Hi ymg
the problem is that with the method from
VovKa there is a restriction of 2,500 requests per day.
The Elevation API has the following limits in place:
Users of the free API:
2,500 requests per 24 hour period.
512 locations per request.
5 requests per second.
Is there no possibility to receive the elevation data from Google Earth? and to steer Google Erath?
