Hi all, I am developing an application which displays map using Google Map API. I am also drawing a path using polyline function. Now I have to get altitudes of cartian locations on the path. Google map API directly doesnt provide anything for this. One must use web services like http://ws.geonames.org/srtm3?lat=50.01&lng=10.2&style=full I dont know anything about usage of this kind of web services. Can somebody tell me how can I embed this web service in my jsp to get the result. Actually I will use the result returned for plotting a graph. So I am thinking of sending latitude and longitude in batch to get the altitudes in batch. Can anybody tell me is there any web service for this? And also hoe to use it in jsp.
