Table 1 Accuracy assessment of vegetation classification using field-based plot data. Areas where the mapped community matched the field-assessed community are highlighted in gray. Producer accuracy, or the percentage of field plots that were mapped correctly, is shown for each vegetation class in the bottom row. User accuracy, or the percentage of mapped polygons that corresponded with field plots of the same vegetation type, is shown in the far right column.
