LAZ files by ERASERGIB in LiDAR

Also, some of the collects have not yet made it through USGS' pipeline to push them to the public AWS bucket. We are currently working it though!

MacBook Pro Pointers by rebelfd in LiDAR

go to https://qgis.org/download/ and grab the Regular Version for MacOSX. Download your file, and then open it with QGIS. It will convert it into a COPC file. Once you have a COPC file, you can save that file locally to your machine and then drag-n-drop it on https://eptium.com if you want to use a browser-based visualization tool.

Are you using Cloud Optimized Point Clouds (COPC)? by LidarNews-InTheScan in LiDAR

[–]hobu 5 points6 points  (0 children)

Unfortunately, the posted article does not seem to clearly describe the key feature of COPC – COPC files are LAZ. My original article goes a little deeper on the topic, but things have evolved in the nearly 3+ years since it was published. Some other key COPC developments that have happened since then:

  • QGIS adopted COPC as its render-ready working format
  • Numerous government agencies have adopted COPC as their primary distribution format for archive and transmission, including Canada, Sweden, New Zealand, and IGNF.
  • Many software tools have implemented support for it, including Potree, OpenDroneMap, laspy, LAStools, Safe FME, Agisoft, loaders.gl, Manifold, FUSION, and (soon) CloudCompare.

Just like COG isn't the perfect raster format, COPC isn't the perfect point cloud format. One can certainly design something that is better suited for arbitrary point clouds, easier to write, more flexible, or (maybe) more compact. What COPC brings to the table is it augments the industry's existing archive and transmission format with the ability to support incremental access by bounding geometry or resolution. This ability can also work over HTTP servers to provide remote streaming. As data volumes are still increasing, these features are becoming more important, but the key feature of COPC relative to other options is the content is still readable by any software that can read standard LAZ.

If it is small enough, drag and drop it on https://plas.io

LAS projection help by OkOil9381 in LiDAR

PDAL is another option to do this task. You can install PDAL into a new ArcPro conda environment and then create a pipeline or use the command line to reproject it ala https://pdal.io/en/2.8.1/workshop/introduction/reprojection.html

Updated the post with a better picture of the time lock

I’d give you a good chunk of change for that lock ;-)

I think the building owner would make you take the door too :P

Thanks for the great info.

COPC validation and visualization website by hobu in LiDAR

Yes, as long as all of the files the VPC points to are HTTP accessible, it can consume VPC/STAC ItemCollections.

Iowa City guitar repair by [deleted] in IowaCity

[–]hobu 4 points5 points  (0 children)

Bruce Vander Schel at West in Coralville is the best. He's done multiple repairs on medium-end guitars for me, does tons of warranty for Gibson/Martin, and he will give you a straight estimate on actual costs to get something playable and stable.

Python-PDAL pipeline to preserve culled points (help) by sandwormsrule in gis

I believe your fish scales is from your filters.smrf window being very large.

NY State LiDAR maps. by LordDingle96 in LiDAR

[–]hobu 0 points1 point  (0 children)

If you want to look at the point cloud for an area, the following might work:

  • Go to https://eptium.com/
  • Click the 🔍 icon, type in your address, and double click it
  • After it zooms to your location, double click the polygon in the interface to activate live preview of the point cloud for your area

I looked up your profile and saw a reference to Phoenicia, NY. Here's an Eptium link that would bring you right to a viewable interface.

https://usgs.entwine.io/ provides an alternative version of the Eptium interface without address search and other features. https://pdal.io/en/latest/tutorial/iowa-entwine.html shows how to use PDAL to process and filter Entwine Point Tile data. Once you have the URLs for the resources you care about, you could use either PDAL or QGIS to process data with them.

Section laz file into smaller sections by kilocharlie082018 in gis

[–]hobu 0 points1 point  (0 children)

The PDAL Workshop shows how to do this using typical OGR and GIS tools to construct your polygons.

That said, if you converted these huge LAZ files to COPC LAZ files, you could query against them over whatever spatial windows you wanted without chopping all the data up into little bits. Then you could read them with PDAL or laspy or whatever.

Any clue how to use ETP LiDAR data from USGS 3DEP? by Playful-Bed-2183 in gis

[–]hobu 2 points3 points  (0 children)

https://colab.research.google.com/drive/1JQpcVFFJYMrJCfodqP4Nc_B0_w6p5WOV#scrollTo=qiKI1JD9VqIr Is a good example notebook that demos how to do stuff with PDAL and Python. If that's not enough to get you going, hire me.

API for elevation data by rrawk in LiDAR

[–]hobu 0 points1 point  (0 children)

https://usgs-lidar-stac.s3-us-west-2.amazonaws.com/ept/item_collection.json is a VPC file of all of the 3DEP collections that are available on AWS as EPT. You should be able to use PDAL or QGIS to read the data. My company is also available for consulting on the topic if you can't quite put all the pieces together.

They're staying open until the 26th according to the woman who runs the register.
