Class Number Final Land Cover Classes 1 Forest 2 Developed Definition 3 Fields/Pastures Vegetation land cover outside municipal areas 4 Wetland 5 Water 6 Barren 7 Open Space Vegetation land cover within municipal areas 8 Deforested-Dev Deforested for Development. Forested areas in 2000 that are currently classified as Developed. 9 Deforested-Other Deforested. Forested areas in 2000 that are currently classified as Fields/Pastures, Barren, or Open Space. 3.3.3.3 Land Cover Change Table 3-5. Land Cover Classes Change detection analysis compared 2010 SPOT-based classified images to EOSD land cover data from 2000. EOSD data were aggregated to forest and non-forest classes and compared to the classified land cover (Table 3-6). Given the coarser resolution of the EOSD compared with the SPOT image classification, a review of the 3 “sparse” forest classes in the table below was conducted to consider whether these pixels should be included in the Open Spaces or Fields/Pastures classes. Upon review, the sparse forest classes provided an accurate representation of sparse forest cover and were therefore kept in the forest class and subsequent analysis of deforested areas. Table 3-6 illustrates how the EOSD classes were aggregated for change detection. TA1112733 40

Original (left) and aggregated (right) classes used to identify forest loss between 2000 and the dates of image classification. It should be noted that the EOSD data lacks a land cover class representing impervious surfaces or related land use categories such as residential, commercial/industrial, or urban. Therefore, two types of deforestation were classified; areas that were forested in the 2000 EOSD which are now classified as developed (called “Deforested – Developed”) and areas that were forested in the 2000 EOSD which are currently classified as field/pasture, open space, or barren (called “Deforested – Other”). The EOSD water class was evaluated for the possibility of measuring change in water area. However, due to the highly variable nature of water depth, inconsistencies between image dates, and coarse resolution of the EOSD data, change detection for water area was not conducted. 3.3.3.4 Manual Corrections Primary edits required to improve consistency across land cover mosaics involved manual corrections to areas covered by shadows, clouds, and ice, and along image seamlines due to TA1112733 41
