Surface Lidar Make

Creates a lidar .LAZ file from points on entities (including surfaces). The first interaction is the designation of the output file to create. After that you will be prompted for objects or a surface, details on each below.

Keyboard Command: SurLidMak

• Objects: Prompts for a selection set of objects, either 2.5D or elevated polylines, etc. All the vertices of the objects will be written to the output file, including points along curves, etc.
• TinSurface: Prompts for selection of a TinSurface, then an interval, the default being 0.0. When 0.0 is used, all the vertices of the TinSurface will be written to the output file. If anything above 0.0 is used, the surface is sampled (see below).
• GridSurface: Prompts for selection of a GridSurface, then an interval, the default being 0.0. When 0.0 is used, all the nodes intersection of the GridSurface will be written to the output file. If anything above 0.0 is used, the surface is sampled (see below).

Notes:

• When sampling takes place, the surfaces bounds are determined, then the tool begins sampling in the lower left corner, then goes along the bottom row at the specified interval to the lower right. Then rows accumulate up the surface on the interval, again sampling across at the interval. This creates a .LAZ point file that resembles a grid of points, although the grid interval does not have to coincide with any existing grid.
