1. Google static maps API. Really easy to use - basically just construct the URL to the google map image and you are off and running.
2. Get the visitor location (lat longitude) from their IP address. This was a bit trickier.
1. Visit https://developers.google.com/maps/documentation/staticmaps/ and read up on the creation of a google static map. In my case I stuck with the most basic implementation to keep things easy.
2. After searching for a while I found the best way to get from IP address to location was to use this web service: http://ipinfodb.com/ This service allows you to call an HTTP address and get back physical location information. The basic idea it to call the infodb URL like so:
URL = "http://api.ipinfodb.com/v3/ip-city/?key=" & locationKEY & "&ip=" & UserIPAddress
The result if you simply browse to this address is a semi-colon delimited string containing details like city/state and Lat;Long.
What I did was to create a classic asp function that returned the Lat,Long position like so:
Function getPosition(UserIPAddress) URL = "http://api.ipinfodb.com/v3/ip-city/?key=" & locationKEY & "&ip=" & UserIPAddress Set xmlHttp = Server.Createobject("MSXML2.ServerXMLHTTP") xmlHttp.Open "GET", URL, False xmlHttp.setRequestHeader "User-Agent", "asp httprequest" xmlHttp.setRequestHeader "content-type", "application/x-www-form-urlencoded" xmlHttp.Send getHTML = xmlHttp.responseText xmlHttp.abort() set xmlHttp = Nothing arrLocation = SPLIT(getHTML,";") strLatitude = arrLocation(8) strLongitude = arrLocation(9) strCoordinatesTemp = strLatitude & "," & strLongitude getPosition = strCoordinatesTemp END FUNCTION
Once this function was created, all I had to do was iterate through my latest visitors IP address to generate the actual map
'--get most recent 5 locations sqlGet = "select top(5) pr_ip_address,pr_index from tProfile order by pr_index desc" set objRsLocations = objConn.Execute(sqlGet) DO WHILE NOT objRsLocations.EOF strCoordinates = strCoordinates & "%7C" & getPosition(objRsLocations("pr_ip_address")) objRsLocations.MoveNext LOOP
Once that was done - just append the coordinates to the google static maps api url and you are good to go:
