ODM 0.9.8 Adds Multispectral, 16bit TIFFs Support and Moar! — OpenDroneMap

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

Seeing the trees and the forest

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

Affordable Espresso

So, I did a thing. I created my first personal internet video. It’s about coffee. Well, more specifically about espresso, which like Turkish, Arabic, and Ethiopian coffee types is not just merely coffee, but somehow something much more. Not content with throwing it up on YouTube, I put it on PeerTube: With more than 100 000 hosted videos, viewed more than 6 millions times and … Continue reading Affordable Espresso

Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game (part 2)

In the beginning In a previous blog post, we explored how we can quite effectively derive terrain models using drones over deciduous, winter scenes. We ran into some limitations in the quality of the terrain model: the challenge was removing the unwanted features (things like tree trunks) while retaining wanted features (large rock features). I concluded the post thusly: For our use case, however, we … Continue reading Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game (part 2)

Mapping the ephemeral

One of my favorite aspects of drone mapping is, since it is 1) under our personal control 2) high resolution and 3) can collect data even when it’s cloudy, it’s possible to observe and document ephemeral phenomena that otherwise might not be captured by satellite or manned aircraft imagery. To that end we mapped lake ice yesterday. We have been flying a series of videos … Continue reading Mapping the ephemeral

Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game

LiDAR and photogrammetric point clouds If we want to understand terrain, we have a pricey solution and an inexpensive solution. For a pricey and well-loved solution, LiDAR is the tool of choice. It is synoptic, active (and therefore usable day or night), increasingly affordable (but still quite expensive), and works around even thick and tall evergreen vegetation (check out Oregon’s LiDAR specifications as compared with … Continue reading Reconstructing cliffs in OpenDroneMap, or how to beat LiDAR at its own game

Optimizing flight planning for calibration (or Self Calibration of Cameras from Drone Flights, part 4)

The problem with typical approaches to scaling up data collection just take a standard flight path and do it a lot of times. This compounds error over the space it’s done in, which with really large data sets results in a notable bowl in the data due to incorrect lens calibration estimates. There are several fixes: If possible, fly with a fixed lens like Sensefly’s … Continue reading Optimizing flight planning for calibration (or Self Calibration of Cameras from Drone Flights, part 4)

Reconstructing stream corridors in OpenDroneMap

In October of 2017, a few collegues and I walked down West Creek, in Parma, Ohio to do some prospective mapping of the stream corridor. The hope was this: that by taking a sequence of photos from within the stream, we could use photogrammetry to reconstruct the corridor and ultimately model water flow through the same corridor. Knowing the the reconstruction of this complex physical … Continue reading Reconstructing stream corridors in OpenDroneMap

Kole Wetland Canal Mapping with ClusterODM

My friends and collegues at International Center for Free and Open Source Software in Kerala, India have done a pretty interesting and massive mapping initiative over Thrissur Kole Wetlands. The wetlands are a massive 30,000+ acre area that are both important to wildlife and provide rice production. Suman Rajan, Asish Abraham, and Deepthi Patric (left to right in image below) mapped 9000 acres of it. … Continue reading Kole Wetland Canal Mapping with ClusterODM

Upcoming improvements to OpenDroneMap — Better everything.

Problem Overview: One of the greatest challenges with OpenDroneMap (ODM) is getting great results out of sparse data. I used to describe this as getting good data out of mediocre inputs, but this isn’t a fair descriptor, and here I’ll make a public apology: just because I have the time to fly with lots of overlap most of the time doesn’t mean it should be … Continue reading Upcoming improvements to OpenDroneMap — Better everything.
