More Map Scripts

In the last installment‎ I wrote a script (gdal_slice.py) to cut up geotagged images and save them in a format that GPSdrive will read. I’ve uploaded that script into a new repository on GitHub. I’ve also uploaded a script I wrote called get_quad.py, which will download USGS topographic maps automatically. This script naturally complements gdal_slice.py; […]

Bluetooth Android GPS on OS X

Inspired by this link from the GPSd homepage I set out to use my brand new Android phone as a bluetooth gps. Naturally, I wanted to use it with GPSd, but on OS X. I read through the Linux directions and thought “this shouldn’t be terribly hard on a Mac!” As it turns out, I was right! […]

One thing that caught my attention on this reading (especially in light of my recent GPS post) is the way that one of the main […]

GPSd under OS X (revisited)

It’s been almost 2 and half years since I originally posted about GPSd and OS X. That post got quite a bit of traffic for a while, but a whole lot has changed since then. If you’re interested in some in-depth background information, you should check out the old post; this post is mostly about […]

GPSd under OS X

Update 7-13-11: I’ve posted an updated set of instructions on getting GPSd to compile on OS X here; this post will remain for archival purposes. For information on installing GPSDrive, see this post. So I recently picked up a cheap GPS module on Amazon. It was about $30 with shipping, and I got a neat […]
