Global Mapper LiDAR Module v18.2 Now Features Hydro-Flattening Capability
Blue Marble Geographics has recently announced the release of Global Mapper version 18.2, the latest edition of the Module includes support for hydro-flattening from 3D lines or polygons when creating a terrain surface. In this process, any line or area feature that includes a single or per-vertex elevation value will create a localized terrain surface that overrides the z-values in the corresponding LiDAR points. This ensures that water bodies are accurately rendered as flattened surfaces and streams follow downhill, ignoring any elevation anomalies in the point cloud. This breakline function can also be applied to man-made features such as road center lines and curbs.
When rendering LiDAR data using version 18.2 of the LiDAR Module, a visual distinction can now be applied based on the withheld, overlap, and model key point flags. LiDAR Module scripting options now include a new command for performing LiDAR to control point comparison and adjustment, mirroring the LiDAR QC function in the software.
The Global Mapper LiDAR Module is an optional add-on to the software providing numerous advanced point cloud management and analysis tools. These include automatic ground point detection and classification; feature extraction; cross-sectional viewing and point editing; LiDAR QC; significantly faster terrain surface generation; and much more.
Current users of Global Mapper can activate a free two-week trial of the LiDAR Module from the Module/Extension License Manager within the software. To download a trial of the standard version of Global Mapper, visit: www.bluemarblegeo.com/products/global-mapper.php
