It’s a trite but we’ll earned pun. OSM Mali is amazing. I am in Bamako this week doing an OpenDroneMap workshop, and the community here is incredible. We just completed the first day of a two day workshop, working through some photogrammetry introductions, and on to some proper mapping tomorrow. For this round, we weren’t able to fly just yet, so we are working around … Continue reading Awesome Mali
In previous posts, we’ve scanned whole cities, cliff faces, down to small things like ukuleles and tiny pits to identify difficult to identify plants. This post goes in a slight different direction, doing a bit of a meta-scan of another kind of voucher: animal bones. I wanted to figure out what other interesting use cases there are for OpenDroneMap. For example, could we use it … Continue reading Scanning the samples with OpenDroneMap
In previous posts, we’ve scanned whole cities, cliff faces, down to small things like ukuleles. Such work is getting some to claim that the project needs renamed. Maybe… : Now, for a new problem space: plant identification. The background There are a few challenging plant groups to identify in the US. Among the ones I heard about in freshman biology: sedges (think: like grasses but … Continue reading Scanning the world with OpenDroneMap or Ne’er cast a cloot til Mey’s oot
In a previous post, I linked to a video I did on making good and affordable espresso. Now I link to a similar video on affordable mocha making. BTW, I have relegated my ROK grinder to backup duty: the 1ZPresso is now my goto, and better yet, my coffee is always freshly ground, no matter where I am. Yup. More on that later. Once again, … Continue reading Affordable Mocha
WebODM introduced support for plant health algorithms about a month ago. It was no secret that we concurrently started work to support TIFFs file inputs and multispectral cameras, both features that have been highly requested. We are excited to announce the release of ODM 0.9.8, which adds novel features as well as bringing significant improvements!… ODM 0.9.8 Adds Multispectral, 16bit TIFFs Support and Moar! — OpenDroneMap Continue reading ODM 0.9.8 Adds Multispectral, 16bit TIFFs Support and Moar! — OpenDroneMap
Introduction I had an interesting question recently at a workshop: “What parameters do you use for OpenDroneMap?” Now, OpenDroneMap has a lot of configurability, lots of different parameters, and it can be difficult to sift through to find the right parameters for your dataset and use case. That said, the defaults tend to work pretty… Choosing good OpenDroneMap parameters — OpenDroneMap Continue reading Choosing good OpenDroneMap parameters — OpenDroneMap
In previous posts in this series here and here II and here III here IV, we’ve worked through a surprising use case in OpenDroneMap: unreferenced imagery for general 3D reconstruction. Let us take this one step further toward 3D construction. If we have a model that we can georeference (✔️) and thus can do things like create contours (✔️) then maybe we can use these … Continue reading 3D Reconstructing… everything, part cinq: the beginnings of 3D construction
Let us explore a little more deeply the opportunity for drone photogrammetry for documenting deciduous forests. In previous posts, we explored exactly how, under the right conditions, we can see through leaf-off forest to the terrain below in ways that are quite favorable relative to techniques like lidar: But a side effect of this capacity, is resolution and reconstructions that reconstruct all of the standing … Continue reading Seeing the trees and the forest
Thanks to the tireless work of the folks behind the Zanzibar Mapping Initiative, I have been exploring the latest settings in OpenDroneMap for processing data over Stone Town. I managed to get some nice looking orthos from the dataset… https://smathermather.com/2020/01/15/stone-town-digital-surface-model/ After a few days of mapping the very small 🎸, let’s go back to a city scale, and back to Zanzibar. In the previous post, … Continue reading Stone Town Digital Surface Model — Part Two
In previous posts in this series here and here II and here III: , we’ve worked through a surprising use case in OpenDroneMap: unreferenced imagery for general 3D reconstruction. To get there, we eventually included ground control in the form of a coordinate system set by a builder’s square set in the scene. (Fair warning, I did find a bug in the automated calculation of … Continue reading 3D Reconstructing… everything, part quatre: a fully referenced ukulele
