Figure 3. An outline of the suggested absolute/relational classification and conceptual space representation. The human (H1–2) and machine knowledge elements (M1–7) are combined to produce a resulting proxy image for land use.

Figure 4. A map showing the location of the three different types of summer farms in the study area, and the result from the SRPC process overlaid on a b/w orthophoto, with the yellow color tone on developed areas and the green tone on other land. Type-1: In use; Type-2: Recently abandoned; Type-3: Overgrown.
