MSF Canada Drone Day follow-up

Dirk’s MSF Canada Drone Day is officially the first blog post I have “re-blogged”. Please read: https://smathermather.wordpress.com/2015/07/13/msf-canada-drone-day/ or better yet here: http://dirkgorissen.com/2015/07/14/msf-canada-drone-day/ I had the pleasure of co-presenting with Dirk and Ivan, and the rest is well covered in Dirk’s post. It came together as an excellent day and I think you would be hard pressed to have had a better introduction to drones. The … Continue reading MSF Canada Drone Day follow-up

OpenAerialMap, OpenImageryNetwork, MapKnitter, OpenTerrain, and OpenDroneMap (cont. 1)

Citing my previous post, let’s move on to more specifics on my thoughts regarding the integration of OpenAerialMap, OpenDroneMap, and MapKnitter as projects. OpenDroneMap ❤ OpenAerialMap. OpenAerialMap will become a platform by which drone users can share their imagery under an open license. So, as the metadata spec for OpenAerialMap and OpenImageryNetwork matures, and as soon as a publicly available place for drone users to … Continue reading OpenAerialMap, OpenImageryNetwork, MapKnitter, OpenTerrain, and OpenDroneMap (cont. 1)

OpenAerialMap, OpenImageryNetwork, MapKnitter, OpenTerrain, and OpenDroneMap

This tweet: is the beginning of some fruitful discussion, I suspect. There are some really awesome projects gaining momentum. I’ll give an overview of them as best I am able. Let’s start with the one nearest and dearest to my heart (if you’ve been reading my blog, you can skip this part): OpenDroneMap. OpenDroneMap is an open source toolkit for processing drone, balloon, kite imagery … Continue reading OpenAerialMap, OpenImageryNetwork, MapKnitter, OpenTerrain, and OpenDroneMap

OpenDroneMap — GCP file format

Introduction: So much documentation to catch up on for OpenDroneMap. Probably the most important missing element is documenting the ground control point file format. This will be a file name gcp_list.txt to be placed in the root of the image directory that you are processing. Objective: The ground control point file associates locations in the input raw images with geographic positions, allowing for the output … Continue reading OpenDroneMap — GCP file format

OpenDroneMap — Now with animated GIFs

Ok. I confess, clickbait. OpenDroneMap won’t make the animated gifs for you. But come on! it can make the 3D models which you can view in Meshlab or where ever, and then create animated gifs. Ok ok. I promised animated gifs. These are from data contributed to our test dataset repo by  Aaron Racicot and Tomasz Nycz respectively.   Continue reading OpenDroneMap — Now with animated GIFs

OpenDroneMap — Orthophotos, textured mesh, ground control points, oh my!

Spotscale’s texturing, orthophotos, and ground control have landed on the main branch for OpenDroneMap. No docs written yet, but an orthophoto and properly oriented textured mesh will be autogenerated just by running it on data with GPS ephemeris. Documentation yet to come on using ground control points for balloons, kites, and lower end drones, but expect that early next week.   (edit: for the record, … Continue reading OpenDroneMap — Orthophotos, textured mesh, ground control points, oh my!

OpenDroneMap — Orthophotos and GCPs

No docs yet for orthophoto generation and the use of GCPs in OpenDroneMap, but for the early adopters, check out this branch of OpenDroneMap: https://github.com/OpenDroneMap/OpenDroneMap/tree/ortho-gcp The format of the GCP file is simple. The header line is a description of the coordinate system (nothing formal here). Subsequent lines are the X, Y & Z coordinate in your coordinate system, your associated pixel and line number … Continue reading OpenDroneMap — Orthophotos and GCPs
