Survey: Virtual Surveying

Menu: Survey

Version française

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.

✔ Parcels

  • Extract and define land parcels from the point cloud.

  • Generate parcel boundaries for GIS and cadastral mapping.

✔ Measuring Distances

  • Measure horizontal, vertical, and 3D distances between points.

  • Display accurate measurements for survey analysis.

✔ Measuring Angles

  • Calculate angles between vectors or surfaces.

  • Useful for engineering and structural analysis.

✔ Measurement Kit

  • A comprehensive toolset for distance, area, and volume calculations.

  • Supports multi-point selections for complex survey tasks.

✔ Create Polyline

  • Generate vector polylines directly from the surveyed data.

  • Used for road layouts, utility mapping, and architectural planning.

✔ Corridors

  • Define corridors along surveyed alignments.

  • Export corridor data for roadway, railway, and infrastructure planning.
