Help Creating a Jump to Google Tool with Python

jennifersylvester

I am working to create a tool in python that will take the current extent of the map in ArcMap 10 and create a hyperlink to jump to googlemaps at the same location.

In VBA the link was created from this:
  pHyperlink.Link = "http://maps.google.com/maps?ll=" & pPoint.y & "," & pPoint.x
with the point derived from this:
  x = ((pEnvelope.XMax - pEnvelope.XMin) / 2) + pEnvelope.XMin
  y = ((pEnvelope.YMax - pEnvelope.YMin) / 2) + pEnvelope.YMin

How do I replicate this with python?


So far I have:
import webbrowser
url = 'http://www.googlemaps.com/'
webbrowser.open_new_tab(url)

Thanks,
Jenn

got it. it is unprojected NAD83


Script:

import webbrowser, arcpy

mxd = arcpy.mapping.MapDocument("current")
dataFrame = arcpy.mapping.ListDataFrames(mxd)[0]

externalScales = [192000000,96000000,48000000,24000000,12000000,6000000,3000000,1500000,725000,350000,188000,93000,46000,23000,9000,4500,2250]
currentScale = dataFrame.scale
current = 0
previous = 200000000
z = 0
counter = 0

for scale in externalScales:
    #print scale
    current = math.fabs(currentScale - scale)
    if current < previous:
        previous = current
        z = counter
    counter += 1

x = (dataFrame.extent.XMin + dataFrame.extent.XMax)/2
y = (dataFrame.extent.YMin + dataFrame.extent.YMax)/2

thelink = "http://maps.google.com/maps?ll="
thelink = thelink + str(y) + "," + str(x) + "&z=" + str(z)
webbrowser.open_new_tab(thelink)
