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.)

Airspace — A deep rabbit hole

In previous maps we looked at Class B, C, and D airspace. Let’s add in Class E0 and E5… (not yet in 3D): (Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under ODbL) Previous posts: https://smathermather.wordpress.com/2014/10/25/airspace-is-complicated-and-so-i-abuse-postgis-once-again/ and https://smathermather.wordpress.com/2014/10/25/airspace-is-complicated-and-so-i-abuse-postgis-once-again-reprise/ Continue reading Airspace — A deep rabbit hole

Airspace is complicated — and so I abuse PostGIS once again — Reprise…

In the previous post: https://smathermather.wordpress.com/2014/10/25/airspace-is-complicated-and-so-i-abuse-postgis-once-again/ we explore the 3D shape and complexity of controlled airspace. Now here’s the rest of the code. We’ll add our affine transformation ala Seth Fitsimmons: And integrate that into our original function: And voila! Let’s take a look at Washington, DC and surrounds, another nice complicated example: And again with map tiles by Stamen Design, under CC BY 3.0. Data … Continue reading Airspace is complicated — and so I abuse PostGIS once again — Reprise…

Airspace is complicated — and so I abuse PostGIS once again

Let’s ignore for a moment the drone hobbiest / enthusiast. What is the shape of airspace for airplanes and commercial and government unmanned aircraft flying under Certificates of Authorization, and how can we visualize it? Thanks to Anita in the last post, we have the Class B,C,D,E Airspace Shape Files which helps us define the overall shape of controlled airspace. But, these are 3D things. … Continue reading Airspace is complicated — and so I abuse PostGIS once again
