After several release candidates and getting the hang of a new review and release process as part of GeoTrellis’ journey to be a LocationTech-incubated project, we’re proud to announce that GeoTrellis 0.9 – codenamed “Avalon” – is officially released!

We announce that we’ve submitted GeoTrellis, a high-performance geospatial data processing framework, to LocationTech, a new working group at the Eclipse Foundation focused on geospatial open-source projects.
In this blog we describe GTFS, the General Transit Feed Specification and outline some of our work with it.

In a previous post I compared Sprite Kit physics to using Box2D directly. In that comparison I used frames per second as measured by Instruments, but it is useful to look at straight simulation time (ignoring rendering time), which I present here.
I have recently done some work with Sprite Kit and have made some observations regarding the built in physics simulation capabilities. Based on these observations, I have decied to take a closer look at Sprite Kit physics, specifically comparing it to using Box2D directly.
In this blog we describe how to run parameterized tests in iOS.
This guide demonstrates how to get your Test environment in Android Studio up and running using the Gradle build system.
In this post we describe our experience applying the DRY principle while using a Vagrant file to launch a Riak cluster on Amazon Web Services (AWS) Elastic Compute Cloud (EC2).
In this blog, we discuss our experience calculating travelsheds and transit accessibility using GeoTrellis Transit.
