THE ESA RIVER AND LAKE SYSTEM: A USER ANALYSIS

摘要

The ESA River and Lake (R&L) system was introduced in 2005 to provide global river and lake height measurements using satellites radar altimetry. The system has been proved highly beneficial to an individual who is interested in water resources where insitu gauges are limited, particularly within the rural areas of Asia and Africa. Using the records from the very successful ESA River and Lake system, a detailed analysis of the system users has now been undertaken to investigate user geographic distribution and data requirements, and to assess trends among the user data. The main focus of this analysis was on geographical distribution of registered users, subscribed users and subscribed targets. Currently there are 1,507 registered users and 303 subscriptions to date 20/06/12. No of email subscriptions has been increased significantly, with 61 new subscriptions since last year.
