Managing LiDAR Data
The Point Cloud Manager
After you have brought files into the
Point Cloud Manager (page 1897), you can
gather them into merge groups, specify coordinate systems for your point
cloud data store files, and apply filters to control what data will be included
in their associated point cloud data store.
When you create a Merge Group, AutoCAD Map 3D assigns several LiDAR
source files to a single point cloud data store. You might want to create a
merge group to apply a spatial filter across several source files, for example.
You can also create a group of point clouds in Display Manager that uses
separate point cloud data stores for each LiDAR source file.
AutoCAD Map 3D assigns a default name and save location for the point cloud
data store index file. You can view the default output name and location in
the Output field in the Point Cloud Manager.
In most cases, AutoCAD Map 3D automatically determines the coordinate
system of your LiDAR data based on information in the LAS file and displays
it in the Coordinate System field of the Point Cloud Manager. When you
create a point cloud data store, AutoCAD Map 3D assigns the source coordinate
system to it by default. If you are using an ASCII data source, or if AutoCAD
Map 3D cannot determine the appropriate coordinate system, you can specify
the coordinate system for your point cloud data store in this field.
