Modern 3D laser scanners capture millions of points per second to create dense point clouds, enabling surveyors to document complex sites accurately and share data via cloud platforms. This eBook by Trimble^® explores how scanning outperforms traditional methods in topographic surveys, BIM modeling and volume calculations across construction, forensics and urban planning.

In this eBook, you will learn how to:

• Capture comprehensive topographic data for site planning, including curbs, hydrants and terrain features that conventional surveys miss
• Integrate point clouds into BIM workflows for retrofit projects, ensuring as-built conditions match digital designs precisely
• Perform volume calculations on stockpiles or earthworks without on-site access, tracking material changes over time accurately
• Use self-leveling scanners with in-field registration to reduce setup time and eliminate return visits for data gaps
• Share interactive 3D models via web-based tools, allowing stakeholders to review scans on any device without specialized software
