Frequently AskedQuestions

No, Lidarvisor is fully cloud-based. There's nothing to download or install. Simply create an account and start processing your LiDAR data directly in your web browser. This means you can access your projects from any device with an internet connection.

Yes! Every new account includes 50 hectares of free processing. This allows you to test our automatic classification, DTM generation, and vectorization features with your own data before committing to a paid plan.

Lidarvisor accepts LAS, LAZ, and COPC.LAZ formats. These are standard point cloud formats generated from laser scans or photogrammetry. For more information on the LAS format, visit the ASPRS LAS specification page.

Import time depends on file size and your internet connection. For example, a 1 GB LAS file typically takes about 10 minutes.

Project creation happens in two stages:

1. Upload Stage: Your file is transferred to our servers. Please keep your browser open until upload completes.
2. Optimization Stage: Our system automatically optimizes the file for smooth 3D visualization. This runs in the background.

If we cannot automatically detect your file's coordinate system, you'll be prompted to select one from a list. You can search by name or EPSG code. Each country may have one or more official systems, plus international options are available.

Lidarvisor provides a complete set of tools for processing and visualizing LiDAR data:

• Automatic point cloud classification into 12+ classes: ground, vegetation, building, water, wire, transmission tower, pole, wall, hedge, solar panel, and roof objects
• Digital Terrain Model (DTM) generation with hillshaded exports in TIFF format
• Vectorization and export of contour lines, buildings, tree tops, and tree crowns to SHP or DXF formats
• Online 3D viewer for interactive visualization and collaboration
• Topographic map export for CAD software integration

Lidarvisor uses state-of-the-art machine learning algorithms trained on diverse LiDAR datasets. Classification accuracy typically exceeds 95% for common classes like ground and buildings. Results may vary depending on point cloud density, terrain complexity, and data quality. You can always review and refine classifications in the 3D viewer.

Processing time depends on your point cloud size and selected features (classification, rasterization, vectorization):

• A 10 ha point cloud typically takes a few minutes
• A 100 ha dataset may take up to an hour

The 3D viewer offers multiple visualization modes:

• Color (RGB): View points in their original colors
• Intensity: Visualize laser return intensity values
• Classification: Color-code points by class
• Elevation: Apply height-based coloring

Segmentation is the process of grouping point clouds into homogeneous regions with similar properties. For example, points are classified into categories like ground, vegetation, buildings, and water. This enables automated feature extraction and analysis.

Yes, Lidarvisor supports feet-based Coordinate Reference Systems (CRS). Our system automatically detects the unit type and handles all necessary conversions during processing.

Lidarvisor works best on modern browsers with WebGL support:

• Google Chrome (recommended)
• Mozilla Firefox
• Microsoft Edge
• Safari

If you experience any issues:

1. Check that you selected the correct EPSG code (a common cause of errors)
2. Verify your file format is LAS, LAZ, or COPC.LAZ
3. Ensure your file doesn't exceed size limits
