I finally got PDAL properly compiled with Point Cloud Library (PCL) baked in. Word to the wise — CLANG is what the makers are using to compile. The PDAL crew were kind enough to revert the commit which broke GCC support, but why swim upstream? If you are compiling PDAL yourself, use CLANG. (Side note, […]

For this post, let’s combine the work in the last 4 posts in order to get a single pipeline for doing the following: Calculate relative height of LiDAR data Slice that data into bands of heights Load the data into a PostgreSQL/PostGIS/pgPointCloud database. Now, we can use parallel to make this run a little faster: Sadly, we can run into issues in running this in … Continue reading Taking Slices from LiDAR data: Part V
In PDAL, a pipeline file can be used to do a variety of operations. Within the following context, I think of a pipeline file like an ad hoc preferences file, where I can use an external command to iterate through the things I want to change, while holding constant everything else in the pipeline file. In my use case for this vignette, I’ll use the … Continue reading Taking Slices from LiDAR data: Part IV
forest_structure Borrowed from: http://irwantoshut.com Continuing my series on slicing LiDAR data in order to analyze a forest, one of the objectives of the current project is to understand the habitats that particular species of birds prefer. This will be accomplished using field info from breeding bird surveys combined with LiDAR data of forest structure to help predict what habitats are necessary for particular species of … Continue reading Taking Slices from LiDAR data: Part III
Wow. Thanks to my colleague Brandon Garman for this tip — Point Clouds in Sketchup. Mind you, I don’t think this is an inexpensive proposition, but a pretty cool looking tool: Continue reading Point Clouds in Sketchup?
Welp, my BASH skills could use some honing, but I’m just working on quick-and-dirty stuff for this series. PDAL as a utility is pretty interesting, so we’ll focus our learnings on PDAL. (Prior posts start here). I may have a build tutorial written for getting through the critical (as contrasted with minimal) parts of a PDAL build. I’m getting tired of running everything through docker. … Continue reading Taking slices from LiDAR data
