Is it possible to Calculate distance (and possibly direction)  between a user specified address\postcode and an address\postcode in my database using coldfusion and one of the map-services like Mapquest or Yahoo Map?  I would like to send information to one of these sites and get the results back without using my own zipfind DB.

For example,
http://www.ups.com/using/services/locate/locate.html 

but doesn't have to be as detailed as this.

I would greatly appreciate your help on this.

Thank you,

-RVV

You can search for address also, but if it doesn't find an exact match, you won't get a distance...


<CFSET addr1       = "">
<CFSET city1       = "">
<CFSET state1      = "CA">
<CFSET zip1       = "90210">
<CFSET country1 = "US">

<CFSET addr2      = "">
<CFSET city2      = "">
<CFSET state2      = "NY">
<CFSET zip2       = "10101">
<CFSET country2 = "US">

<CFSET searchstring = "go=1&do=nw&ct=NA">
<CFSET searchstring = searchstring & "&1y=#country1#&1a=#addr1#&1c=#city1#&1s=#state1#&1z=#zip1#&1ah=">
<CFSET searchstring = searchstring & "&2y=#country2#&2a=#addr2#&2c=#city2#&2s=#state2#&2z=#zip2#&2ah=">

<CFHTTP url="http://www.mapquest.com/directions/main.adp?#searchstring#"></cfhttp>

<CFSET result = cfhttp.filecontent>
<CFSET start = FINDNOCASE("Total Distance:",result)>
<CFSET end = FINDNOCASE("miles",result,start+1)>

<CFIF val(start) AND val(end) AND end gt start>
      <CFSET distance = REREPLACENOCASE(MID(result,start,end-start),"[^0-9]*([0-9,.]*).*","\1","ALL")>
