Feb 08, Dear all, I have recenlty received a few tiles of LiDAR data that have scanned a large area with patches of landscape. I though that ReCap will be th eideal program to view them and manipulate. My main issue is that IO want to be able to see the gorund level scan removing the trees/dense vegetat Estimated Reading Time: 3 mins.

Is there any method to remove the vegetation from lidar data. Lidar. Civil 3D etc. but the contour is not so smooth. can u suggest me some method or tool which is helpful for smooth contour Estimated Reading Time: 5 mins. Automatic extraction of 3D objects from 3D LIDAR data has a very important role in the scientific community given its importance for modeling an urban scene, as it can significantly detection of 3D surfaces and kd-tree.
The octree structure is a data structure from tree type in which each node can have up to eight sub-nodes. The octree are most. There is no direct way of importing LIDAR data into Civil 3D. ReCap can import different point cloud files and produce RCP/RCS files which can be imported into Civil 3D.
Note: In previous versions of Civil 3D there was a direct way of creating surface from point cloud. This method was replaced with more efficient method involving ReCap. Point clouds are large data sets composed of 3D point data. Aerial LiDAR (Light Detection And Ranging) laser scanners are the most common instruments used to collect geographic point cloud data.
In the next dialog box, select filter Ground, and OK.
Geographic LiDAR data is most commonly available in LAS (LiDAR Aerial Survey) or bushmulching.bar) format. LAS is an industry standard file format defined by the American Society of Photogrammetry.

In the next dialog box, click OK and specify insertion point. 4. Zoom to see the point cloud.

Click Next Select Use existing surface border. Click Next Checkmark Percentage of points to bushmulching.bar 90% In the Display Manager, right-click a point cloud layer and select Filter Point Cloud. In the Filter Point Cloud Dialog Box, in the Filter By drop-down box, select the filter type you want to remove.
