Can I calculate the cave volume with 3D lidar data in Cloud Compare?

Why did I never think of this? For context, I'm working on a fuel treatment project where we're trying to use LiDAR data quantify the density and volume of fine fuels removed from a forestry plot. Why did I never think to use the the C2C distance calculation?? And I had no idea about the multiscale model Comparison, I've gotta go try that!

Great tutorial! Thanks a lot! What I am a bit confused about is that you talk about UTCI but in fact you only have MRT as a result which is different to UTCI. Is there a way to create a UTCI map as well?

howdy! I have a simple display problem in grasshopper where the loaded E57 point cloud does not give a grayscale representation as seen in these videos, and the voxels are rather large, thus making it difficult to see detailed features. I'm on Rhino 7 and have tried version 2 and 3 of Volvox, both are the same.

amazing and much love from adl. thanks for your tutorials my friend❤❤

Hi, I am facing this "This tool has moved to UMEP for processing, available via the QGIS Plugin Manager. Visit our online manual for more information." when I try to go to SVF or Wall Height.

how can i use it in rhino 8?

i need to classification parameter .prm pleas

Can you please send the points file that you are working on in the video?

Thank you. I have a question. 1:00:28 Why the green roof is grass in surfaces (Land cover). If it is a building, shouldn't it be concrete or similar to the aother buildings?

Hi, while I click on the UMEP daily shadow pattern, I see that this tool has moved to UMEP for processing and I don't know how to open it. Please help

Did you ever make a tutorial on how to import shapefiles using OSM?

I totally loved this narration-free format, wow!

thanks for this tutorial. I got a Python error when I press the running model "TypeError: can only concatenate str (not "NoneType") to str". How to solve? I am sure the spatial data are correct.

Hi Carlos! Thank you so much for your work! Ive been learning a lot

Thank you Carlos

Can you use instead of the DEM the CDSM? Because in the CDSM are the buildings and trees already rasterized.

This tutorial is really good. However, I have a question about the shading device. Is there a way to analyze what happens under it? I can not find a way, so maybe you have found one. Thanks for all your tutorials, a real life saver!

so cool!!

Hi Carlos, thanks for the tutorial! I am beginner. My question is how I can assign materials to buildings is urbano. I want to analyse them in dragonfly plugin….

This is so interesting. Wondering if there is LiDAR for somewhere like Lerderderg in Victoria.

Hi Carlos, Do you know where I can find DTM data for WA and the whole australia?

الحقيقة سوف تصحح الباطل

hi love the explanation, will be using your method to complete my fyp. But I got a question, i know that there is no unit in cloud compare but heard you saying meters for the building, is this just an assumption or a method that you used to get it ? Thanks

Great Job! If I just take a temperature picture of a building's vertical facet and I have the 3D point cloud of such a building, can I attach the pixel value from a picture to the corresponding 3D pointcloud? Please attention, such a picture was taken from a certain angle. Hope to hear from you. Thanks.

Nothing happened when I added the SHP file Edit: looks like I had to update Urbano, but even when I did update it, it wasn't working. Had to uninstall Urbano from 'Control Panel' and install the newest version. Leaving this here incase anyone runs into this later on.

why does everyone press yes to lower points in las file to import into cloudcompare? what if i want all of the points? isnt it taking away from the quality of my scan?

You are the most knowledgeable source I've found on the internet regarding Docofossor. I'm currently experiencing difficulties when attempting to import my ASC files into Grasshopper while retaining their original origins. Unfortunately, they all end up at the coordinates 0,0,0, and I'm struggling to align my ASC file tiles correctly. I suspect the issue might be related to the "sx" and "sy" components of the plugin. Could you provide guidance on how to manipulate these settings to prevent the automatic placement of my ASC tile files at the origin point (0,0,0)? Thank you so much!

Thank you very much for this tutorial. Could you please explain the part when you selected the display range and then exported ground, sand, etc? Why did you choose those points ranges and how did you find out the exact display ranges for ground?

Hi, could please say what you did for both scans to be in the same survey grid?

Does anyone know of a plug-in that recreates this, now that Bison hasn't been updated for Rhino 7?

Hit here, Carlos! Thanks for your videos, they are highly useful. I was able to import my mesh (ImportXYZ > GridShift > GridRegion > GridMesh). I have made some modifications in the mesh within Rhino, as I find gives me greater flexibility instead of the terrain modifications on Docofossor. Now, I need to export this modified mesh to a XYZ again. However, I need the grid/mesh not to be shifted (therefore, I can't export directly from Rhino). Is there any way I can achieve this?

Thanks for this

Thank you for this. Very informative.

Hello Carlos. Thanks for the tutorial. I can't seem to import my Recap exported E57. Any idea how to fix this? I get the error "1. Solution exception:Object reference not set to an instance of an object."

can u please provide me link of these data it will really help in my research?

请问这个用的是什么版本？

can i get a link to download this data set?

How do you add rhe building heights when u already have it in your qgis file for buildings with the respective attribute height

How do you build the buildings from the shapefiles

Why do you need to rasterize a raster?

Hi Carlos, thanks for the video! Could you explain if the attribute table has to be named in a specific way for urbano to take the correct metadata? My attribute table has different height related to different building plots. But urbano extrudes them all at the same height. I checked the keys and values using deconstruct meta data and it seems the data is available but urbano doesn't use it when extruding building models.

you should edit your tutorial...

What is the easiest way to extrude this model in Grasshopper to have a closed mesh suitable for slicing and 3D printing?

Hello. Firstly thanks a lot for your videos, they are very instructive. I have a question: I would like to calculate the outdoor thermal comfort for a specific area in Athens, Greece. I have the DSM and DEM files, but not the CDSM. In the DSM file that I have, the trees and buildings are mixed. Is there a way that I can somehow create a CDSM file from that?

Hi Carlo, how can I solve the problem of the error that gives me as soon as I insert the last value of the Panels as soon as I finish connecting them to the "Download DEM and Build Terrain Mesh" component it turns red, I double-checked the limits in OpenStreetMap and I followed point by point importing the same region. The whole procedure of the Tutorial really instructive, I will never end up thanking you. I await instructions with confidence.

hi Carlos, not sure why, but Rhino doesn't pull up the data E57 data , any idea why that might be going on?

any way to include colored information from object material? i´m trying to create colored pointclouds from .fbx models. like transparent funiture. got many methods on creating pointcloud, yet nothing to match the color inside grasshopper.

hey, when I import the .asc file it is coming out to be flat terrain, even after applying all the input commands.

Great Tutorial! Exactly what i was looking for !👌
