LIS Visualization
LIS Visualization provides tools for creating 2D visualisations directly from point cloud data. The package supports orthographic and perspective projections as well as different rendering and shading approaches to highlight the geometry and structure of the captured scene. Typical applications include creating map-like views and high-resolution illustrations of LiDAR datasets, visualising buildings, terrain and vegetation, generating perspective views for reports and presentations, and producing specialised visualisations that make otherwise difficult-to-interpret 3D structures more accessible.
