About this Course

The intent of these classes is to enable best practices of point cloud extraction, linework finalization & QA/QC as well as exporting procedures - all within a 3D CAD environment.

Suggested Skills & Prequisites

• Completion of a 2D CAD program or 2D Bentley program or equivalent knowledge
• Basic understanding of remote sensing technology and the generated data
• Access to prepared and qualified datasets via a Geospatial Administration (GA) group whom have completed relevant TopoDOT/TopoShare training
• Installation of the latest TopoDOT software with a compatible Bentley CONNECT product

Benefits of Training

• Everything is provided by our staff, and we come to you!
• Instructor-led (onsite/online)
• Our staff are domain experts in the entire TopoDOT process
• Accommodate small (8+ ppl) and large (20+) groups
• Customized training on your datasets
• System Agnostic - Multi platform (TLS, MLS, UAV/ALS)
• Our goal is to get your Extraction team production ready for HD Topographies
• Comprehensive, 5-day hands-on training to kick start your production team (zero to hero!)

Extracting Data with TopoDOT: Key Learning outcomes

• Navigate the 3D CAD environment, handle 3D point cloud data, and apply appropriate tools for digitization
• Extract infrastructure features, edit element geometry and attributes, and create an intelligent digital wireframe
• Verify wireframe accuracy and ensure data integrity
• Export work to an external platform or import to Bentley’s ORD terrain environment (Field Books)
