*: the elevation services srtm3 and astergdem allow to pass a list of lats/lngs. In this case the credits used depend on how much the cache can be used. Several idential or nearly idential lat/lng in the list will count as only one. The formula used is: Math .max( credits, credits * (elevationResult.elevationCredits.numDistinctTiles + elevationResult.elevationCredits.numDistinctPositions) / 2.0);

All other web services need 1 credit per request.
