摘要 | Multiple classifications of a Landsat Thematic Mapper (TM) image resulted in 23 thematic maps for an area of 31,660 ha in central Indiana in the United States. Each map consists of four land use and land cover types (classes): urban, agricultural land, forest, and water A common set of reference data was randomly sampled from the image and was used to evaluate the classification accuracy of each of the 23 maps. The classification accuracy of these maps was between 77.6 to 89.2%. Landscape index values for nine landscape-level indices and nine class-level indices were derived from the 23 maps. Although the majority of the thematic maps were not significantly, different in overall accuracy, the landscape index values showed high variation among the maps. The results suggested that the variation of landscape index values is inversely, proportional to classification accuracy. Therefore, when classification accuracy is lower, the uncertainties of landscape characterization become higher Unfortunately, such uncertainties are not readily, predictable because landscape index values can be altered by the magnitude and spatial distribution of classification errors. Classification accuracy alone is not sufficient to ensure the accuracy of landscape characterization. |
