Since many water fields, agriculture crops, and forest land cover types have the similar NDVI value with Rice crop (as shown in Table 4.1), it is necessary to use some limitation factor as terrain slope less than 5% (Suwanwerakamtorn and Hirunkul, 2012) with land use 2552 and Rice crops from Landsat 2558 classification. This data integration is used as boundary limitation for 16-day MOD13Q1 time series data classification for Rice Planting Stages as shown in Figure 4.8.
