Sao Jose dos Campos, SP, Brazil, 1977. Figure 2.1 shows an example of the result of the delineating process for residential sectors through the differentiation of the photographic textures. This aerial photograph clearly shows the differences between the textures 1, 2, 3 and 4 which are marked and allow the definition of four urban residential sectors. Texture 1 is coarser than the other ones, i.e. its primary elements are larger. It is defined by a few large houses and large lots, many of which still unoccupied, spatially organized along the streets that constitute the road system of the sector that is regular, with parallel lines ending up in "dead ends". Texture 2 introduces a more heterogeneous composition as far as its component elements are concerned. It is an urban reneval area in which can be seen large-size apartment houses, side-by-side with one-storey houses. Such elements are matched according to a spatial organization pattern that gives the area an overall homogeneous appearance. Texture 3 is slimmer, i.e. made up from primary elements smaller than in the preceding texture. It is defined by one-family houses, smaller than the ones in the areas of the previous textures. The occupation is dense, not only because of the relationship, per area, between constructed and empty areas, inside the lot, but also because there are hardly any unoccupied lots left. Texture 4 is defined by the presence of slightly larger houses than the ones described in the texture 3 area. Furthermore, there are many unoccupied areas, as well as a great deal of arborization, which gives the area an aspect that is well-differentiated from that of the previous areas. The delineating of homogeneously-texture residential areas is a task that depends on the photointerpreter's capacity for discriminating between determined simpler textures and, by means of more developed cognitive processes, discriminating between more complex textures. The execution of this task requires not only the study of photointerpretation techniques, but also specific knowledge of architecture and urbanism.
