A thematic map is a vector or raster map of themes such as land-cover types, soil types, land use, or forest types. Thematic map classes are discrete, not continuous. A thematic map covers the entire area of the landscape and labels everything into thematic classes. Figure 2.6 is an example of a thematic map of land-cover types for an area of the Coastal Watershed in southeastern New Hampshire. Thematic maps are created through manual interpretation of imagery or semiautomated image classification.
