""" Rough notes on how to plot centred on a location using basemap
What I really want to do is implement a Karma Pi path something like
this:
locations/{location}/{item}
That will show you {item} from location's point of view.
Now {item} works best if it does not have any /'s, so for
the item parameter we'll convert /'s to ,'s and see how that looks.
The idea is {item} will be a path to something in Karma Pi.
So here is how it might go:
>>> parms = base.Parms()
>>> parms.path = "locations/bermuda"
>>> parms.item = "time,2015,11,01,precipitation,image"
>>> data = location(parms)
In the background, some magic will read lat/lon for
locations/bermuda, or rather read the meta data and hope the
info is there.
It will find the data for the precipitation image and use it to
create an image of the data using the "ortho" projection in basemap.
This shows a hemisphere of the world, centered on the location.
It would be good to offer other views.
This can be supported by adding different end points for each view
Eg:
>>> parms = base.Parms()
>>> parms.path = "locations/bermuda"
>>> parms.item = "time,2015,11,01,precipitation,mercator"
Might return a mercator projection.
>>> parms = base.Parms()
>>> parms.path = "locations/bermuda"
>>> parms.item = "time,2015,11,01,precipitation,tendegree"
Might return a 10 degree window around the location.
