英文摘要: An image dataset from the Landsat OLI spaceborne sensor is compared with the Landsat TM in order toevaluate the excellence of the new imagery in urban landcover classification. Widely known pixel-basedand object-based image analysis methods have been implemented in this work like Maximum Likeli-hood, Support Vector Machine, k-Nearest Neighbor, Feature Analyst and Sub-pixel. Classification resultsfrom Landsat OLI provide more accurate results comparing to the Landsat TM. Object-based classifica-tions produced a more uniform result, but suffer from the absorption of small rare classes into largehomogenous areas, as a consequence of the segmentation, merging and the spatial parameters in thespatial resolution (30 m) of Landsat images. Based exclusively on the overall accuracy reports, the SVMpixel-based classification from Landsat 8 proved to be the most accurate for the purpose of mappingurban land cover, using medium spatial resolution imagery. © 2014 Elsevier B.V.
