Hägerstrand Time-Space Cube

Hägerstrand time-space cube with R
With the rgl package it’s possible to interact with the 3d visualization of the timespace tracks.
Code example:
plot3d(lon,lat,timedate, xlim=range(lon), ylim=range(lat), zlim=range(timedate), ticktype=”detailed”, xlab=”longitude”, ylab=”latitude”, zlab=”Date”, col= as.POSIXlt(daten[,"Date"])$mday, type=”l”, main=plottitle)
In the posted example individual waypoints were added by drawing vertical lines.

Hi,
this looks really nice! It would be great though, if your code was reproducible, so anyone interested can play around with it on their own computer…
Cheers,
Mark

Thank you for your interest. This type of visualization is not a big deal. Just install the rgl package and import some gps trackdata a cvs file. The tracks timestamps should be merged (Time+Date) to a timedate format which is possible with the timedate package. You can also take any other data with 3 dimensions like underground earthquake coordinates. For further questions you can contact me any time.

[...] had mentioned the ideas of geographer Torsten Hägerstrand mapping location against time (see http://geolabs.wordpress.com/2010/11/30/hagerstrand-timespacecube/ for an example). In the digital age Hägerstrand’s map would need a new axis – location in [...]
