Hi Lindsay, If you still have problems with exporting the point cloud with real coordinates after the shift, before you export you can do this: 1. select the point cloud you want to export 2. click Edit from menu, select Edit global shift and scale click on the scroll of "Original" on top ...

Hi, Sorry it took me a while to answer and thanks for actually looking at those profiles. The very idea was to use t-lidar to actually map the overhang of the coastal cliffs and after extract transects that are processed automatically to get top and toe of the cliff and few other significant inflect...

Hi again, I could not - not sent you this new pointcloud that is a section for which it does not matter what value i am using for the max-edge, a big part of the profile is ignored. The pointcloud slice as usual is 0.1m thick and it obviously has some vegetation on top and the sides. I was thinking ...

Hi, Thanks so much. I would not say that the software is not doing what is coded to do. Since i do quite a bit a geomorphology and trying to automate different feature extraction i know how hard it is to have one code to answer to all cases, and i know some are just too different from the majority t...

Hi Daniel, Please let me know if you have more time to spend on my questions. I think somehow my pointcloud is kind of screwy .... somehow maybe the points should have been in a certain order or such .... i don't know. I have other slices of the pointcloud that behave even stranger than the one i po...

Hi Daniel, I just tried your new beta version and it works very nicely. I didn't realized my point cloud slices are considered "thick" since i choose 0.5 m for that param. I was afraid to make them thinner since my point cloud density is not constant over the survey. Besides, this is my fi...

Hi Daniel, Thanks for your prompt replay. I tried to use the debug mode and i cannot say that i understood it - unfortunately. If you still can bear with me, i will try to add some screen capture to explain. So - what exactly the "max_edge_length" param does? From the little explanation i ...

Hi again, The beta version worked beautifully for what i needed. Do you have any document in which you go in more details than the user manual on how you extract the polyline section and it's vertices from the slice of point cloud? Does the vertex on the polyline is the closest point from the point ...

Hi,

I am going to try the beta version right now. Thank you so much. I will let you know how i am getting along. This will be a tremendous help since all that data will go to some R scripts to extract some morphological features automatically.

Thanks, Monica

Hi, I am using the extract cloud sections along polylines in CC. I have hundreds of lines in a nice polyline shapefile. I can extract automatically on these lines the point cloud and the contour lines. I would like to export only the vertices of these contour section lines, not the 3d polylines. I s...
