VRMesh Survey

An advanced solution for automatic point cloud classification and feature extraction. It classifies vegetation, building roofs, and ground points in LiDAR data or from UAV images. It detects building footprints, powerlines, poles, tree crowns, curbs and railways. It also helps you detect lines and extract pipes from point clouds.

Unlike traditional point cloud classification workflows that have to extract ground points first before classifying vegetation and buildings, the first fundamental step in VRMesh Survey is to detect vegetation. The major benefit of our workflow is its unique ability to automatically classify point clouds under extreme variations in terrain, no matter the data is gathered from steep slopes covered with dense vegetation or areas where there is very few ground points available.

Features and Benefits

  • Adjust LiDAR strips in a simple and fast way

  • Automatically extract ground points on steep slops

  • Automatically detect hidden man-made structures

  • Automatically extract building footprints from dense urban areas

  • Automatically extract powerlines/poles/tree crowns/railways

  • Quickly pick a line along a ridge, railway, powerline, road markings, etc.

  • Provide powerline detection and clearance analysis tools

  • Provide manual classification tools in a cross-section view

  • Generate grid surface and export to Esri ASCII Grids

  • Include Construction Module
