Mapping Hacks

Schuyler wrote a python module to support the Geohash latitude/longitude encoding system created by Gustavo Niemeyer. (wikipedia link).
Schuyler’s python implementation of geohashing code is here.
Geohashing is not to be confused with the more amusing but arguably less useful xkcd geohashing, an implementation of that code lives here .
There is of course also an […]

A member of the Geowanking list asked for advice on pulling 700×700 element chunks out of a 50,000×50,000 element raster file.
And doing it in under 10 seconds, please.  That brings up the magical GDAL tools.  The Geodata Abstraction Library.  This is a set of libraries and command line tools which let you do just about […]

Bill Woodcock forwarded me this blog post with an awesome map of the United States as seen from Japan.  The Thing That Is Scary is how the fanciful map does reflect certain aspects of reality.
Certain aspects

In spite of the enormous press, and the pretty pictures, Google Earth represents the pre-infancy of user oriented spatial tools.
I hate to be ‘just’ a freaking whiner…so I have been actively trying to use the darn thing as part of my attempts to collect and manage the raw data from my experiences.
Sadly every time […]

Sunday morning a gasoline tanker tipped over and caught on fire.   Unfortunately this caused a connector road which is mega-important to bay area traffic to collapse.
I got a call Sunday from Matt Petty at sfgate.com with a Google Earth question.  With a tiny bit of help from me they created a cool animation showing where […]

In Mapping Hacks, the book, Schuyler wrote a program to convert a track log in a text file into a Shapefile.  We mentioned, perhaps optimistically, that a version to convert a gpx (a GPS XML exchange format) track lot to a shapefile would be on the web site.
Optimism while writing is a good, and a […]

Harry Beck’s schematic map of London’s Tube network is constantly cited as a design classic and a cartographic inspiration. I am one of many people who’ve made a “spatially accurate” version of the Tube map for kicks.
ChrisDodo pointed us at an interesting spin on the idea - a schematic map of the UK motorway network. […]

I’ve been running around saying ‘when is the next where’ for a bit now.     I sort of assumed it was an established meme that I was jumping on the back of, looking for uh, seconds…but a glance at Google finds zero hits for “when is the next where,” and a grep of the […]

Our friend Mike Liebhold is on this http://buildwebsites.net/blogs/michigan-web-design/8590/
It is an interesting podcast in which fun things are said…read the link, listen, have fun.

We wrote about http://www.weatherbonk.com in _Google Maps Hacks_. At the time it was sort of primitive-weather on a map. Now it is much cooler with version 2.
