The LRIS at BARC, the field data on the standing crop from the extension department and satellite imagery of the space research agency were used for location of the area of inundation and crops affected, and after random field checking, conclusions were drawn on the loss of the Aman rice crop. The use of LRIS confirmed that the flooding area in the 1998 is in good agreement with the national map of flood characteristics and flood hazard. Then the 1998 flood layer was combined with the Aman rice coverage layer (the major crop during the flood season); the function between the flood level and the crop damage was applied and aman rice crop loss layer was generated. The figures obtained were realistic and acceptable to the government.
