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, […]

Another problem is the difficulty of turning photogrammetrically derived point clouds into Digital Terrain Models. There is proprietary software that does this well (e.g. LasTools and others), but we sought a free and open source alternative and approach. Let’s visualize the problem.

This is a post about OpenDroneMap, an opensource project I am a maintainer for. ODM is a toolchain for post-processing drone imagery to create 3D and mapping products. It’s currently in beta and under pretty heavy development. If you’re interested in contributing to the project head over here. The Problem So for most of the […] via Viewing Sparse Point Clouds from OpenDroneMap — GeoKota Continue reading Viewing Sparse Point Clouds from OpenDroneMap — GeoKota
Great news on OpenDroneMap. We now have a branch that has MVS-Texturing integrated, thanks to continuing work by Spotscale, and of course continuing integration work by @dakotabenjamin. The MVS-Texturing branch isn’t fully tested yet, nor fully integrated, but the initial results are promising. MVS-Texturing itself handles the problems of choosing the best photos for a given facet on a textured model in order to do … Continue reading OpenDroneMap — texturing improvements

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, the revert to support GCC was really helpful for ensuring … Continue reading Taking Slices from LiDAR data: Part VI
I failed to make it to the Paris Code Sprint. It just wasn’t in the cards. But, my colleague Dakota and I sprinted anyway, with some help and feedback from the OpenDroneMap community. So, what did we do? Dakota did most of the work. He hacked away at the cmake branch of ODM, a branch set up by Edgar Riba to substantially improve the installation … Continue reading OpenDroneMap — Paris Code Sprint
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
