Taken from google's documentation on it at: http://code.google.com/apis/maps/documentation/elevation/
Use of the Google Elevation API is subject to a query limit of 25,000 elevation location requests per day. Note that on any given query, you may request elevation data for multiple locations, which count as separate queries. Up to 512 locations may be queried within a single request. This limit is enforced to prevent abuse and/or repurposing of the Elevation API, and this limit may be changed in the future without notice. Additionally, we enforce a request rate limit to prevent abuse of the service. If you exceed the 24-hour limit or otherwise abuse the service, the Elevation API may stop working for you temporarily. If you continue to exceed this limit, your access to the Elevation API may be blocked. The Elevation API returns data for single point queries of the highest accuracy possible. Batch queries involving multiple locations may return data with less accuracy, especially if the locations are spread apart, as some smoothing of data occurs. Note: the Elevation API may only be used in conjunction with displaying results on a Google map; using elevation data without displaying a map for which elevation data was requested is prohibited. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions<http://code.google.com/apis/maps/terms.html#section_10_12> . Then the post Rossko posted gives you more detailed explanations about the usage limiations.
