Re: Step in Rasterize function

I am sure you are aware that this is related to creating the DSM from the other question forum. I set a step of 0.0025 to maximize the resolution. When I change the scalar field property to "height range". Some of my points in various heights on each tree stem turn blue, indicating they ar...

Re: Step in Rasterize function

Is it possible then for a point in the middle of a tree to be recognized as a base point, therefore dropping it to the ground when creating a DSM ?

Step in Rasterize function

From my understanding, the step function is starting from the bottom and then working its way up to the top of the point cloud identifying each point it comes in contact with and saving its height value. If a point is located between a step, is the point given a height value of zero?

Re: DEM

Daniel,

That worked perfectly. The problem I believe I was having was not having the correct Active field selected. Thank you so much for working with me on this problem and I hope others find it useful as well. Cheers!

Re: DEM

My professor has allowed me to share a sub sample plot of the data with you. How do you want me to send it to you?

Re: DEM

Daniel,

I will ask my professor if that is alright to do, since it is not my data. If he agrees, I will be able to post the video tomorrow.

Re: DEM

Hello wpqjbzwm, I have used the plugin CSF. Separating the ground points and non-ground points is not the issue. As you can see in my other posts, the issue is my trees are being stretched. When I view the "side view" there are multiple sections of points on a z coordinate. All of these ar...

Re: Scalar Field

Yes and no. I am just wondering what it is and how cloudcompare is using scalar field values. I have heard that it is the intensity? Another question: with the RANSAC plugin, I read the wiki site on what the parameters do, but it does not specify what each of the advance parameters do. Could you ple...

Scalar Field

Would you please explain what the scalar field/value is and why it is important?

Re: DEM

These are my trees that I have projected. The lowest point of each tree are at the same level (Z coordinate), but the points that make up the tree have been stretched in the Z direction. I believe all my settings are correct. I will have to play with it some more. I was just wondering if you have se...
