15. Using geo-informatics technology in the 2nd phase paddy field acreage verification The government initiated the price scheme for paddy field farmers in 2009/2010, this would enable the farmers in less pricing risk with certain income. The cabinet resolution on 25 August 2009 proclaimed the committees on the price scheme for the farmer, In 23 February 2010, the resolution accolade GISTDA/MOST in using GIS in the acreage verification, coupling with the national paddy field database in 2009/2010. So THEOS data were used to determined the number of acreage for reimbursement. Furthermore, the satellite image interpretation process had to be reported on a continually basis, up to the end of July 2010. At present, the 1: 25,000 satellite image of the nationwide paddy field had been archived and reported, with the number of acreage, in the northern and the central regions.
