The Scottish Environmental Protection Agency has an ARCGis server with river data I'd like to query.
At this URL it shows what I want to get
I'm after finding the river classification at a given Longitude and Latitude.
The above URL uses British National Grid but I have only a Long and Lat. I think that means settings sr=3395
I'm wanting to get the river classification data in JSON for my PHP website. I've worked out this URL but it just says No Results Found.
What am I doing wrong in the above URL?
