I am trying to use the USGS Elevation Query Web Service Method to retrieve elevation (MSL) for a point specified by geographic coordinates ( latitude and longitude).
The documentation page at USGS doesn't make any sense to me. I can't figure out how to pass the parameters to the method in a url.
I see that I need to pass X_Value and Y_Value (lat & lng) to the method using
But, I can't find a way to specify the parameters.
This looks to me like it should be a simple thing to do if I only knew the syntax of the query.
I am awarding 200 points based on this assumption. If someone points out to me that this is a more complex problem than it looks like to me, I will increase the points accordingly.
