CAD Drawings from Aerial Scanned Point Cloud Data for Surface Plan

Project

Published by:
Datasheet
Company: Hitech BIM Services
Location: Ahmedabad, India
Year of the project: 2017
Description

Client Profile:

Drone Solution and Data Consultant

Industry: 

Infrastructure Development 

Location: 

France

Software Used:

AutoCAD, Global Mapper, FME, Mensura, Google Earth

Input Received: 

Configuration, DSM, Log, Model, Acquisition Details, Ortho-photography, Point Cloud Data, Slopes Degree

Challenges:

  • Understanding the uneven slope, road subbase and site topography in a short period from the scanned data beforehand the CAD conversion begins.
  • Steep banks, overgrown areas, and other complex topography demanded skillful interpretation to deliver accurate engineering CAD drawing and placement of safety berms.
  • For the safety operations, interpretation of fissures and cracks in the scanned data before preparation of the surface plan.

Solutions:

  • The project engineers at Hitech studied the aerial scanned point cloud data, acquisition details, and Ortho-photography, and converted them using point cloud data into engineering CAD drawings for a surface plan such as haul road, safety berm, quarry face and most important computation of Stockpiles. 
  • They also prepared detailed excel reports for mining site data analysis and project documentation for the lifecycle of a mine.
