To create a surface from a point cloud
1 In the Display Manager, right-click a point cloud layer and select Create
Surface. The
Surface Manager (page 1898) appears.
2 To create a merge group, click Create Group in the
Create Surface dialog
box
(page 1895), then shift-click or control-click and drag the desired source
files into the group.
3 To filter the points used to create the surface, click the Filter field. The
Filter Point Cloud dialog box (page 1900) appears.
4 In the Filter By drop-down box, select one of the following filters:
■ Classification: if your point cloud data has been classified, you can
select which point classes to use when creating the surface. Shift-click
or control-click to select multiple classes.
■ Elevation: type the elevation ranges you want to use to create the
surface. Use hyphens to define ranges and commas to separate them;
for example, 150-200, 350-400, 1200-2000.
■ Intensity: you can use LiDAR intensity values to filter data. Use
hyphens to define ranges and commas to separate them; for example,
0.25-2.00, 3.50-4.00, 120.00-200.00.
■ Spatial: click the Locate on Map button to apply a spatial filter to your
point cloud. You can make a spatial selection using a circle, rectangle,
polygon, or proximity to an object on your map.
