[libreoffice-users] Calc: Using Internet Sites to Determine Driving Distances

Highly technical issue:

I have a spreadsheet that, among other things, contains street addresses. I need to 
determine the driving distance between pairs of addresses. From within Calc, how can I use 
a site on the internet (i.e. Open Street Maps, Google Maps, MapQuest, etc.) to determine the 
driving distance between two such street addresses? I suspect that I will need a user defined 
function such as DRDIST(from, to) to accomplish this but I don't know how to go about 
writing such a function. 

With A1 containing the address 2345 Weldon and another address being hard coded as 
4453 N Ashcroft I envision invoking this function as

  =DRDIST(A1&", Fresno, CA", "4453 N Ashcroft, Fresno, CA") 

and the result, in miles, would be something like 5.2. (Both of these addresses where I lived 
as a child no longer exist but I use them as examples of how the function would be invoked.)

It would be great if someone already has a function to accomplish this task and if it can be 
shared with me. If that is not the case, then I will probably need a lot of assistance to create 
such a function which can then be shared with the LO Calc community.
