LAND USE MAPPING OF URBAN AREAS USING OBJECT-ORIENTED ANALYSIS OF QUICKBIRD IMAGES. This article introduces a new object-oriented image analysis methodology, whose aim is to distinguish between two types of land use: single-family and multi-family households. These categories, which are especially common in peri-urban areas, are so heterogeneous from the spectral point of view that a per-pixel approach does not allow for their unambiguous identification. Object-oriented analysis has proven suitable to distinguishing between these two categories, insofar as it is based on multi-resolution segmentation and on the scale, color, form, smoothness and compactness parameters. The concepts of single-family and multi-family households are discussed by means of reference to a new notion – that of composite object. |
