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…

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
