Extraction of rice planting area in Zhejiang Province using MODIS and NOAA/AVHRR

Abstract

Comparison of extracting areas of paddy fields of Zhejiang Province in 2002 using Moderate-Resolution Imaging Spectroradiometer (MODIS), Advance Very High Resolution Radiometer (AVHRR), geographic information system (GIS) and global position system (GPS) was reported in this paper. Training samples are selected and located with the help of GPS to provide maximal accuracy. A concept of assessing areas of potential cultivation of rice is suggested by means of GIS integration. MODIS data of September 1st, 2002 and NOAA/AVHRR data of September 2st, 2002 covering the whole of Zhejiang Province were acquired. By integration of Remote Sensing (RS), GIS and GPS technologies the actual areas of rice fields in 2002 have been mapped. The classification accuracy was 95.1% percent for MODIS and 92.7 percent for NOAA compared with the statistical data of the agricultural bureau of Zhejiang Province.
