Change in land use/cover from 2013/14 to 2017/18 was interpreted by translating changes in land cover to changes in land use consistent with the 54 unique land use/cover classes in the 2017/18 land use dataset. Changes in land cover were primarily based on multi-date LiDAR imagery if available followed by multi-date NAIP imagery (available for all counties). Similar rules and logic used to classify the 2013/14 land cover data were applied to the change objects to produce a comparable land cover dataset for 2017/18. While some changes in land cover translate directly into changes in land use (e.g., impervious structures), others had to be interpreted based on context (e.g., small fragmented patches of tree canopy reconstituted as forest in 2013/14; turf grass in a newly developed parcel interpreted as cropland prior to development in 2013/14). Transitions between turf grass, cropland, pasture, and natural succession are not evident in the land cover data but are evident in the land use data. For this reason, the extent of land use change is greater than the extent of land cover change.
