Geolife dataset

Dear mailing list members,

I am currently working with the Geolife dataset from Microsoft Asia (About
17.000 trajectories, mostly Beijing area). I want to analyze route usage
(for now only basic descriptives: how many trajectories use one same route,
hours of the day in which those routes are more popular). I want to ask you
if there is any specific package I should look at (so far I have seen
packages that only built a dataframe and make some basic plots).

Any ideas?

Best regards,

EV

I suggest you peruse through the Spatial task view (
http://cran.r-project.org/web/views/Spatial.html). Package `sp` lays down
the ground work (spatial classes like SpatialLines, SpatialPoints,
SpatialPolygons...), and there's a plethora of packages to tinker with this
or that.

Cheers,
Roman

Hi

It is difficult to tell from your email which packages you have been exploring so far. Perhaps the trajectories package? Did you have a look at the adehabitatLT package? See e.g. http://cran.r-project.org/web/packages/adehabitatLT/vignettes/adehabitatLT.pdf. 

Yours sincerely / Med venlig hilsen

when you are in the top directory of the geolife data set, start R, then

library(trajectories)
demo(geolife)

will read part of the data set. Copy the script [1] to this directory,
and start editing. Read the package vignettes to see what the package
can do for you.

Don't forget to report back to the list what the package can not do for
you, or consider contributing back to the package!

With best regards,

[1] found in the demo directory of the package, or alternatively on
https://github.com/edzer/trajectories/blob/master/demo/geolife.R
