Hello Sion,<br>
I was in Wales last month, I'd love to see some of the LiDAR! It's a<br>
beautiful country.<br>
<br>
To serve COPC local and/or remote (web server and cloud) I first downloaded<br>
and built potree according to the docs - see Getting Started at<br>
<a href="https://github.com/potree/potree" rel="noreferrer noreferrer" target="_blank">https://github.com/potree/potree</a><br>
As per the docs I just upload the Potree folder with all point clouds, the<br>
build directory, and your html files to a web server. You can optimize<br>
things by deleting a lot of content from the potree directory such as demo<br>
point clouds, shape files, example html, etc... I don't serve point clouds<br>
from the web server filesystem as the storage is cheaper in a cloud bucket.<br>
<br>
There is a copc.html example which you can use - just read through the<br>
source and adapt for either a local path or an http URL. I put my copc<br>
files in a google cloud bucket and then open the bucket up for CORS and<br>
HTTP.<br>
If you just want to try serving from the filesystem you could modify line<br>
57: var path = "../pointclouds/lion_takanawa.copc.laz"; and drop your copc<br>
file into the folder.<br>
<br>
Here's an example of one of my copc files - this is a large area (15,000+<br>
acres) but it's only the ground points.<br>
<a href="https://mappalachian.info/potree/viewer/copc2.html?r=https://storage.googleapis.com/mappalachian-entwine/lickstone/Lickstone_Surface_MergedSlope.copc.laz" rel="noreferrer noreferrer" target="_blank">https://mappalachian.info/potree/viewer/copc2.html?r=https://storage.googleapis.com/mappalachian-entwine/lickstone/Lickstone_Surface_MergedSlope.copc.laz</a>.<br>
It's 2.5GB. You can check the source of copc2.html to see what changes I<br>
made. I will say that for very large copc files you can really hurt a<br>
browser... (uses lots of memory) This example is about 250MB and it's much<br>
more responsive.<br>
<a href="https://mappalachian.info/potree/viewer/copc2.html?r=https://storage.googleapis.com/mappalachian-entwine/lickstone/NEPA_Unit_11_HAGDEM_EPSG3857.copc.laz" rel="noreferrer noreferrer" target="_blank">https://mappalachian.info/potree/viewer/copc2.html?r=https://storage.googleapis.com/mappalachian-entwine/lickstone/NEPA_Unit_11_HAGDEM_EPSG3857.copc.laz</a><br>
<br>
regards,<br>
Nick<br>
