturing bare earth that photos alone can’t see. CCAM offers both, and often combines them on a single project.
Should I choose UAV LiDAR or manned aerial mapping?
It depends on the size of the area and the detail you need. Drones are ideal for focused, high-resolution capture of a site or corridor; our manned UltraCam-X camera is built for large-area, state-grade coverage. For large vegetated areas we can fly a hybrid mission that pairs imagery with LiDAR. Tell us the site and we’ll recommend the right fit.
What deliverable formats do you provide?
Point clouds in LAS/LAZ, orthophotos in GeoTIFF, surfaces and linework in DWG/DXF (Civil 3D-ready), terrain and contour products, KMZ, and PDF map sheets — matched to how your team works.
Do your surface models import into Civil 3D?
Yes. We deliver TIN surfaces, breaklines, and contours that drop directly into Civil 3D and AutoCAD, so your engineers can start designing without reprocessing the data.
What’s the difference between a DTM and a DSM?
A DTM (digital terrain model) is the bare-earth surface with buildings and vegetation removed. A DSM (digital surface model) keeps the first surface — rooftops, tree canopy, and structures. Many projects use both.
Can LiDAR really capture the ground under trees?
In vegetated terrain, a portion of each laser pulse reaches the ground through gaps in the canopy, so LiDAR can reconstruct bare earth where photography only sees treetops. It’s one of the main reasons to choose LiDAR for forestry, corridors, and brushy sites.
What is 3D reality capture?
It’s turning real-world aerial capture into a 3D model you can work with — colorized point clouds and reality meshes for digital twins, visualization, measurement, and design coordination.
How accurate is the data?
We deliver to the accuracy your project specifies and work to the mapping-accuracy standards of ASPRS and ACSM. Tell us the tolerance your application needs and we’ll plan the capture to meet it.
What areas do you serve?
We’re based in San Luis Obispo on California’s Central Coast, with statewide capability.
