Bike use visualizations

posted Fri 23 May 2014 by Michael Galloy under Visualization

Strava is a popular app for tracking your runs and rides. But the accumulated data that can be explored through the Strava Labs Global Heatmap is amazing! It is fun to look around and explore my area’s use for rides and runs. (But, I could have told you that 4th St. was bike highway for people leaving town.)

Looks like Strava is now selling accumulated data to cities to help plan better bike routes. Portland is in.

About me

I'm a software developer focusing on high-performance computing and visualization in scientific programming. I work mostly in IDL, but occasionally use C, CUDA, and Python.

I currently work for the National Center for Atmospheric Research (NCAR) at the Mauna Loa Solar Observatory. Previously, I worked for Tech-X Corporation, where I was the main developer for GPULib, a library of IDL bindings for GPU accelerated computation routines.

I am the creator and main developer for the open source projects IDLdoc, mgunit, and rIDL.

Contact me at Mastodon or via email at mgalloy at gmail dot com. For more details about me, see my CV/resume.
