Fig. 6. Image classification result for the study area. The polygon layers of the 2017 GPR data are successfully classified into class 1 (i.e., buried heritage) and class 2 (i.e., background). Only class 1 polygons classified in the 2017 data are filled with green. The same classification model developed from the 2017 GPR data as shown in Figure 5b is applied to classify the 2016 data. Although the 2016 data are not incorporated into the classification model, the polygons associated with the buried heritages are consistently classified as class 1 (purple-filled polygons).
