| - Number of automatic accesses to the HelioClim data (per year, in million of requests) |
 |
This graph depicts the yearly number of requests of automatic accesses (machine-to-machine accesses, wget or curl command) to the HelioClim databases (HC1, HC3) since the introduction of the SoDa website in 2002. In the first months of 2011, the duplication of the acquisition chain at Transvalor premises, in Mougins, France, enables a better service, and wget access to our Customers.
In 2011, more than 1 750 000 millions of automatic requests were made to the HelioClim databases.
