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

OpenDroneMap — Orthophotos and Textured Mesh (Habitats)

ODM shows some promise in mapping out microhabitats as on display with Michele Tobias & Alex Mandel’s dataset of hot air balloon derived images of Coal Oil Point Reserve, Goleta, CA. Here is one of the raw images: And here’s a visualization of the small topographic and surface model variation derived from using ODM from the dataset.   edit: I’m really looking forward to trying … Continue reading OpenDroneMap — Orthophotos and Textured Mesh (Habitats)

OpenDroneMap — Orthophotos and Textured Mesh (testing…)

A few new features are about to land on OpenDroneMap. Among those features, we have great work led and implemented by Spotscale for orienting our textured meshes so that Z is up: and auto-exporting an orthophoto when GPS ephemeris is available in our input images: ——- Next step — testing the input of ground control points in order to output fully referenced and orthorectified imagery. … Continue reading OpenDroneMap — Orthophotos and Textured Mesh (testing…)

OpenDroneMap — Orthophotos and Textured Mesh (cont.)

(Credit goes to Brandon Garman for the graphic above. It’s part of a very nice sUAS graphic he’s putting together at the moment.) Following up on the earlier post on the addition of orthophotos and textured mesh to OpenDroneMap (FYI, one word, and not OpenDroneMaps) https://smathermather.wordpress.com/2014/12/22/opendronemap-orthophotos-and-textured-mesh/ we have some more features in the pipeline. This is a deeper dive into architecture and future enhancements. In the … Continue reading OpenDroneMap — Orthophotos and Textured Mesh (cont.)
