The outputs
Five surfaces from one upload
All five generate in a single workflow, from the same classified point cloud.
Bare earth extraction
Digital Terrain Model (DTM)
See the ground beneath the clutter.
Ground points are isolated automatically from vegetation, buildings and noise to give a clean bare-earth surface, with hillshade colourization for instant terrain visualisation.
- Automatic ground classification removes above-ground features
- Hillshade reveals terrain relief at a glance
- Export as TIFF at your chosen resolution for GIS or CAD
Surface elevation
Digital Surface Model (DSM)
Capture everything above ground level.
The DSM preserves the highest elevation at each location, including buildings, trees and infrastructure, with a smooth colour gradient so structures and canopy patterns read immediately.
- Preserves all above-ground features for complete surface mapping
- Colour gradient highlights elevation differences
- Adjustable resolution, from urban detail to large-area mapping
Vegetation analysis
Canopy Height Model (CHM)
Measure vegetation height across the whole site.
The CHM is computed automatically by subtracting DTM from DSM, giving the true height of vegetation, buildings and structures above ground. Essential for forestry, corridor analysis and vegetation management.
- Automatic DTM/DSM subtraction gives true feature heights
- Colour gradient for quick canopy assessment
- Export raw CHM and the colourized visualization as separate TIFFs
Terrain analysis
Slope Map
Visualize terrain steepness in one click.
Slope is calculated straight from your DTM and colour-coded by intensity — built for construction planning, erosion analysis, drainage studies and accessibility assessment.
- Automatic slope calculation from DTM data
- Colour-coded visualization shows steepness at a glance
- Export slope data and the colourized map as separate TIFFs
3D mesh generation
Triangulated Irregular Network (TIN)
An accurate 3D mesh straight from the point cloud.
The TIN represents terrain as connected triangles that adapt to elevation change, giving a highly accurate 3D surface. Generated automatically, hillshaded for clarity, and exported for CAD.
- Adaptive triangulation follows natural terrain contours
- Hillshade reveals surface relief and features
- Export as TIFF, or as DXF, SHP and GeoJSON vectors
The difference
Why automated processing wins
Traditional terrain modeling takes hours of manual work. Lidarvisor does it in minutes.
Manual terrain modeling
- Manually filter and classify ground points
- Configure interpolation parameters for each output
- Separate workflows for DTM, DSM, CHM and slope
- Hours spent tweaking settings per dataset
- Expensive desktop licences
Lidarvisor automated processing
- Automatic ground classification, no parameters needed
- All five outputs in a single workflow
- Consistent, repeatable results across projects
- Processing finishes in minutes, not hours
- Cloud-based — nothing to install or maintain

Customer stories
Trusted by survey professionals worldwide
The powerful classification is the best feature. It saves a lot of time and money compared to manual classification or expensive solutions.
Emilio SegoviaHead of Operations, PDM 4 Cero
We saved a lot of time classifying our point clouds. Not only classified data, but also DEM, DSM, DXF exports we could use directly in our analysis software.
Marcel AertssenSurvey Analyst, SkySense UAV Solutions
Excellent software. Processing is extremely fast and highly accurate. Exemplary DSM and DTM outputs.
Theoharis PapadiamantisSurveying Engineer, Geodimetro
Lidarvisor has transformed my LiDAR post-processing workflow. The speed of results is impressive, all the useful data is correlated, and what I find exceptional is the DXF export function.
Carolina CollaroArchitect | University of Jaén, Spain
We used to outsource our LiDAR processing. With Lidarvisor, we brought it in-house and cut our costs significantly while keeping full control over the workflow.
Bodie Lloyd KiroriManaging Director | Geolens Engineering, Papua New Guinea
We tested Lidarvisor and achieved excellent results using a single platform. Previously, we needed up to three different programs to get similar results, which took us far more time and effort.

Questions
Frequently asked questions
What's the difference between DTM and DSM?
The DTM represents the bare earth surface with vegetation, buildings and other features removed. The DSM captures the highest point at each location, including everything above ground. Both are useful depending on the job: DTM for grading and earthwork, DSM for obstruction and visibility studies.
What resolution can I export at?
You choose the output resolution to match the project. Higher resolution gives more detail for small-area analysis; lower resolution suits large-area mapping where file size matters.
What formats are supported for export?
All raster outputs (DTM, DSM, CHM, slope) export as GeoTIFF, compatible with any GIS or CAD software. TIN exports as a raster TIFF or as vectors in DXF, Shapefile and GeoJSON.
How is the CHM calculated?
Automatically, by subtracting the DTM (ground surface) from the DSM (top surface). That gives the height of everything above ground level, including trees, buildings and other structures.
Do I need to configure any parameters?
No. Upload your LAS file and the system generates every terrain output without parameter configuration. The algorithms are tuned to work with any standard aerial LiDAR dataset.
