FAQ

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

• Automatic point cloud classification into ground, vegetation, building, water, wire, transmission tower, pole, wall, hedge, solar panel, and roof object.

• Generation of Digital Terrain Models (DTM) and hillshaded DTMs in TIFF format.

• Vectorization and export of key features such as grids, contour lines, buildings, tree tops, and tree crowns to SHP or DXF formats.

• Online 3D viewer with the ability to share your project via a link for easy collaboration.

• Export of topographic maps in SHP or DXF formats for seamless integration into CAD software.

The accepted format is the LAS format. To create a project on Lidarvisor, you must import a point cloud in LAS format. This is a data format commonly used to represent a point cloud generated from a laser (LASer) scan or generated through photogrammetry. Many software packages allow you to export to this data format (e.g., DJI Terra, Terrascan, Global Mapper, Metashape, Pix4D…). The LAZ format (compressed LAS) is not accepted at the moment.

For more information on the LAS format, you can visit this site: https://www.asprs.org/divisions-committees/lidar-division/laser-las-file-format-exchange-activities

The time required to import your LAS file depends on both the file size and your internet connection speed. For example, a 1 GB LAS file may take approximately 10 minutes to complete the import process.

Project creation happens in two stages:

1. Upload Stage: During this phase, the LAS file is transferred from your computer to the server. Please do not close or leave Lidarvisor until the upload is fully completed, as this will interrupt the process.

2. Optimization Stage: Once the upload is finished, the system automatically optimizes the file for smooth 3D visualization on the web. This step is handled in the background and doesn’t require any further action from you.

If you encounter a technical problem, such as a file error, you can contact support by email using the contact form on the side, and you will receive a response within 24 hours. A common issue is selecting the wrong EPSG code, which can cause errors during the optimization process.

As a freemium user, you can import LAS files up to 2 GB each, with a total storage limit of 2 GB.
With a paid account, the per-file upload limit increases to 10 GB, allowing you to work with larger datasets.

If you need to import files beyond these limits, feel free to contact our sales team using the contact form on the side.

When your project is created, you can share it with your colleagues. To do this, once logged in to Lidarvisor, you need to click the “Share” button (at the top right) and copy the project access link. People with this link will be able to view your project, including the point clouds and digital models that make up the project. However, they will not be able to download the files. This is read-only consultation.

To suggest an improvement, we invite you to contact the support service, using the contact form on the side. All suggestions are welcome!

On Lidarvisor, we offer the following visualization modes: color (RGB), intensity, class, and elevation. By expanding the point cloud (in the left sidebar), you can also filter points by class. The represented classes are the standard classes of the LAS format.

When importing your LAS file, if we cannot detect the coordinate system of the file, you are then asked to select the coordinate system from a list provided. Each country may have one or more official systems. In addition, there are also international systems. The search can be done by text or directly via the EPSG code if you know it.

Segmentation is the process of grouping point clouds into multiple homogeneous regions with similar properties as ground, vegetation, building…
