Survey: Virtual Surveying

Menu: Survey

The Survey module in VisionLidar allows users to perform virtual surveying by measuring and vectorizing elements in the point cloud, just like traditional field instruments. The extracted vectorized data is stored in the project database and can be exported in multiple formats for further analysis in CAD, GIS, and LandXML-based applications.

✔ Supported Export Formats:
DXF, CSV, SHP, MID, KML, GeoJSON, and LandXML

Surveying Methods in VisionLidar

VisionLidar offers two main approaches for virtual surveying:

✔ Manual Surveying

Pick points and create lines manually from the point cloud.
Adjust point positioning precisely in 3D space.

✔ Virtual Surveying

Use automatic detection tools to speed up the vectorization process.
Identify cylinders, alignments, parcels, and other geometric structures.

Surveying Tools in VisionLidar

✔ Vision Database

Stores all vectorized survey data, including points, chains, and polylines.

✔ View Points and Chains

Allows users to visualize and manage extracted points and chains.

✔ Picking Points and Lines

Select individual points from the point cloud.
Create polylines to define boundaries, alignments, or survey features.

✔ Point and Chain Groups

Organize vectorized points into groups.
Classify and categorize surveyed data efficiently.

✔ Picking Cylinders

Automatically detect and vectorize cylindrical objects (e.g., utility poles, pipes).
Export extracted cylinders for BIM, CAD, or infrastructure planning.

✔ Alignments

Create and manage survey alignments for roads, railways, and infrastructure projects.
Define horizontal and vertical curves based on survey points.
