This session introduces the fundamentals of working with water-body breaklines in LP360 to improve surface quality and generate more accurate DEMs. Presented at the LP360 User Conference, the session is led by Matthew Stevens, Technical Manager at GeoCue, and focuses on practical workflows for managing ponds and lakes.
The session demonstrates how to bring existing 2D water polygons into LP360, reproject LAZ data, and conflate those features to the point cloud to transform noisy water surfaces into clean, flat, enforced 3D breaklines. It also covers importing and managing PCTs, converting 2D features into 3D breaklines, enabling breakline enforcement, and validating results using contours and DEM exports.
Additional tips include working with WMS basemaps, project path variables, buffer class settings, and exporting surfaces for quality control. This session establishes the foundation for using water-body breaklines and prepares users for more advanced breakline workflows.
