I've been downloading whole tiles from OSIP for lidar surfaces. I've been using the grid files, and they work great. But, I don't really need an entire tile while working in my drawing, and I'd like to clip just my area of interest out of the tile. What is the fastest way to do this? These whole tiles are data hogs, and I fear they are slowing me down. Any info would be great.
I used to have a computer at my old job that wouldn't slow at all using this stuff, so I haven't had a reason to learn how to do this until now when i'm forced to work on a laptop.
Solved! Go to Solution.
I just cropped it using boundary under the surface definition. It looks great.
That just applies a "hide" boundary, and doesn't actually crop the surface.
Is there a better way of doing this? maybe "create cropped surface" is better? If so, I need more info. Thanks.
The command name is AECCCREATECROPSURFACE
Ribbon>Modify>Surface>Surface Tools>Create Cropped Surface
If you are in a hurry, upload somewhere the .LAS file + the .DXF clipping boundary, so that I could crop it by means of my opensource toolbox (una tantum...)
Is that aeccreatecropsurface command found in 2010? I don't have it under "surface tools."
Also, when I just type that command in, and then go to select my surface, the DEM surface doesn't appear in the list of surfaces that I can crop. I have two other surfaces in the project, and both of those do show up in the list though, so I know the command is working. It's just not working on the surface that I want it too.
I created this surface by using: surface/create surface from DEM
The data I used is from an .ADF file, not a .LAS file. I don't know if this matters?
You should be able to create a cropped surface with a data clip boundary as per the link below that will only read in the data you need. If you add a snapshot to the surface afterwards it won't need to re-read the source files when you open the file again but it will make the drawing's size larger.
