Hi, I ‘m here again.
This time to speak about a very quick scripting .

A few days ago Oscar Martinez told me that he had seen a python library to access geocoding services , GeoPy ; but there was the problem that he was unable to use it in gvSIG … as it was designed for a newer python version than the one used in gvSIG.

While we were glancing , we realised that by changing few small things, it could become usable for the python version of gvSIG 2.1.0 .

To use GeoPy you have just to install the library , which can be done by unzipping the  “geopy-1.7.1-patched-for-gvSIG-2.1.0.zip” file in the folder:

gvSIG/plugins/org.gvsig.scripting.app.extension/lib/

located in user home. If you have already executed gvSIG, it should be closed and restart .

In Linux you can find this folder in $ HOME , and for Windows in :

C: \ Document and Settings \ my_user
or
C: \ Users \ my_user

Once installed the library GeoPy it can be used quite simply. If you execute the gvSIG scripts “Composer” , and create a new one with the following code , then you can start testing without any problems.

from gvsig import *
from commonsdialog import *

from geopy.geocoders import get_geocoder_for_service

def main(*args):

  street = inputbox("Insert street","street")
  if street == None:
    return
    
  geolocator = get_geocoder_for_service("googlev3")

  location = geolocator().geocode(street)

  print(location.address)
  print((location.latitude, location.longitude))
 
  msgbox("Found:\n"+location.address+"\n"+str((location.latitude, location.longitude)))

You can perform more complex actions such as open a table containing street names and civic addressing, read them and go creating a shapefile with points provided by geolocalisation service, but for the moment you can go on playing with this.

Greetings to all
