Dev: SM: Elevations API
The Streetmaps Elevations API V2 is based on the Google Elevations API. It is a drop-in replacement with some enhancements.
For the base documentation, consult The Google Elevation API. The base URL has changed from http://maps.googleapis.com/maps/api/elevation to https://www.streetmaps.co.za/api/elevation/xml - all the arguments work the same.
You need to specify your API key in the parameters with key=<YOURKEY>.
Currently, the service is fairly slow as it's in a beta form. Performance increases and optimization are planned.
