Digging a little deeper. Ran the chipper on a smaller number of points and then am doing a little hacking to get height per chip (if you start to get lost, go to Paul Ramsey’s tutorial). Here’s my pipeline file. Note the small chipper size– 20 points per chip. Easy enough to load (though slow for the sake of the chip size): Now we can … Continue reading LiDAR and pointcloud extension pt 3
As much for my edification as anyones: Want to get at just a few points within the pointcloud extension? A with query will get you there: Continue reading LiDAR and pointcloud extension pt 2
Paul Ramsey has a great tutorial on using the pointcloud extension with PostgreSQL / PostGIS: http://workshops.boundlessgeo.com/tutorial-lidar/ You can get point cloud and all that goodness running a variety of ways. Probably the easiest is to download OpenGeo Suite from Boundless: http://boundlessgeo.com/solutions/opengeo-suite/download/ If you are an Ubuntu user, try a docker instance to run PostGIS with PDAL, pointcloud, etc in a container: https://github.com/vpicavet/docker-pggis Also, I’m working … Continue reading LiDAR and pointcloud extension
This year’s FOSS4G is in Portland, September 8th through the 14th. It should be a great conference. Related and relavent: yours truly will keynote and offer a half day workshop in PostGIS at FOSS4G Korea, 2014. I cannot put into words how excited I am. Sanghee, representative of OSGeo Korean Chapter put the relevant info on FOSS4G Korea 2014 succinctly: “FOSS4G Korea 2014 will be … Continue reading FOSS4G Korea 2014
Docker. See: https://github.com/vpicavet/docker-pggis for a quick and easy Docker running PostGIS. Understand, this isn’t production ready (the connection permissions make my teeth hurt a little) but, so nice to have a one stop shop for postgis, pgrouting, and pointcloud. Now I may have to write blog posts on pointcloud. Point cloud didn’t get in the PostGIS Cookbook because it was too hard to build. I … Continue reading The easiest way to get PostGIS and friends running:
I’m amused that on this day, I have zero hits from the US on my blog. Nice job paying attention to Mother’s Day, all: Continue reading Mother’s Day — sacred/
In my previous post on Getting Bundler and friends running, I suggested how to modify an existing script to get Bundler and other structure from motion parts/pieces up and running. Here’s my follow up. Install Vagrant and VirtualBox. Download (or clone) this repo: https://github.com/OpenDroneMap/odm-vagrant Navigate into the cloned or unzipped directory (on the command line), run vagrant up Go have a cup of coffee. Come … Continue reading Getting Bundler and friends running — part deux
Anyone who has jumped down the rabbit hole of computer vision has run into dependency h*ll getting software to run. I jumped down that hole again today with great success that I don’t want to forget (these directions are for Ubuntu, fyi). First, clone BundlerTools: https://github.com/qwesda/BundlerTools This will download and compile (almost) everything for you, which is a wonderful thing. The one exception is graclus. … Continue reading Getting Bundler and friends running
I have been contemplating all sorts of varied uses of Structure from Motion techniques. One of those outputs, in addition to using sUAVs (drones) is just to orthorectify and generate 3D meshes from ordinary photos. This has really great potential for linear assets like streams and rivers, trails and roads. We’ll have to being to contemplate how we’ll use (and summarize!) the incredible amount of … Continue reading Inventorying linear assets– really high resolution orthos
