A collection of new techniques are presented for generalizing bathymetry in the chart compilation workflows in BASE Editor. Two new methods for generalizing elevation surface models and a new safe-side contour smoothing method are available. These can be used to produce hydrographically-safe results, pushing contours to the deeper water.
A new Thin Points process is also included that can be used for general purpose point thinning or to produce a shoal-biased point cloud suitable for chart compilation. The new point thinning and smoothing techniques can be used in isolation or together with other tools in the cartographic bathymetric feature compilation workflow to produce the best results.
A new workflow for editing classification values on Lidar point clouds is now available in BASE Editor. The new tools are available in the Subset Editor, allowing area based QC and cleaning processes to be followed.
The new Lidar workflow tools allow for quick, toggle on/off visibility, and colouring based on classification as well as editing of flags and classification attributes for points. New classifications can be added or removed. Cleaned and classified clouds can easily be filtered based on classification and modeled as elevation surface models, exported back out to LAS format or uploaded into BDB Server as appropriate.
Improved visualization and performance when working with point clouds in the 3D view. In particular, points can now be visualized with new geometry styles, such as ‘Oriented Splats’, which allow the points to be experienced as a seamless and shaded surface model. As well, the user has new options to go into a Pan Control mode to reposition data in the 3D view. This and other modes are available in the 3D section of the Options settings.
To facilitate the creation of process models for completing complex or repetitive tasks, a number of sample process models are now included in the installation. Of particular interest will be process models for bENC and S-102 Bathymetric Surface creation. These files are found under C:\ProgramData\CARIS\BASEEditor\4.4\SampleData\
