Abstract: The repeated gravity observation data in Sichuan area from 1987 to 2012 had been preliminarily compilated by using standard surveying point numbers, correcting the mistakes of the latitude, longitude and the abnormal points in the historical data and counting point numbers. The work had made the repeated gravity data in Sichuan area in the period 1987—2012 more completed, clearer and form the sharing basis of gravity data of the Sichuanarea. The standard and systemic data can provide the scientific support for studying gravity changes associated with earthquake activity in Sichuan area.

Key words: Repeated gravity observation data, Data sharing, Sichuan area
